In this post, am going to share with you practical tips on how to get rid of crabgrass in lawn for good.

Pre-emergent Control

One of the easiest way of controlling the spread of crabgrass is controlling them before they even germinate.

Since there are thousands of dormant crabgrass seeds in your lawn soil waiting for the right season to germinate, you can use pre-emergent herbicides when preparing your lawn to prevent them from germinating.

Crabgrass seeds germinates during early spring when soil temperatures are 55 degrees high and they can continue germinating until late summer.

Therefore, you need a garden thermometer to regularly check the soil temperatures so that you can apply the pre-emergent herbicides at the right time for the best results.

Pre-emergent herbicides will inhibit seed germination as well as root development of crabgrass seeds and you will have less of them in your lawn.

Ensure that you use the right pre-emergent herbicide and follow instructions for use carefully to avoid any unintended damage to your lawn grass seeds.

  • Mesotrione, a potent herbicide, immediately absorbs and starts working upon application, yet it may take 2-3 weeks for full weed death. Activation requires water; if no rainfall occurs within 10 days, apply 0.15 inches of water.
  • Targeting 46 broadleaf species and grasses, including Barnyard grass, Carpetweed, Chickweed, Clover, Crabgrass, and Dandelion, Mesotrione is versatile.
  • Suitable for Kentucky Bluegrass, Centipede grass, Buffalo grass, Tall Fescue, Perennial Ryegrass, Fine Fescue, and St. Augustine Grass (sod only). Avoid Bentgrass, Poa annua, kikuyugrass, zoysiagrass, seashore paspalum, and bermudagrass. Apply Mesotrione on dormant bermudagrass to eliminate weeds.
  • Mesotrione inhibits photosynthesis in susceptible plants, distributing throughout the plant via roots and leaves. It’s an effective herbicide preventing crabgrass seed germination and eliminating broadleaf weeds on contact, encouraging the growth of certain cool-season turfgrass in a weed-free environment.
