Why October is the Perfect Time for Pre-Emergent Weed Control

As the crisp fall air settles in and the leaves begin to turn, many homeowners shift their focus away from lawn care, thinking the work is done for the season. However, October is one of the most crucial times to take action against one of your lawn’s biggest enemies: weeds. Pre-emergent weed control, applied now, can make a significant difference in maintaining a healthy, vibrant lawn when spring arrives.

What is Pre-Emergent Weed Control?

Pre-emergent weed control involves applying a specialized herbicide designed to target weed seeds before they have a chance to germinate. Unlike post-emergent herbicides, which kill weeds after they’ve sprouted, pre-emergents create a protective barrier in the soil that stops weed growth in its tracks. This method is particularly effective for combating common winter and spring weeds like crabgrass, poa annua (annual bluegrass), and henbit.

Why October is Ideal for Application

October is the sweet spot for applying pre-emergent weed control in Shreveport and the surrounding areas. Here's why:

1. Soil Temperature: Many weed seeds begin to germinate when soil temperatures fall between 55°F and 70°F, which typically happens in early fall. Applying a pre-emergent now ensures that the herbicide is in place before these seeds can sprout.
2. Winter Weeds are Waiting: Even though your lawn may look weed-free at the moment, many weed seeds are lying dormant, waiting for cooler temperatures to emerge. Winter annuals like chickweed and annual bluegrass thrive in the fall and winter. Applying pre-emergent herbicides now stops these pesky plants from ever making an appearance.
3. Prepare for Spring: Weeds that germinate in the fall will lie in wait through the winter, ready to grow rapidly in spring. By using a pre-emergent treatment now, you prevent these seeds from developing, meaning fewer weeds to deal with when the weather warms up.

How Pre-Emergent Weed Control Works

When pre-emergent herbicides are applied, they form a chemical barrier on the surface of the soil. As weed seeds start to germinate, they are unable to break through this barrier and are stopped from growing. It’s important to remember that pre-emergents won’t kill existing weeds, so now is the time to treat bare or weed-covered spots with a post-emergent treatment first, then follow up with pre-emergent care.

Tips for Effective Pre-Emergent Application

To get the most out of your pre-emergent weed control, follow these tips:

• Timing is Key: Apply pre-emergents before the first frost and before soil temperatures consistently drop below 55°F.
• Water it In: After applying the herbicide, water your lawn to help activate the treatment. This helps it penetrate the soil and form that crucial barrier.
• Proper Coverage: Make sure to evenly distribute the pre-emergent across your lawn to ensure maximum coverage. Spotty application can leave areas vulnerable to weed growth.
