Lawn Care: How Pre-emergents work


February 08, 2020


Pre-emergents are used primarily in the winter and early spring to prevent weeds and other unwanted plants from growing in your lawn. Although it is something that almost every weed control and fertilization company provides, do you know why we do it?

Pre-mergent herbicides create a chemical barrier at the top layer of the soil that coats seeds and prevents them from growing roots. A pre-emergent can work on any type of lawn weed, however crabgrass is usually the primary target.

At Green Lawn we formulate the best mixture of pre-emergent based on the type of weeds you have or are prone to having in your lawn. Each lawn may be a little different due to the landscape of the lawn and the types of weeds that are common in that lawn.

Types of Pre-emergents

Keep in mind that no pre-emergent herbicides are able to target all varieties of weeds. Some pre-emergent herbicides kill a broad array of common lawn weeds while others target specific weeds like crabgrass or chickweed.

In addition to targeting different types of weeds, there are also different physical forms of pre-emergent. You will find a granular and a liquid pre-emergent. The liquid form requires a sprayer and water to mix with it. The granular form can be spread by hand or a spreader.

When to Apply Pre-Emergent

Apply pre-emergent herbicide in the spring, a few weeks before weeds typically appear. However, here in the Rockwall area, we can get 70 degree weather in January or February and that is enough to get the weeds to pop up. It doesn’t take much and therefore, we try to be more pro-active in our area.

Pre-emergents can really help prevent your lawn from an onslaught of weeds at the beginning of spring. The less weeds the more resources that are left for your lawn, which ultimately leads to a healthier lawn, not to mention a better looking lawn.
