The Best Pre-Emergents for Turf-Type Tall Fescue Lawns in Virginia: A March Prep Guide

Maintaining a lush, green turf-type tall fescue lawn in Virginia requires proactive care, especially when it comes to preventing weeds. One of the most effective strategies is the application of pre-emergent herbicides. 

A pre-emergent, like a crabgrass preventer, creates a barrier that inhibits the germination of weed seeds, ensuring your lawn remains healthy and vibrant all season long.

Why March is the Best Time to Apply Pre-Emergents

Pre-emergent herbicides are chemicals designed to prevent the germination of weed seeds. They are typically applied in early spring and, in some cases, again in the fall. For turf-type tall fescue lawns in Virginia, applying a pre-emergent herbicide, like a crabgrass preventer, in March is crucial to control common weeds such as crabgrass and other annual grasses.

In Virginia, particularly in the Hampton Roads area, March marks the transition from winter to spring. Soil temperatures begin to rise, signaling the start of weed seed germination. By applying a pre-emergent herbicide during this period, you ensure that the herbicide is active in the soil when weeds attempt to sprout.

Selecting the Right Pre-Emergent Herbicide

When selecting a pre-emergent herbicide, it’s important to choose a product specifically formulated for turf-type tall fescue lawns and suited to Virginia’s climate. Key factors to consider include the types of weeds the herbicide targets, whether it’s best applied in granular or liquid form, and its compatibility with your lawn care routine.   

At Taylor’s, we love to recommend Scotts and Jonathan Green as great pre-emergent brands. Both brands offer high-quality pre-emergent herbicides designed to stop crabgrass before it takes root, ensuring a healthier and more vibrant lawn throughout the growing season.

Application Tips and Consideration

When applying pre-emergent herbicides to your turf-type tall fescue lawn, there are several important tips to follow to achieve the most effective results. First, monitor soil temperatures using a soil thermometer, and aim to apply the pre-emergent when the soil consistently reaches 55°F for several consecutive days. Ensure even distribution of the herbicide by using a broadcast spreader to achieve uniform coverage across your lawn. 

After application, water your lawn thoroughly to activate the herbicide and help it penetrate the soil. Avoid disturbing the soil by refraining from aerating or dethatching immediately after applying the pre-emergent, as this can disrupt the herbicide barrier.

Keep in mind that while pre-emergents prevent new weeds from germinating, they won’t eliminate existing ones, so consider using a post-emergent herbicide for weeds that have already emerged. Finally, stay aware of local weather conditions—especially in Hampton Roads where coastal influences can affect soil temperatures and moisture levels—so you can time your application effectively.

Applying a pre-emergent herbicide in March is a vital step in maintaining a healthy, weed-free turf-type tall fescue lawn in Virginia. At Taylor's, we offer a variety of pre-emergent herbicides tailored to local conditions, helping you achieve the best results for your lawn. Stop by your neighborhood Taylor’s Do it Center today!
