One crucial aspect of maintaining a lush, weed-free lawn in the fall is pre-emergent weed control. Apply the first round of pre-emergent weed control in early fall, between September and mid-October, to prevent winter weeds like poa annua and chickweed from establishing. The second application in late fall, between mid-October and late November, will build on this protection and reduce spring weeds, such as crabgrass and dandelions. To manage existing weeds, use post-emergent treatments before winter dormancy. This approach ensures a healthy, weed-free lawn by targeting emerging weeds and supporting pre-emergent efforts, allowing your grass in Texas to thrive without competition for nutrients and sunlight.


The first pre-emergent weed control application should be in early fall.

The first round of pre-emergent weed control should be applied in early fall, typically between September and mid-October. During this period, winter weeds begin to germinate, making it the perfect time to intervene. By applying a pre-emergent treatment early in the season, you create a protective barrier in the soil that prevents newly germinated weeds from surfacing on your lawn.

The goal is to disrupt the life cycle of weeds such as poa annua, henbit, and chickweed before they have a chance to establish themselves. This initial treatment is crucial to lay the groundwork for a weed-free lawn throughout the winter and early spring months.

Late Fall Is the Best Time for the Second Pre-Emergent Weed Control Application

The second pre-emergent weed control application should be applied in late fall, typically between mid-October and late November. This treatment is designed to build off the effects of the first application and provide continued protection against winter weeds. Additionally, it plays a crucial role in drastically reducing the number of spring weeds that surface on your lawn.

Spring weeds, including crabgrass, dandelions, and clover, can be particularly troublesome as they emerge when the weather warms up. A late fall pre-emergent treatment ensures that your lawn remains weed-free well into the spring season, allowing it to thrive without competition for nutrients and sunlight.


Eliminating existing weeds in the fall by using post-emergent weed control treatments.

While pre-emergent treatments are highly effective at preventing new weed growth, there’s still a possibility of existing weeds persisting. For this reason, incorporating post-emergent weed control into your fall routine is essential. Post-emergent treatments are designed to target and eliminate weeds that have already emerged. Applying these treatments as needed before your lawn enters winter dormancy helps ensure that any resilient weeds are dealt with, allowing it to remain strong and healthy. This additional step supports your fall pre-emergent applications by addressing any immediate concerns and optimizing your overall weed control efforts.
