Crab-grass settled on your lawn?

What Is Crab-Grass?

If you have been fighting off weeds for a while, you probably have already had the chance (or the misfortune) to get acquainted with crab-grass. Crab-grass is a highly invasive weed with a knack for residential lawns.

Seed germination generally occurs at the end of spring and the weed spends the first few weeks of its life unnoticed, looking very similar to young light green grass blades. However, its branches turn purplish as it reaches maturity in August. This is when the situation can get worse.

A Weed Unlike any Other

Crab-grass is a troublesome weed that takes advantage of summer drought to greedily absorb nutrients otherwise meant to feed your lawn.

The bright side (if we may say so), is that it’s also a grass plant as you would find in your lawn. In other words, crab-grass and the plants in your lawn belong to the same plant family. This explains why it is more difficult to eliminate than other weeds: regular treatments for broad leaf weeds have no effect on crab-grass. Other methods need to be applied to successfully eliminate it.

How to Get Rid of Crab-Grass?

Methods to eliminate crab-grass are limited to a few. Here is some advice from our Nutrite Experts:

1- In spring: examine your lawn

First, take some time early on to examine your lawn. If you spot young crab-grass, it is safe to pull it out. To stem its proliferation at this stage is surprisingly effective. However, make sure it has not yet grown to 3–4 rows of leaves. This would mean seeds have already developed. Therefore, pulling it out at this stage could have the opposite effect.

2- In August: avoid spreading the seeds

In August, when mowing the lawn, we recommend avoiding grasscylcing and using a lawn mower with a rear bag to collect grass clippings. Otherwise, as you spread the clippings, you would spread crab-grass seeds all over your yard, becoming the instrument to seed proliferation.

3- In the fall, aerate, top dress, and reseed

In the fall, it’s time to aerate the soil, add topdressing material, and reseed bare lawn spots. Crab-grass loves those exposed areas in your lawn; this is often where it will establish itself in the first place. You simply need to repair those damaged areas after the summer droughts to leave no room for crab-grass to grow.
