How to Get Rid of Crabgrass
Crabgrass is a weed that can take over your yard. Here is an easy plan to stop it and keep your grass green.
What crabgrass is
Crabgrass is a weed that grows low and spreads out wide, kind of like a crab’s legs. It pops up in spring when the soil starts to warm up. The plant only lives for one year and dies when it gets cold. But before it dies, one plant can drop thousands of seeds. Those seeds wait in the dirt and grow the next spring, so the problem comes back again and again.
Stop it before it starts
The smartest way to beat crabgrass is to stop the seeds from ever growing. You do this with a product called a pre-emergent. It makes a shield in the soil that keeps seeds from sprouting. Spread it in early spring, before the ground warms past about 65 degrees. Timing matters a lot. Put it down too late and the seeds will already be growing.
Pull it or spray it while young
If a few crabgrass plants slip through, act fast while they are small. Pulling works great after rain, when the dirt is soft. Grab low and pull slowly to get the whole root. If you see seed heads that spread out like a fork, leave the plant alone, because pulling it would just scatter more seeds. For young plants, you can also use a post-emergent spray made to kill weeds without hurting your grass.
Grow a thick, strong lawn
The best weed fighter is healthy grass. When your lawn is thick, crabgrass has no open space and no sunlight to grow. Mow your grass a little tall so it shades the soil, and water it well. Fill in any bare or thin spots with new grass seed in the fall. Feed the lawn through the year too. A full, happy lawn crowds crabgrass out all on its own.
