How to Get Rid of Crab Grass


All it takes for icky crab grass to take over your lawn is a little bit of ignorance on your part. That’s it. Here you leave one patch of your grass a little too thin, sun-scorched and dried-out, and the next thing you know, the crab grass has take over. 

The botanical name of crab grass is Digitaria and this grass is least attractive with its tough and aggressive make up. It also loves to exploit weak patches and thrives in distressed conditions. And if all that is not stressing enough, this grass also spreads frighteningly fast and in no time can even ruin your real yard.

And then no matter what you try, the crab grass refuses to leave your yard alone.

Now before this nightmare becomes your reality, you must catch hold of the first patch of crab grass you see and then stop it in its tracks. It’s quite easy too.

Let’s learn a little more about crab grass first:

What we need to know about Crab Grass

Crab grass is one of the most troublesome weeds that can take over your yard. Believe it or not, crab grass doesn’t overgrow in our yards overnight. It takes a fair amount of carelessness and negligence on our part for them to attack your yard the way they do. This weed robs your yard of the valuable moisture and nutrients, and makes it look absolutely disheveled and messy.

Even though crab grass is an annual grass, its habits match those of perennial. The growing patterns are indeterminate and it keeps on growing all season long. This is one of the reasons why getting rid of them seems impossible without the right products in hand. But get rid of them, we must. This weed grass is extremely invasive and troublesome. Not only do they destroy our yards, but they are also super stubborn.

Controlling crab grass is even more infuriating, because most home gardeners have a hard time recognizing them. Here are some basic features of crab grass:

  • The leaf blades of crab grass are ¼-inch wide.

  • They have a very thin blade as compared to normal grass.

  • The blades of crab grass sort of grow away and out from the main stem.

Preventing Crab Grass from Taking over Our yards

Once you have dealt with the crab grass, you’ll never want to deal with them again. Which is why, you must do everything in your power to prevent their growth again. Here’s what you can do to keep the paws of crab grass away from your yard:

  • You need to mow your yard frequently, in order to keep their length consistent.   

  • However, you do not need to trim them too close to the soil. They must remain thick and as long as possible without looking overgrown. This will provide shade to the soil as crab grass needs plenty of scorching sunlight in order to germinate.

  • When mowing, make sure you are only removing one-third of the grass blade and no more.

  • Make a habit of watering your yards between long intervals and heavily. Avoid watering it frequently and with shallow water.

  • Also, avoid over watering at all cost. If your grass can handle it then you might even want to skip watering your lawn daily. The more moisture there is, the more crab grass germination there will be.

  • The grass must be fertilized at least once every year.

  • Rake your lawn often, to catch any newly growing crab grass and stop it from spreading its seeds.
