Ortho WeedClear Weed Killer for Lawns Concentrate
This concentrate is designed to kill more than 250 listed weeds down to the root without harming a healthy lawn when used as directed. It is best for actively growing weeds and larger lawns due to its high coverage capability. Dilute with water according to label directions and apply with a tank sprayer or the Ortho Dial N Spray hose-end sprayer. It covers up to 64,000 square feet per gallon, making it a strong option for bigger yards. A limitation is temperature guidance—avoid applying when daytime temps exceed 90°F, as heat can affect efficacy and turf safety.

This 3-count kit combines weed control with lawn feeding, delivering 20% nitrogen to support turf vigor while targeting major broadleaf weeds such as dandelion, chickweed, clover, and plantain. It is a practical choice for homeowners who want to simplify lawn care by stacking fertilizer and weed control in a single application. Best for small to mid-sized lawns where intake of nitrogen is desired alongside broadleaf weed suppression. A potential limitation is that results depend on proper application timing and weed visibility; follow label directions for best results.
GORDON’S Tankables Weed & Feed 15-0-0
Gordon’s Tankables combines weed control with green-up benefits for lawns and pastures. One bottle treats up to 15–20 thousand square feet, depending on use region and lawn type. It is particularly suitable for larger lawns and mixed habitats where both turf management and weed suppression are needed. Best for users seeking a cost-effective, bulk option with broadleaf weed control. A caution: pastures may require different grazing considerations after application, so review label guidance if animals share treated areas.
Ortho WeedClear Lawn Weed Killer Concentrate
This Ortho concentrate kills listed lawn weeds down to the root and is fast-acting with just one application in many cases. It is best for homeowners who prefer a sprayable concentrate and quick results. Use dilution per label directions and apply with a tank sprayer or the Ortho Dial N Spray for best coverage. A limitation to note is that effectiveness depends on weed type and growth stage; some stubborn perennials might require follow-up treatments under label guidance.
Scotts Liquid Turf Builder with Plus 2 Weed Control
Scotts combines a quick nitrogen boost with broadleaf weed control in a ready-to-spray formula. This is ideal for homeowners who want a convenient hose-end application that simultaneously fertilizes and suppresses common lawn weeds. Best used on actively growing weeds for fastest results. The main caveat is that it targets broadleaf weeds and some grasses may be sensitive to nitrogen-rich formulations; apply according to label directions to avoid turf burn or over-fertilization.
Roundup For Lawns₂ Concentrate
Roundup For Lawns₂ Concentrate is designed for northern grasses and claims robust weed control, including crabgrass, dandelion, clover, and others. It emphasizes root-kill with selective use and provides up to three months of weed suppression in some cases.

A caution is to follow all label directions precisely to protect sensitive turf species and to ensure safe application timing, especially in cooler seasons when grasses are stressed.

It is formulated to kill weeds with minimal lawn damage when used as directed, offering visible results within hours. It suits homeowners with sizable turf areas needing broad-spectrum control.

Choose this if you already have the AccuShot applicator and want a broad-spectrum solution. A limitation is that very stubborn perennials may need multiple applications for complete control.
Buying Guide: Key Considerations For Choosing A Weed And Feed Concentrate
- Weed profile: Identify the major weeds in your lawn. If dandelion and clover are prevalent, select products known to target those broadleaf weeds.
- Lawn size and coverage: Check the product’s coverage per bottle or per gallon and match it to your yard’s square footage.
- Turf type and climate: Some formulas are better suited for northern grasses or warm-season turf. Consider seasonal temperatures and the risk of turf burn.
- Application method: Sprayer-compatible concentrates require mixing; ready-to-use hose-end options offer convenience but may have different coverage rates.
- Nitrogen and feeding plan: Weed-friendly fertilizers help promote healthy turf, but over-fertilization can stress the lawn. Balance weed control with a feeding strategy.
- Safety and timing: Always read and follow label directions, including watering schedules, reentry intervals, and grazing restrictions if applicable.
