While Salacia is designed to be safe for your lawn, there is a potential for yellowing if the product is applied too heavily or mixed too strongly. We strongly suggest adhering closely to the label's guidelines and recommend conducting a test spray on a small area before treating the entire lawn.

Selective herbicides exploit fundamental biological differences between broadleaf weeds (dicots) and grasses (monocots). These plant groups have different leaf structures, growth points, and tissue composition. Synthetic selective herbicides typically mimic plant hormones that only broadleaf plants respond to. Salacia uses osmotic dehydration — its naturally derived formula draws moisture from broad, exposed weed tissue while narrow grass blades retain enough moisture to recover. The selectivity comes from how different plant architectures respond to the same mechanism.

Osmotic dehydration is a physical process where a concentrated solution draws water out of plant cells through osmosis. When Salacia is applied to weed foliage, the naturally derived formula creates a high-concentration environment on the leaf surface that pulls moisture out of the plant tissue. The weed cells lose turgor pressure, the tissue collapses, and the plant dehydrates from the leaves down through the crown. This is a physical mechanism — not a chemical poison — which is why there is no synthetic residue left in the soil after application.

The answer depends on the product and the application technique. Synthetic selective herbicides using auxin mimics are systemic — they move through the plant vascular system to reach the roots. Salacia works through contact-based dehydration, killing the crown and basal growth tissue where the above-ground plant meets the root system. For deep-rooted weeds like dandelions, applying directly into the crown rosette ensures the product reaches the critical growth point. Most broadleaf weeds treated this way do not regrow.

Weeds with extensive underground root systems — like thistle, bindweed, and ground ivy — can store enough energy in deep roots to send up new shoots even after the above-ground plant is killed. The root network can extend several feet underground and regenerate from fragments. Multiple applications spaced one to two weeks apart exhaust these energy reserves. Each application kills the new growth, and eventually the root system runs out of stored energy to produce more shoots. Most common lawn weeds require only one application.

On broadleaf lawn weeds — dandelions, clover, wild violet, ground ivy, chickweed, henbit — Salacia delivers comparable control to synthetic selective herbicides. The mechanism is different (dehydration vs. hormone disruption), but the outcome is the same: the weed dies and the grass stays. University extension research confirms that contact-based organic herbicides are most effective when applied during active growth in temperatures between 60 and 80 degrees Fahrenheit, with thorough coverage of all weed surfaces.

For Salacia, the recommendation is to let the lawn dry before pets return — but the reason is efficacy, not safety. Salacia is labeled Pet Friendly because its naturally derived formula targets plant biology through dehydration, not animal biology. Dogs are attracted to the saline-based formula, and if they lick treated foliage before it is fully absorbed, they disrupt the application on the weed. Letting the lawn dry ensures the product has time to work on the weed tissue.

A selective weed killer targets specific plant types — typically broadleaf weeds — while leaving surrounding grass and desirable vegetation completely unharmed. A non-selective weed killer destroys all vegetation it contacts, including grass, flowers, and shrubs. If you need to remove weeds from a lawn without killing the turf, a selective herbicide is the only option that delivers targeted control. Salacia, the first OMRI-certified selective herbicide, gives homeowners an organic option that was previously unavailable in this category.

Yes. Until recently, every organic herbicide on the market was non-selective — meaning it killed everything it touched, grass included. Salacia changed that. It is the first OMRI-certified herbicide with true selective action, using Hybrisal Technology to control broadleaf weeds at one mixing rate while leaving grass unharmed. At a higher mixing rate, it switches to non-selective mode for driveways and hardscapes. No other organic product offers this dual capability.

Broadleaf selective herbicides control weeds like dandelions, clover, ground ivy (creeping charlie), wild violet, chickweed, henbit, bindweed, oxalis, and purple deadnettle. Grassy selective herbicides target weed grasses that invade lawns. Salacia controls over 100 broadleaf weed species at its selective mixing rate — including many of the most common lawn weeds homeowners struggle with — while keeping turf intact.

Most broadleaf selective herbicides are compatible with both cool-season grasses (Kentucky bluegrass, fescue, perennial ryegrass) and warm-season grasses (Bermuda, zoysia, St. Augustine). Salacia has been tested across these turf types with no damage at the selective mixing rate. The key is applying correctly — targeting the weeds directly rather than blanket-spraying the entire lawn — and following the label mixing rate for selective use.

It depends on the product. Many synthetic selective herbicides contain 2,4-D or dicamba, which university veterinary research has linked to health concerns in dogs. Salacia is labeled Pet Friendly because its naturally derived formula works through dehydration — a physical mechanism that targets plant biology, not animal biology. The reason to let the lawn dry before pets return is efficacy, not safety: dogs are attracted to the saline-based formula and may lick treated foliage before it is absorbed, disrupting the application.

The best window is during active weed growth — typically early spring (March through May) and early fall (September through October) when weeds are photosynthesizing and absorbing product most effectively. Apply on calm mornings with temperatures between 60 and 80 degrees Fahrenheit, with no rain expected for at least 24 hours. Avoid midsummer heat above 85 degrees, as stressed weeds absorb less product. For a complete seasonal calendar, see the Lanaturo timing and application guide.

A selective herbicide targets specific weed types — typically broadleaf weeds — while leaving surrounding grass and desirable plants unharmed. A non-selective herbicide kills all vegetation it contacts, including grass, flowers, and shrubs. If you need to remove weeds from a lawn, you need a selective herbicide. If you need to clear a driveway or fence line, you need a non-selective herbicide. Most homeowners need both types for complete property coverage.

Until recently, no. Every herbicide was locked into one mode — either selective or non-selective. Salacia by Lanaturo changed this with Hybrisal Technology. At the selective mixing rate, it targets broadleaf weeds while leaving grass unharmed. At a higher mixing rate, it switches to non-selective mode for driveways, sidewalks, and hardscapes. One product, two modes, controlled entirely by how you mix it.

Yes. Salacia is the first OMRI-certified selective herbicide on the market. Before Salacia, every organic herbicide was non-selective — it killed everything it contacted, grass included. Salacia uses osmotic dehydration to target broadleaf weeds while leaving grass unharmed, and it carries both OMRI certification and a Pet Friendly label designation.

Use a selective herbicide when you want to kill weeds in a lawn or turf area without damaging the grass. Use a non-selective herbicide when you want to clear all vegetation from driveways, sidewalks, fence lines, gravel areas, or garden beds before replanting. If you have both situations on your property — which most homeowners do — you traditionally needed two separate products.

Common selective herbicides include synthetic products containing 2,4-D, dicamba, or triclopyr, and Salacia (organic, OMRI-certified). Common non-selective herbicides include glyphosate-based products, vinegar-based organic sprays, and citric acid solutions. Salacia is unique in that it functions as both selective and non-selective depending on the mixing rate.

Yes. A non-selective herbicide kills all vegetation it contacts — weeds, grass, flowers, and any other plant. Never apply a non-selective herbicide to a lawn you want to keep. This is the most common mistake homeowners make: using a non-selective product (like vinegar spray or glyphosate) on lawn weeds and killing the surrounding turf along with the weeds. For lawns, always use a selective herbicide.

Salacia carries a Pet Friendly label designation and is OMRI certified organic, made from naturally derived ingredients. It works by dehydrating weeds — a physical mechanism, not a chemical one. No glyphosate, no 2,4-D, no synthetic chemicals. See what peer-reviewed research says about pet friendly weed killers.

Yes — organic weed killers made from naturally derived ingredients are significantly safer for pets than synthetic herbicides. Products with OMRI certification and EPA minimum-risk status, like Salacia, have been independently verified. That said, keep pets off treated areas until the product dries (1–2 hours), and store concentrates out of reach.

With organic herbicides like Salacia, pets can return to treated areas once the product has dried — typically 1 to 2 hours depending on temperature and humidity. Compare this to synthetic herbicides, where researchers have detected chemical residues on grass for at least 48 hours after application.

Yes. A peer-reviewed six-year study at Tufts University found that dogs exposed to professionally applied lawn pesticides had a 70% higher risk of canine malignant lymphoma. A Purdue University study found up to 7× higher bladder cancer rates in certain breeds. These studies focused on common chemicals like 2,4-D, dicamba, and glyphosate.

Look for three things: (1) OMRI certification — meaning independently verified organic ingredients, (2) EPA minimum-risk pesticide status, and (3) a formulation free of glyphosate, 2,4-D, dicamba, and triclopyr. Also check whether the product is selective (kills weeds only) or non-selective (kills everything including grass).

When used according to the label instructions, Salacia typically shows effects of control within hours. The product is designed to act quickly, so you can usually expect to see noticeable results in a short amount of time.

Visible effects on weeds can be seen within hours of application under optimal conditions, with complete weed control typically occurring within one to two weeks.

Most weeds require just one application of Salacia for effective control. However, some stubborn weeds may need up to three applications to achieve optimal results. It's important to remember that even after successfully controlling existing weeds, new ones may emerge due to weed seeds remaining in the soil. To enhance weed control in lawns, a combination of fertilizing and overseeding is recommended.

Early morning is the best time to apply weed killer — typically between 7 AM and 10 AM. Temperatures are moderate, wind is usually calm, and dew has dried from the lawn. Avoid midday and afternoon applications when heat causes rapid evaporation that reduces product absorption. Evening applications can work but risk dew forming overnight before the product is fully absorbed. The key factor is that the product needs to remain on the weed foliage long enough to be absorbed — calm, moderate conditions maximize that contact time.

The optimal temperature range for applying weed killer is 60 to 80 degrees Fahrenheit. Within this range, weeds are actively photosynthesizing and absorbing product through their leaves most effectively. Below 50 degrees, weed metabolic activity slows and absorption drops significantly. Above 85 degrees, grass stress increases and some herbicides can cause turf damage. Salacia performs best in the 60 to 80 degree range because its dehydration mechanism works most effectively on actively transpiring plant tissue.

Mow before applying weed killer — ideally one to two days before treatment. Mowing exposes weed crowns and growth points that are normally hidden under grass height, giving the spray direct access to the tissue that needs to be treated. Do not mow for at least two to three days after application, as mowing removes treated foliage before the product has been fully absorbed. For rosette weeds like dandelions, the crown is the primary target — mowing first ensures the spray pools into the center of the rosette where the growth tissue sits.

No. Rain washes the product off weed foliage before it can be absorbed, significantly reducing effectiveness. Check the forecast and ensure no rain is expected for at least 24 hours after application. If unexpected rain occurs within a few hours of spraying, you will likely need to reapply once conditions dry out. This applies to all contact-based herbicides including Salacia — the product needs to remain on the weed tissue long enough for osmotic dehydration to begin drawing moisture from the plant cells.

Spring (March through May) and early fall (September through October) are the two best windows for weed killer application. In spring, annual and perennial weeds are emerging and actively growing — the most vulnerable stage for treatment. In fall, perennial weeds like dandelions and clover are storing energy for winter, making them highly absorptive of herbicide applications. Summer treatments can work but require careful timing around morning hours to avoid heat stress on both weeds and turf. Winter is ineffective because weeds are dormant and not absorbing product.

The USGS National Water-Quality Assessment Program has found synthetic pesticide residues in over 90 percent of tested US streams and rivers, and in roughly 50 percent of shallow wells in agricultural regions. Whether these compounds reach your specific tap depends on your water source, local agricultural activity, and your water treatment facility. Urban and suburban areas are not immune — residential lawn chemical runoff is a significant contributor to watershed contamination, particularly after rain events.

Atrazine, glyphosate, 2,4-D, and metolachlor are among the most frequently detected herbicide residues in US water supplies according to USGS monitoring data. Atrazine is particularly persistent, with a soil half-life of 60 to 100 days and documented presence in groundwater years after the last application. Glyphosate — classified as "probably carcinogenic" by the IARC — is the most heavily used herbicide globally and is routinely detected in both surface water and groundwater samples.

Synthetic herbicides applied to lawns enter waterways through three primary pathways: surface runoff during rain events carries the compounds into storm drains and streams; soil leaching moves residues downward through the soil profile into groundwater; and volatilization allows some compounds like dicamba to evaporate and be carried by wind before settling on water surfaces. Residential lawns are a significant source — some studies show that suburban areas apply more pesticide per acre than most agricultural operations.

Organic herbicides made from naturally derived ingredients work through physical mechanisms like dehydration rather than persistent synthetic chemistry. They break down naturally in the environment and do not leave the kind of persistent residues that USGS monitoring detects in streams and groundwater. Salacia, the first OMRI-certified selective herbicide, uses osmotic dehydration to kill weeds — there is no synthetic compound that accumulates in soil or washes into waterways. This is why OMRI certification matters: it verifies that a product meets organic standards designed to protect environmental systems.

The USGS National Water-Quality Assessment Program is the most comprehensive long-term study of pesticide contamination in US water systems. Key findings include: synthetic pesticide residues detected in over 90 percent of tested agricultural streams, roughly 50 percent of shallow wells in farming regions showing contamination, urban waterways containing glyphosate, atrazine, and 2,4-D from residential applications, and pesticide concentration spikes after spring and summer rain events. The data spans decades of monitoring across hundreds of sampling sites nationwide.

Research from multiple institutions documents health concerns associated with synthetic herbicide exposure. The International Agency for Research on Cancer (IARC), a branch of the World Health Organization, classified glyphosate as "probably carcinogenic to humans" in 2015 based on epidemiological studies, animal studies, and mechanistic evidence. Studies on 2,4-D have found associations with non-Hodgkin lymphoma in agricultural workers. Dicamba has been linked to elevated risks of liver cancer and chronic lymphocytic leukemia. These findings come from peer-reviewed research published in major scientific journals — not speculation.

Pets face heightened exposure because they walk on treated surfaces, lie on treated grass, and groom their paws and fur. Research from Tufts University and Purdue University has examined associations between lawn chemical exposure and cancer rates in dogs — particularly bladder cancer in Scottish Terriers and lymphoma in multiple breeds. Synthetic herbicides settle on grass at the level where pets are most active. An OMRI-certified organic herbicide like Salacia works through dehydration — a physical mechanism that targets plant biology, not animal biology — and carries a Pet Friendly designation on its label.

Yes. The USGS National Water-Quality Assessment Program has documented synthetic herbicide residues in over 90 percent of tested US streams and rivers. These compounds leach through soil into groundwater and run off into surface waterways, particularly after rain events following lawn and agricultural applications. Atrazine, 2,4-D, and glyphosate are among the most frequently detected herbicides in US water supplies. Organic herbicides made from naturally derived ingredients do not contribute to this contamination cycle because they break down naturally and leave no persistent synthetic residue.

In 2015, the International Agency for Research on Cancer — a specialized agency of the World Health Organization — classified glyphosate as a Group 2A carcinogen, meaning "probably carcinogenic to humans." This classification was based on limited evidence of cancer in humans (specifically non-Hodgkin lymphoma), sufficient evidence of cancer in experimental animals, and strong evidence of genotoxicity and oxidative stress. Group 2A is the second-highest cancer risk classification IARC issues, below only Group 1 (confirmed carcinogen).

OMRI-certified organic herbicides offer weed control without the documented risks of synthetic compounds. Salacia is the first OMRI-certified selective herbicide — meaning it kills broadleaf weeds like dandelions, clover, and ground ivy while leaving grass unharmed, using naturally derived ingredients that work through osmotic dehydration rather than synthetic chemical disruption. The product is labeled Pet Friendly, leaves no synthetic residue in soil, and does not contribute to waterway contamination. It delivers the targeted weed control homeowners need without the hidden costs that come with synthetic chemistry.

Persistence varies by compound. Glyphosate has a soil half-life ranging from a few days to several months depending on soil conditions, microbial activity, and pH. 2,4-D typically degrades in one to four weeks but can persist longer in cold or dry conditions. Dicamba has a half-life of one to four weeks in soil. Atrazine is among the most persistent, with a half-life of 60 to 100 days in soil and documented presence in groundwater years after application. Organic herbicides that work through physical dehydration leave no synthetic compound in the soil — the naturally derived ingredients break down after the application.

Yes, organic farmers use herbicides, but only naturally derived products that meet strict USDA National Organic Program standards. Synthetic herbicides like glyphosate and 2,4-D are prohibited. Every input used in certified organic operations must appear on the OMRI (Organic Materials Review Institute) approved list or meet equivalent NOP criteria. Organic herbicides work through physical mechanisms like dehydration rather than synthetic chemical disruption, and they break down naturally in the environment without leaving persistent residues.

OMRI — the Organic Materials Review Institute — is an independent nonprofit that reviews and certifies products for use in organic agriculture. An OMRI-listed product has been independently verified to meet USDA National Organic Program standards. This is not a self-declared label — it requires documented formulation review, ingredient sourcing verification, and ongoing compliance monitoring. For farmers and homeowners, OMRI certification is the most reliable indicator that a product is genuinely organic. Salacia is OMRI certified, meaning it meets the same standards required for commercial organic farming operations.

Conventional herbicides use synthetic compounds — laboratory-created molecules like glyphosate, 2,4-D, and dicamba — that disrupt specific biochemical pathways in plants. These compounds can persist in soil for days to weeks and have been documented in waterway contamination studies by the USGS. Organic herbicides use naturally derived ingredients that work through physical mechanisms like dehydration or contact burn. They break down naturally in the environment and leave no synthetic residue in the soil. The trade-off historically was effectiveness — but OMRI-certified selective herbicides like Salacia have closed that gap.

On broadleaf lawn weeds like dandelions, clover, and ground ivy, OMRI-certified selective herbicides deliver comparable results to synthetic products. The mechanism is different — dehydration versus hormone disruption — but the outcome is the same: the weed dies and the grass stays. Where organic products historically fell short was selectivity — every organic herbicide was non-selective, killing grass along with weeds. Salacia solved this as the first OMRI-certified herbicide with true selective action, making organic weed control practical for lawns and turf for the first time.

Organic farmers rely on integrated weed management — a combination of strategies rather than a single product. This includes crop rotation to disrupt weed germination cycles, cover cropping to suppress weed growth through competition, mechanical cultivation and hand weeding, mulching to block light from reaching weed seeds, and flame weeding for targeted thermal control. Organic herbicides are one tool in this integrated approach, used when other methods are insufficient or impractical. The same principles apply to residential lawn care — healthy turf maintenance combined with targeted organic herbicide treatment.

Yes — but only with a selective organic herbicide. Most organic weed killers are non-selective, meaning they burn everything they touch including your grass. Salacia is the first OMRI-certified selective herbicide. It uses osmotic dehydration to target broadleaf weed tissue while narrow grass blades retain enough moisture to recover. The selectivity comes from plant architecture: wide broadleaf leaves absorb more product than vertical grass blades, so the weed dies while the turf stays intact.

Pulling weeds removes the visible plant but almost never extracts the entire root system. Dandelions have taproots that can reach over a foot deep, and perennials like ground ivy spread through underground stolons that fragment when you pull. Every root fragment left behind regenerates into a new plant. Pulling also disturbs the soil surface, exposing buried weed seeds to sunlight and triggering germination. You end up in an endless cycle where each session of pulling creates the conditions for the next round of weeds.

A selective organic herbicide like Salacia controls common broadleaf lawn weeds including dandelions, clover, ground ivy, wild violet, chickweed, henbit, thistle, and bindweed. These are all dicots — plants with wide, flat leaves that absorb more herbicide per unit area than monocot grass blades. Most of these weeds are controlled with a single application. Deep-rooted perennials like thistle or bindweed may require a follow-up application one to two weeks later to exhaust root reserves.

Salacia carries a Pet Friendly designation on its label. The active mechanism is osmotic dehydration — a physical process that draws moisture from plant cells. Animal biology does not respond to this mechanism the same way plant tissue does. There are no synthetic residues left in the soil after application. Always follow product label directions regarding re-entry intervals and application rates to ensure proper use around family members and animals.

A selective herbicide targets specific plant types — in this case, broadleaf weeds — while leaving others unharmed. A non-selective herbicide kills all vegetation it contacts, including grass, flowers, and anything else in the spray zone. Most organic weed killers on the market are non-selective, which is why they destroy lawns along with the weeds. Salacia is the first OMRI-certified organic herbicide that offers selective action, controlled by mixing rate. At the selective rate it targets broadleaf weeds on lawns; at the higher rate it works as a non-selective for hardscape areas.

Yes — on broadleaf weeds like dandelions, clover, ground ivy, wild violet, and chickweed, OMRI-certified organic herbicides deliver effective control. The key is understanding the mechanism: organic herbicides like Salacia work through osmotic dehydration, drawing moisture out of weed tissue until the plant collapses from the leaves down through the crown. This physical mechanism is different from synthetic chemical disruption, but the outcome is the same — the weed dies. Results are most effective when applied during active growth at temperatures between 60 and 80 degrees Fahrenheit.

Most organic weed killers on the market are non-selective — they kill everything they contact, including grass. When homeowners spray these products on their lawn, they kill the weeds AND the surrounding turf, creating bare patches that invite even more weeds. The products work on weeds, but they also destroy the lawn. This is why selectivity matters. Salacia is the first OMRI-certified selective organic herbicide — it targets broadleaf weeds while leaving grass unharmed, solving the fundamental problem that made previous organic options impractical for lawn use.

On common broadleaf lawn weeds, OMRI-certified selective organic herbicides deliver comparable control to synthetic products like those containing 2,4-D or dicamba. The mechanism differs — dehydration versus hormone disruption — but both approaches kill the weed. Where organic products have a significant advantage is in what they leave behind: no synthetic residue in soil, no contribution to waterway contamination, and a Pet Friendly label designation. The trade-off is that organic herbicides are contact-based and require thorough coverage, while some synthetic products are systemic and translocate through the plant vascular system.

OMRI — the Organic Materials Review Institute — is an independent nonprofit that reviews products for compliance with USDA organic standards. An OMRI-certified weed killer has been independently verified to contain only naturally derived ingredients that meet National Organic Program criteria. This is not a self-declared marketing label — it requires documented formulation review, ingredient sourcing verification, and ongoing compliance monitoring. Salacia is OMRI certified, meaning it meets the same standards required for use on certified organic farms.

Organic herbicides that work through dehydration show visible effects on weed tissue relatively quickly after application — leaves begin to wilt and brown as moisture is drawn from the cells. Complete control of the root system takes longer as the dehydration progresses from the leaves down through the crown tissue. Most common broadleaf weeds are fully controlled with one application. Stubborn perennials with deep root systems — like thistle or bindweed — may need a follow-up application one to two weeks later to exhaust the root energy reserves.

Yes. Ants are among the most beneficial organisms in garden soil. Research from university entomology departments confirms that ant tunneling aerates compacted soil, improves water infiltration, and redistributes organic matter throughout the soil profile. A single ant colony can move several tons of soil per acre per year, creating channels that allow roots to access water and nutrients more efficiently. Healthy ant populations are a reliable indicator of a functioning soil ecosystem.

Ants are effective natural predators of many common lawn and garden pests. They feed on flea larvae, termite scouts, caterpillars, and other soft-bodied insects that damage turf and plants. Some ant species also tend aphids for honeydew, but the net effect of ant predation on harmful insects is overwhelmingly positive for lawn health. Eliminating ant colonies with broad-spectrum synthetic chemicals removes this free layer of biological pest control and often leads to secondary pest outbreaks.

Synthetic herbicides disrupt ant colonies through direct toxicity and indirect habitat destruction. Persistent compounds like atrazine and 2,4-D contaminate the soil matrix that ants live in, killing workers and larvae on contact or through ingestion. Even when concentrations are not immediately lethal, they impair ant navigation, foraging behavior, and colony reproduction. Research published in environmental toxicology journals shows that repeated synthetic herbicide applications can reduce soil invertebrate populations by 50 percent or more over several seasons.

OMRI-certified organic herbicides like Salacia work through osmotic dehydration of weed foliage rather than persistent soil chemistry. Because the mechanism targets leaf tissue and breaks down naturally after application, it does not leave synthetic residues in the soil where ants live and forage. This is a fundamental difference from synthetic herbicides that persist in soil for weeks or months. Organic weed control allows you to manage broadleaf weeds while preserving the ant colonies and other soil organisms that keep your lawn ecosystem healthy.

Ants become problematic when colonies build large mounds that disrupt the surface of a lawn, create tripping hazards, or invade structures. Fire ants in southern regions pose a genuine sting risk. However, most common lawn ant species — pavement ants, field ants, and black garden ants — are harmless to humans and beneficial to soil. The instinct to eliminate all ants is counterproductive. A better approach is to tolerate beneficial species and address only the specific colonies causing structural or safety concerns, ideally with targeted methods rather than broadcast synthetic chemicals.

One 25 lb bag of Salacia covers up to 10,000 square feet when used at the standard selective application rate for broadleaf weed control. This is enough for the average American lawn in a single application. For heavy infestations requiring a higher rate, coverage is approximately 5,000 square feet per bag. The exact coverage depends on application method — broadcast spreading covers more evenly, while spot-treatment uses less product per application but requires more precise targeting.

The simplest method is to use a free satellite tool like Google Earth. Find your property, use the measure tool to outline your lawn areas (excluding the house, driveway, garden beds, and other non-lawn surfaces), and the tool will calculate the square footage. Alternatively, you can measure with a tape measure: multiply the length by the width for rectangular sections, then add them together. Most homes with a front and back yard on a standard lot fall between 5,000 and 12,000 square feet of actual lawn.

If your lawn exceeds 10,000 square feet, you have two options. For full broadcast coverage, order a second bag — two bags cover up to 20,000 square feet. However, most homeowners do not need to treat every square foot. Selective spot-treatment of weed-infested areas is often more efficient and uses significantly less product. Identify the areas where weeds are concentrated and treat those zones first. One 25 lb bag goes much further when applied as targeted spot-treatment rather than a full broadcast application.

Yes. Store unused Salacia in its original sealed bag in a cool, dry location away from direct sunlight. A garage shelf or garden shed works well. Keep the bag off the ground and away from moisture. When stored properly, Salacia maintains its effectiveness for the full duration listed on the product label. Reseal the bag tightly after each use — moisture exposure can cause clumping and reduce the product performance.

For most broadleaf weeds, one application is sufficient. For deeply rooted perennial weeds like thistle or wild violet, a follow-up application two to three weeks after the first treatment may be needed to exhaust the root energy reserves. Seasonal reapplication — once in spring and once in early fall — provides year-round control and prevents new weed establishment. At the standard rate, one 25 lb bag provides enough product for two full-lawn applications on a 5,000 sq ft lawn or one full application on a 10,000 sq ft lawn.

The 25 lb size was designed around the average American lawn. According to the National Association of Landscape Professionals, the median lawn size in the United States is approximately 10,000 square feet. A 25 lb bag covers that area in one application — no leftover waste from oversized bags, no running short from undersized ones. It is also a manageable weight for a single person to carry and pour into a spreader. For smaller lawns under 5,000 sq ft, spot-treatment is recommended and one bag will last through multiple application cycles.

Wild strawberries spread through runners that root at every node, making hand-pulling ineffective — you would need to remove every fragment to prevent regrowth. The most effective approach is a selective herbicide that targets the broadleaf strawberry plants while leaving your grass unharmed. Salacia, the first OMRI-certified selective herbicide, controls wild strawberries through osmotic dehydration at its selective mixing rate. Apply directly to the strawberry foliage during active growth in spring or early fall, wetting all leaf surfaces thoroughly.

Most "wild strawberries" in lawns are actually mock strawberry (Duchesnea indica, now Potentilla indica) — an invasive look-alike from Asia. True wild strawberry (Fragaria virginiana) is native to North America and produces small edible berries with flavor. Mock strawberry produces tasteless, upward-pointing berries and has yellow flowers instead of white. Both spread aggressively through runners and are classified as lawn weeds when they invade turf. Both are broadleaf plants that respond to selective herbicide treatment.

Wild strawberries and mock strawberries reproduce through stolons (runners) that create new rooted plants at every node. A single parent plant can produce dozens of daughter plants connected by underground and surface runners. When you pull the visible plant, you leave runner fragments and daughter plants behind — each capable of regenerating into a full plant. Effective control requires either removing the entire runner network (practically impossible in an established infestation) or using a selective herbicide that kills the plant tissue down to the growth point.

Yes. Wild strawberries form dense mats of trifoliate leaves that shade out grass below them. The runners spread horizontally across the lawn surface, rooting at nodes and creating an interlocking network that competes with turf for sunlight, water, and soil nutrients. In shaded or thin lawn areas, wild strawberries can become the dominant ground cover within one or two growing seasons. Early treatment with a selective herbicide — before the runner network becomes extensive — produces the best results and prevents large-scale turf damage.

The best treatment window is early to mid spring (March through May) when wild strawberries are actively growing and producing new runners. A second effective window is early fall (September through October). Apply a selective herbicide on calm mornings with temperatures between 60 and 80 degrees Fahrenheit, with no rain expected for at least 24 hours. Treat before the plants flower and set fruit to prevent seed production and reduce the soil seed bank for the following season.

Thistle is easy to spot once you know what to look for. It has deeply lobed leaves with sharp spines at the tips of each lobe, a stiff upright stem that can reach two to five feet tall, and purple or pink pom-pom-shaped flower heads. Canada thistle (Cirsium arvense) is the most common lawn variety. It grows in rosettes close to the ground in its first year, then sends up tall flowering stalks in its second year. If you see a flat rosette of spiny, grey-green leaves in your turf, that is young thistle establishing itself.

Canada thistle has one of the most extensive root systems of any lawn weed. The primary taproot can reach six feet deep, and the lateral root network extends 15 feet or more horizontally underground. These lateral roots send up new shoots every few inches, which is why a single thistle plant can produce a dense patch covering several square yards within one or two growing seasons. This deep root system also makes hand-pulling ineffective — any fragment of root left behind will regenerate into a new plant.

When you mow over thistle, the plant interprets the removal of its top growth as damage and responds by sending more energy into its root system. The lateral roots then produce additional shoot buds, resulting in more thistle plants than you started with. Each mow cycle triggers another round of compensatory growth. This is why homeowners who try to mow thistle out of their lawn often see the patch double or triple in size within a single season. The correct approach is to kill the root system with a selective herbicide before mowing.

Conventional hand-pulling and digging rarely work because the root system is so extensive that any remaining fragment regrows. However, you can control thistle organically using an OMRI-certified selective herbicide like Salacia. It uses Hybrisal Technology — a dehydration-based mechanism that draws moisture from broadleaf weed tissue while grass retains enough moisture to recover. This is a physical mode of action, not a synthetic chemical one, and it is OMRI-certified organic and labeled Pet Friendly.

The most effective time to treat thistle is in early fall (September through October) when the plant is actively moving nutrients from its leaves down into its root system for winter storage. A selective herbicide applied during this period follows the same downward transport pathway, reaching deep into the root network. Spring treatment (April through May) during the rosette stage — before the plant bolts and sends up flower stalks — is the second-best window. Avoid treating in summer heat above 85 degrees Fahrenheit.

Because the root system is so deep and extensive, a single treatment may not eliminate every root fragment. Plan for one to two follow-up applications spaced two to three weeks apart to exhaust the root energy reserves. Once the root network is depleted, the thistle patch will not regrow from those roots. However, thistle seeds remain viable in soil for up to 20 years, so new seedlings may occasionally appear. Spot-treating these young rosettes early — before they develop a deep root system — prevents reestablishment.

The most common purple-flowering lawn weeds are wild violet, ground ivy (creeping charlie), henbit, and purple deadnettle. Wild violet has heart-shaped leaves and grows in rosettes. Ground ivy has round scalloped leaves and creeps along the ground rooting at every node. Henbit has square stems and pink-purple tubular flowers. Purple deadnettle has triangular leaves that turn reddish-purple near the top. All four are broadleaf weeds that can be controlled with a selective herbicide like Salacia without damaging your grass.

You need a selective herbicide — a product that targets broadleaf weeds while leaving grass unharmed. Most organic weed killers are non-selective, meaning they kill everything including your turf. Salacia is the first OMRI-certified selective herbicide, using Hybrisal Technology to target purple-flowering weeds like wild violet and ground ivy through dehydration while your grass stays intact. Apply directly to the weeds during active growth for the most complete control.

Purple weeds like wild violet and ground ivy are among the most persistent lawn invaders for several reasons. Wild violet has thick, waxy leaves that resist absorption of many herbicides, plus a rhizome root system that regenerates even after the above-ground plant is removed. Ground ivy roots at every node as it creeps across the lawn, so pulling one section leaves dozens of rooted fragments behind. A selective herbicide that works through dehydration bypasses the waxy leaf barrier by drawing moisture directly from the tissue.

Yes, ground ivy and creeping charlie are the same plant — Glechoma hederacea. Other common names include gill-over-the-ground, field balm, and run-away-robin. It is a member of the mint family, which explains its characteristic square stems and aggressive spreading habit. It produces small purple or blue-purple flowers in spring and creates dense mats that smother grass. Selective herbicide treatment during active growth in early spring or fall is the most effective control method.

The best time to treat purple-flowering weeds is during their active growth periods — early spring (March through May) and early fall (September through October). Wild violet and ground ivy are most vulnerable when they are actively photosynthesizing and absorbing product through their leaves. Apply Salacia on calm mornings with temperatures between 60 and 80 degrees Fahrenheit, with no rain expected for at least 24 hours. Henbit and purple deadnettle are cool-season annuals best treated in early spring before they set seed.

Purple deadnettle is a winter annual — it germinates in fall, overwinters as a small plant, then flowers and sets seed in early spring before dying in summer heat. It appears to come back every year because it drops thousands of seeds that germinate the following fall. The key to long-term control is treating it in early spring before it flowers and sets seed, breaking the germination cycle. A selective herbicide applied during the spring growth phase eliminates the current plants and prevents seed production.

Yes. When applied using the crown technique — spraying directly into the center of the dandelion rosette where the leaves meet the root — the product reaches the root system and kills the entire plant. Most organic herbicides only burn leaf tissue, which is why dandelions grow back. Salacia's naturally derived formula dehydrates the weed from the crown down, collapsing the root system that other products cannot reach.

No. At the selective mixing rate, Salacia targets broadleaf weeds like dandelions while leaving your grass unharmed. This makes it the first OMRI-certified selective herbicide — it works like a conventional selective product but is made entirely from naturally derived ingredients. For areas where you want to kill everything (driveways, fence lines), a higher non-selective rate is available from the same product.

Most dandelions require a single application using the crown technique. For heavy infestations or particularly established plants with deep root systems, a second application may be needed. The key is thorough coverage — spray every leaf surface until glistening, then give an extra deliberate dose directly into the crown where all the leaves converge. Proper technique on the first application is more important than multiple light passes.

The crown technique targets the center of the dandelion rosette — the point where all leaves meet the root at ground level. After coating every leaf with product, you give an extra deliberate spray directly into this central crown area, allowing the product to pool and soak down into the root system. This is what separates a surface burn from a complete kill. Standard leaf-only spraying misses the crown, which is why many people see dandelions grow back.

A selective herbicide targets broadleaf weeds like dandelions while leaving grass unharmed. Most organic herbicides are non-selective — they kill everything they touch, including your lawn. Salacia is the first OMRI-certified selective herbicide, meaning it controls dandelions at the selective mixing rate without damaging your turf. The key is applying directly to the weed using the crown technique for complete root kill.

Permanent dandelion control requires killing the taproot, not just burning the leaves. Dandelion taproots can reach 10 to 12 inches deep and regenerate from fragments left in the soil. The crown technique — spraying directly into the center of the dandelion rosette where the leaves meet the root — delivers the product to the root system for a complete kill. Combine targeted treatment with overseeding bare spots and maintaining thick, healthy turf to prevent new dandelions from establishing.

Yes, every part of the dandelion is edible — the leaves, flowers, and roots. Dandelion greens are more nutrient-dense than kale or spinach, delivering over 300% of your daily vitamin A and 600% of vitamin K per cup. Italian families have been cooking with dandelion greens for centuries, and the roots can be roasted into a caffeine-free coffee alternative. The only requirement is that the plants must come from an area that has not been treated with synthetic chemicals.

You can eat dandelions from your lawn only if your lawn has not been treated with synthetic herbicides or chemical fertilizers. Synthetic products leave residues in the soil and on plant tissue that make them unsafe for consumption. If you use an OMRI-certified organic product like Salacia for weed control, your lawn stays free of synthetic chemical residues — meaning you can harvest dandelion greens from untreated areas of your yard for cooking.

Selective herbicides target broadleaf weeds like ragweed while leaving grass unharmed. Salacia is the first OMRI-certified selective herbicide — it uses a naturally derived formula that dehydrates ragweed tissue while your lawn stays untouched.

No. Ragweed has small, green, inconspicuous flowers and fern-like leaves. Goldenrod has bright yellow, showy plumes. Ragweed is wind-pollinated and causes allergies. Goldenrod is insect-pollinated and rarely causes allergic reactions.

Treat ragweed when plants are young — ideally under 6 inches tall in late spring or early summer. Smaller plants are far more vulnerable than mature ones. Apply on warm, dry days with no rain in the forecast.

Yes. Salacia, the first OMRI-certified selective organic herbicide, delivers excellent results on common ragweed. It works through dehydration — a physical mechanism, not a chemical one — and is Pet Friendly.

Common ragweed grows 1 to 3 feet tall with deeply divided, fern-like leaves and hairy, branching stems. Flowers are small, green, and barely visible on spikes at the top of the plant. Upload a photo to Lanaturo Intelligence for a confirmed ID.

Approximately 50 million Americans suffer ragweed allergy symptoms annually. Over 26% of the US population is sensitized to ragweed pollen, making it the most common environmental allergen.

Yes. Common ragweed has developed resistance to glyphosate, ALS inhibitors, and PPO inhibitors — sometimes all three simultaneously. In parts of the Mid-Atlantic, no effective post-emergent chemical herbicide remains for resistant populations.

Salacia Ag is the agricultural application of Hybrisal Technology, currently in development. It provides selective ragweed control in crop settings using an organic mode of action that is entirely different from the chemistries ragweed has developed resistance to.

Climate change is extending ragweed pollen season by 17 to 25 days compared to pre-2010 averages. Rising CO2 levels are also increasing pollen production per plant by 60 to 80%. Every variable is accelerating.

Ragweed-driven allergic rhinitis costs the US healthcare system an estimated $18 billion annually. In agriculture, uncontrolled ragweed causes up to 75% yield loss in corn and soybeans — threatening $112 billion in annual crop receipts.
