Crabgrass (Digitaria) is a genus of plants in the grass family and it is native to regions with warmer temperatures. It is known to be a grassy weed that sprouts in thin patches of grass or in dried-out lawns. Even though it is a nasty weed that nobody likes, it only lasts one growing season. However, in that one growing season the plant spreads thousands of seeds that sprout very quickly so if it is not treated properly it can potentially take over the yard. This article will give you some tips on how to get rid of the crabgrass growing in your lawn.
Killing crabgrass:
Herbicides that kill crabgrass can potentially kill desirable grass like bluegrass or fescue. That is why it is important to always read the labels on the products that are being used to kill the weed. There is also the option of just pulling the plant out of the yard, but this works best when the plant is young because it will only leave a small hole that desirable grass would quickly fill in. If you notice that the crabgrass’ seed heads are present but still folded up tightly against the plant then that is okay to pull too, but if the seed heads have opened and spread out it is not recommended to pull the weed because it could spread more seeds over the lawn and in the hole that was created when the plant was ripped out.
Preventing crabgrass from growing:
Mowing your lawn has a big impact on how crabgrass goes. You want to mow your lawn to the proper height depending on the type of grass you have. Higher grass shades the surrounding soil which prevents the germination of any crabgrass seeds. The way your lawn is watered also affects the way the weed grows. Infrequent/shallow watering can actually weaken the roots of your grass which would make it easier for the crabgrass to grow. Watering your lawn deeply and less frequently will keep the roots strong and will prevent weeds from sprouting.
Another easy way to help prevent crabgrass from growing is to use a preemergent. This is just a product that inhibits crabgrass seedlings from growing, and it can come in chemical and even natural products. If a crabgrass plant is pulled out from a lawn and it leaves a large area of uncovered soil, some seeds may fall off and end up sprouting again if you are not careful. It is best to reseed the patch with the desired grass seeds quickly after pulling. The perfect time to do this is in the Fall because it will have time to establish itself before Winter, so when Spring rolls around there will be nice, healthy grass growing where a weed once did.
