How do you get rid of crab grass?

Question

Without tearing up your lawn.

Answer 1

You can buy a post-emergent (already grown) crabgrass killer from pretty much any place that sell lawn care chemicals. The one I use is Bayer's All in one advanced. However, depending on where you live, it will start to die naturally in a few weeks. Crabgrass will die when the night time temperatures stay consistently under 55 degrees. That will just be a few weeks off. Next year make sure you put down a crabgrass preventer, maybe two apps. First one late Feb/early march. The second in mid to late april. Be wary of how much you water during hot season. Crabgrass preventors work on a residual basis. The protective residue will break down with watering (otherwise fall seedings will fail too). So if you water heavy during hot summer to prevent from going brown you will increase the rate your protection breaks down. So if it starts to turn brown, just accept it will happen and water about half as much just to make sure the roots stay alive. Once the temps come back down so will your color.

Answer 2

Here's what I do.
Crab Grass is usually RIGHT UNDER where the Lawn Mower gets so it actually never gets cut. Pull up the crab grass by hand (unfortunately it's the best means without chemicals - some checmicals will ruin your grass too.) Grass that was underneath the crab grass will be yellow, so you will have yellow spots wherever you removed the Crab Grass.
Use those shoes to Aerate the soil and plant new grass seeds. Water EVERY day until the new grass comes up and you'll have renewed your lawn.

Answer 3

Crab grass grows later than regular grass, and dies sooner, leaving patches. First thing in the spring, there is a certain lawn treatment you can get at a lawn and garden store, if you apply it to the lawn before the crab grass starts growing, it will inhibit it. Also, it is important to take care of your lawn, so that the regular grass fills in the spots where the crab grass was, and takes root.
