It’s time to think about spring weed control here in North Texas. Within a month, it will be time to apply a pre-emergent herbicide to the lawn. The pre-emergent herbicide does one thing and that stops weed seeds from growing. Hence the Latin term “pre”, meaning before. Post-emergent herbicides kill after the plant is growing. Hence, the Latin term “post”, meaning a large stick in the ground that you attach a fence too. You need to determine the square footage of your lawn before heading to Wells Brothers. Also, don’t forget that pre-emergents do not have fertilizer in them.
The synthetic products that Wells Brothers recommends are Gallery for the control of broadleaf weeds and Dimension for the grasses. The 10-pound bag of Gallery will cover 2,000 square feet. This application will last around 4 months. Dimension is available in a 12-pound bag that covers 3,500 square feet and in a 35-pound bag that covers 10,000 square feet. Dimension can be reapplied every 4 weeks.
The all-natural product is called Corn Gluten Meal. It’s available in powder and granulated forms. The powder works faster but is a mess to deal with. The granulated is slower to activate but easier to apply. The application rate for both is 20 pounds per 1,000 square feet and needs to be applied now.
We get asked a lot about applying pre-emergent and fertilizer at the same time. The answer is you apply one then the other. Do not mix them in the spreader at the same time.
