Within a month it will be time to apply a pre-emergent herbicide to the lawn for spring weed control. What you need to know is “how many square feet of lawn you have”. Pre-emergent herbicide does one thing, stops weed seeds from growing. There is no fertilizer in pre-emergent herbicide.
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 comes in a powder and granulated. 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.
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 Lawn Product Application Guides for the application of fertilizers and pre-emergent. We have guides for both Bermuda and St. Augustine lawns. I hope these will fit your need. Please note that these are guides. Weather conditions such as rain and heat will alter the timing of these products.
