Pre-emergent Control

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.
