How to Tackle Common Lawn Weeds
Getting rid of dandelion, crabgrass, and other ugly weeds in your yard can be faster and easy than you think.
Some things are meant to take extra time. Getting rid of lawn weeds shouldn’t be one of them. For fast, effective weed control (think sprint, not marathon), all it takes is a little know-how. To that end, here’s a look at the most common and annoying lawn weeds, along with tips on how to kill each and every one.
What Is Chickweed?
Chickweed is a low, spreading annual weed that looks, smells, and tastes like an herb (it’s edible), which means it attracts insect pests like spider mites and thrips.
Tips for Killing Chickweed
- Apply fast-acting Ortho® WeedClear™ Lawn Weed Killer Ready-to-Spray* to kill chickweed to the root without harming your lawn when used as directed.
- Mow higher, especially in the fall when chickweed germinates.
- Water your lawn only as needed since chickweed thrives in super-moist conditions.
- Follow package directions when applying fertilizer to your lawn. Overapply and the extra nitrogen can lead to explosive chickweed growth.
What Is Clover?
Clover is a low-growing weed most recognizable for its cluster of white and pink-tinged flowers.
Tips for Killing Clover
- Spray large patches of clover with Ortho® WeedClear™ Lawn Weed Killer Ready-to-Use with Comfort Wand*. The battery-powered trigger sprayer lets you spray continuously with ease.
- Maintain healthy, thick turf by feeding your lawn regularly.
- Mow your lawn regularly, too, and at the right height for your grass type.
- Repair any bare spots to help keep new weeds from taking up residence.
What Is Crabgrass?
Crabgrass is a fast-growing, heat-tolerant, grassy weed that forms a crab-like cluster and produces thousands upon thousands of seeds.
Tips for Killing Crabgrass
- Apply Ortho® WeedClear™ Lawn Weed Killer Ready-to-Spray* when you first notice crabgrass in the spring. For dense infestations, apply a second time 3 weeks after the first application.
- Maintain a thick, vigorous lawn to keep crabgrass seeds from getting the sunlight they need to grow.
- Keep mower blades sharp so grass recovers quickly and stays healthy.
- Water deeply yet infrequently since crabgrass prefers the exact opposite: shallow, frequent watering.
What Is Dandelion?
Dandelion is a flat-growing, perennial weed with a deep taproot and a bright-yellow flower that fades to a puffball.
Tips for Killing Dandelion
- Spray actively growing dandelion leaves with Ortho® WeedClear™ Lawn Weed Killer Ready-to-Use with Comfort Wand®*. It works its way through the weed to kill all the way down to the root when used as directed.
- Mow high, taking off only about one-third of the length of the blade each time.

- Overseed your lawn in the fall to help thicken it up and crowd out dandelion.
What Is Dollarweed?
Dollarweed, also known as pennywort, is a broadleaf lawn weed with leaves that look like tiny lily pads and a stem that grows directly from the center of the leaf.
Tips for Killing Dollarweed
- Spray Ortho® WeedClear™ Lawn Weed Killer Ready-to-Use with Comfort Wand®* lightly to cover dollarweed leaves. This fast-acting formula works best when weeds are young and actively growing.
- Avoid over-watering your lawn because dollarweed thrives in moist environments. Instead, aim for about an inch of water a week.

- Limit access to sunlight with healthy, dense turfgrass that crowds out oxalis.

What Is Plantain?
Plantain is a perennial weed with short, thick tap roots, and leaves that form a rosette shape.
Tips for Killing Plantain
- Treat a plantain problem with Ortho® WeedClear™ Lawn Weed Killer Ready-to-Spray*. With this fast-acting formula, you’ll see results in just one application when used as directed.
