Lawn Weed Identification & Treatment
ChickweedStellaria media
Before Treatment
A cool-season annual forming dense, low mats of small oval leaves with tiny white star-shaped flowers. One of the first weeds to emerge in late winter.
Lawn Safe
Applications
1-2
Mix Rate
3 cups/gal
Selective rate (3 cups/gal). Chickweed forms dense, low-growing mats — get UNDER the canopy. Spray stems, undersides, and soil area around the base. Surface-only spray misses the hidden growth that drives regrowth. Always test a small area of your lawn first before full application.
1-2 applications. Thrives in cool weather — often appears in fall and early spring.
Chickweed is highly responsive to Salacia. Full coverage is still critical — your results are directly proportional to your coverage.
Low-growing mat-forming weed with distinctive three-leaf clusters. Thrives in nitrogen-poor lawns and spreads quickly through runners and seeds.
Lawn Safe
Applications
1-2
Mix Rate
3 cups/gal
Selective rate (3 cups/gal). Clover forms dense mats — get UNDER the canopy, not just the top surface. Spray stems, undersides of leaves, and soil area around the base. The hidden growth underneath is what comes back if you only treat the surface. Always test a small area of your lawn first before full application.
1-2 applications. Regrowth from seed bank is normal — retreat new growth as it appears.
Clover is among the most responsive weeds to Salacia. Full coverage is still critical — your results are directly proportional to your coverage.
A major allergen-producing annual weed that can grow several feet tall. Each plant produces millions of pollen grains per season.
Lawn Safe
Applications
1-2
Mix Rate
3 cups/gal
Selective rate (3 cups/gal). Apply generously to all foliage, stems, and the crown area until runoff. Ragweed can grow tall — make sure to get full coverage on all leaf surfaces and stems. Always test a small area of your lawn first before full application.
1-2 applications. Annual weed — new plants may emerge from seeds throughout the growing season.
Ragweed is a major allergen producer. Treat before it flowers to prevent pollen release. Full coverage on all plant surfaces is the #1 success factor.
The most recognized lawn weed with bright yellow flowers and deep taproots. Spreads rapidly via wind-carried seeds.
Lawn Safe
Crown Pooling
Applications
1-2
Mix Rate
3 cups/gal
Selective rate (3 cups/gal). Crown pooling is essential — spray leaves generously until runoff, then pool/accumulate solution directly in the crown (center rosette). Blanket spraying alone will not control dandelions. Each plant needs that direct crown shot. Always test a small area of your lawn first before full application.
1-2 applications. New dandelions may emerge from the extensive seed bank — this is normal, not a failure. Retreat new rosettes as they appear.
Crown pooling is the #1 success factor for dandelions. Without it, the plant will regrow from the crown even if leaves wilt. Spray leaves AND pool in the crown — every single plant.
A creeping perennial with round, scalloped leaves and a minty smell when crushed. Spreads aggressively via stolons, especially in shady areas.
Lawn Safe
Applications
2-3
Mix Rate
3 cups/gal
Selective rate (3 cups/gal). Ground ivy (creeping charlie) forms dense, spreading mats — get UNDER the canopy. Lift mat edges if needed and spray stems, undersides of leaves, and the soil area beneath. The hidden runners underneath are what drive regrowth if you only treat the surface. Always test a small area of your lawn first before full application.
2-3 applications typical. Ground ivy is aggressive — follow-up treatments as new runners emerge.
Ground ivy is one of the most persistent weeds. Full coverage is absolutely critical — canopy, stems, undersides, soil area. Multiple angles if needed. Your results are directly proportional to your coverage.
A winter annual with square stems, rounded scalloped leaves, and small pink-purple flowers. Covers bare patches in early spring before warm grasses green up.
Lawn Safe
Applications
1-2
Mix Rate
3 cups/gal
Selective rate (3 cups/gal). Henbit forms upright clusters with square stems — spray all foliage, stems, and the soil area around the base until runoff. Get full coverage including lower leaves that hide near the ground. Always test a small area of your lawn first before full application.
1-2 applications. Winter annual — germinates in fall, flowers in early spring. Treat early for best results.
Henbit often appears in dense patches in early spring. Full coverage is critical — do not just mist the tops. Get the stems and lower growth that drive the plant.
A hazardous perennial vine or shrub with distinctive three-leaflet clusters. Its oil (urushiol) causes severe allergic skin reactions in most people upon contact.
Heavy Duty
Applications
1-2
Mix Rate
4 cups/gal
Non-selective rate (4 cups/gal). Apply very generously to all leaves (front and back), stems, and vines. Drench until runoff. Precision targeting to avoid overspray on desirable plants. Always wear full protective clothing.
3+ applications typical. Poison ivy is extremely persistent — repeat treatments as new growth emerges. May require treatment across multiple seasons.
CRITICAL SAFETY: Wear full protective clothing — long sleeves, pants, chemical-resistant gloves, and eye protection. Urushiol oil causes severe allergic reactions. Wash all equipment and clothing thoroughly after use. Do NOT burn poison ivy — smoke carries urushiol and can cause severe respiratory reactions.
A low-growing summer annual forming flat, spreading mats with small oval leaves and milky white sap. Thrives in hot, dry conditions and thin turf areas.
Lawn Safe
Applications
1-2
Mix Rate
3 cups/gal
Selective rate (3 cups/gal). Spurge grows flat against the ground — get UNDER the canopy and spray stems, undersides, and the soil area around the base. Surface-only spray misses the prostrate growth habit. Always test a small area of your lawn first before full application.
1-2 applications. Best controlled when young before it spreads into large mats.
Milky sap may cause skin irritation — wear gloves when handling. Spurge grows flat and tight to the ground, so getting under the canopy is the key challenge.
Wild VioletViola sororia
BeforeAfter
A persistent perennial with heart-shaped leaves and a waxy surface that resists sprays. Thrives in shady, moist areas of the lawn.
Lawn Safe
Applications
2-3
Mix Rate
3 cups/gal
Selective rate (3 cups/gal). Wild violet has waxy leaves — product can bead off the surface. Thorough drenching coverage is critical. Get the undersides of leaves where the wax coating is thinner. Spray stems and soil area around the crown. Always test a small area of your lawn first before full application.
The waxy leaf surface is the main challenge. Do not mist — drench. Get undersides where wax is thinner. Your results are directly proportional to your coverage.
A twining vine that wraps around fences and plants, spreading aggressively through deep roots that can extend over 20 feet underground.
Lawn Safe
Applications
1-2
Mix Rate
3 cups/gal
Selective rate (3 cups/gal). Trace vines back to the base and spray the entire length — leaves, stems, and crown. Bindweed tangles through grass, so targeted application preserving surrounding turf is important. Always test a small area of your lawn first before full application.
1-2 applications with follow-ups as needed. Deep root system means persistence may be required for complete control.
Bindweed has an extensive deep root system. Trace every vine back to the base — the crown and root zone are where regrowth originates. Full coverage along the entire vine is critical.
Broadleaf PlantainPlantago major
BeforeAfter
A tough rosette-forming perennial with broad, ribbed leaves. Tolerates compacted soil and heavy foot traffic where grass struggles.
Precision Required
Crown Pooling
Applications
2-3+
Mix Rate
4 cups/gal
Non-selective rate (4 cups/gal) with surgical precision. Treat as EARLY as possible — young plantain is much easier to kill. Once it matures, the crown hardens and control becomes significantly harder. Soak every leaf top and bottom, every stem, and pool product into the crown until it drips off. If it's not dripping, you haven't used enough. Target only the weed to protect surrounding grass. Mow first for better penetration. Always test a small area first.
2-3+ applications typical. Plantain is one of the toughest broadleaf weeds — patience and persistence are required.
Plantain is the toughest broadleaf weed you'll face. Early treatment is critical — a young plantain is a dead plantain, but a mature one fights back hard. Light spraying does nothing — if it's not dripping off the leaves, add more. Crown pooling is critical: pool product at the base where the leaves meet the root. Multiple heavy, precise applications are the norm. Be patient, be aggressive, and don't hold back on product.
CrabgrassDigitaria sanguinalis
BeforeAfter
An aggressive annual grass that forms flat, spreading clumps in thin or stressed turf. Thrives in hot summer conditions.
Precision Required
Applications
1-3
Mix Rate
4 cups/gal
Non-selective rate (4 cups/gal) with heavy volume. Salacia CAN kill crabgrass, but ONLY at the non-selective rate — this WILL damage surrounding lawn grass. Best suited for dense crabgrass patches where you can drench the entire area and reseed afterward. NOT practical for scattered crabgrass spread through the lawn — you would damage too much grass chasing individual plants. For dense patches: soak all foliage, stems, crown, and soil area until runoff. Plan to overseed the treated area once the crabgrass is dead.
1-3 applications depending on maturity. Dense patches may need retreatment as new shoots emerge from seeds in the soil. Overseed treated areas to fill in.
Crabgrass is a grass — Salacia cannot distinguish it from lawn grass. The non-selective rate needed to kill crabgrass WILL damage surrounding turf. Only practical for dense patches you can target as a whole area, not for scattered individual plants in a lawn.
Creeping ButtercupRanunculus repens
Before Treatment
A perennial with glossy yellow flowers and three-lobed leaves. Spreads rapidly through above-ground runners, especially in wet, poorly drained areas.
Lawn Safe
Applications
1-2
Mix Rate
3 cups/gal
Selective rate (3 cups/gal). Creeping buttercup spreads via stolons (runners) — trace runners and spray all leaves, stems, stolons, and the soil area around each rooting point. Get UNDER the leaf canopy for full coverage. Always test a small area of your lawn first before full application.
1-2 applications. Spreads via stolons that root at nodes — treat the full connected network.
Creeping buttercup spreads via above-ground stolons that root at each node. Every runner and rooting point needs treatment — missing connected plants allows the network to regenerate. Note: buttercup sap can cause mild skin irritation — wear gloves.
Creeping Tick TrefoilDesmodium rotundifolium
Before Treatment
A low-growing perennial legume with trailing hairy stems that creeps along the ground, forming dense mats in lawns. Produces sticky segmented seedpods that cling to clothing and animal fur.
Lawn Safe
Applications
1-2
Mix Rate
3 cups/gal
Selective rate (3 cups/gal). Tick trefoil forms dense trailing mats — get UNDER the canopy, not just the top surface. Spray stems, undersides of leaves, and soil area around the base. The hidden growth underneath is what comes back if you only treat the surface. Always test a small area of your lawn first before full application.
1-2 applications. Regrowth from seed bank is normal — retreat new growth as it appears.
Trailing stems root at nodes where they contact soil — trace runners back to origin points and spray thoroughly. Sticky seedpods spread via mower decks, clothing, and pets, so treat before pods form to prevent spread.
Field BurrweedSoliva sessilis
Before Treatment
A low-growing winter annual with finely divided, carrot-like leaves and small spiny burs that are painful to bare feet and pets. Thrives in thin, warm-season turf.
Lawn Safe
Applications
1-2
Mix Rate
3 cups/gal
Selective rate (3 cups/gal). Burrweed forms low, flat mats close to the ground — get UNDER the canopy. Spray all foliage, stems, and the soil area around the base until runoff. Treat early in winter or early spring before the spine-tipped burs form. Once burs are present, seeds are already set. Always test a small area of your lawn first before full application.
1-2 applications. Winter annual — germinates in fall, matures in spring. Treat as early as possible for best results. New plants emerge from seeds each fall.
Timing is everything with burrweed. The plant is small and easy to kill in winter, but by spring it produces sharp spine-tipped burs that are painful to step on. Treat before burs form. The mat-forming habit means you need full coverage underneath — light surface spray will miss hidden growth.
Fig ButtercupFicaria verna
BeforeAfter
An early-spring perennial with glossy, heart-shaped leaves and bright yellow flowers. Spreads via underground tubers and bulbils.
Lawn Safe
Applications
2-3
Mix Rate
3 cups/gal
Selective rate (3 cups/gal). Lesser celandine has glossy, heart-shaped leaves — the glossy surface can cause product to bead off. Drench thoroughly to overcome the waxy coating. Spray all leaves, stems, and the soil area around bulbils/tubers. Always test a small area of your lawn first before full application.
2-3 applications typical. Reproduces via underground bulbils and tubers — persistence is key.
Lesser celandine reproduces via underground bulbils that survive surface treatment. Multiple applications targeting both foliage and the soil/crown area are essential. Glossy leaves require drenching, not misting.

DallisgrassPaspalum dilatatum
Photo Coming Soon
A clump-forming warm-season perennial grass with coarse, wide blades and distinctive seed heads. Spreads via short rhizomes and seeds, forming unsightly patches in lawns.
Precision Required
Applications
2-3
Mix Rate
4 cups/gal
NOT recommended in lawns. Salacia can kill dallisgrass, but only at the non-selective rate (4 cups/gal) with heavy volume — this will damage your lawn grass too. For dallisgrass in lawns, the best organic approach is hand-pulling (get the full root clump), overseeding to crowd it out, and maintaining proper mowing height.
2-3 applications likely needed. Deep, clumping root system means persistence is required. Retreat any regrowth aggressively.
