Within a month, it will be time to start applying pre-emergent herbicide to your lawn. Pre-emergent herbicides do one thing and that’s to stop weed seeds from growing. Hence the Latin term “pre,” means before. Post-emergent herbicides kill after the plant is growing, hence, the Latin term “post”, means a large stick in the ground that you attach to a fence. I urge everyone to know the square footage of your lawn before heading to Wells Brothers. Also, don’t forget that pre-emergent is not fertilizer.
The synthetic pre-emergent products that Wells Brothers recommend are Gallery for the control of broadleaf weeds and Dimension for the grass weeds. 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 pelleted forms. The powder works faster but is a mess to deal with. The pelleted 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.
Check out the Wells Brothers easy-to-read schedule for the application of fertilizers and pre-emergent. I hope these will fit your needs. Please note that these are guides. Weather conditions such as rain and heat will alter the timing of these products.
