How does pre-emergence weed control work?
Pre-emergence weed control blocks a key enzyme that’s required for growing root cells and prevents weed seeds from continuing their germinating process. Pre-emergent products have no effect on weed plants that are already established, unless the product is combined with an herbicide.
When should I apply it to the lawn?
Homeowners usually apply pre-emergents to lawns at strategic times in the spring and fall. A rough estimate for good application dates would be February 15 and November 15, but the soil temperature must be in the low to mid-50’s. If it is springtime and you have already spotted some weeds sprouting up in the grass, you have waited too long to use pre-emergence weed control products. Time to start pulling or spraying those suckers, at least until fall arrives.
What can I do to make sure the product works?
Try raising your mower blade a little. Longer grass blades have stronger roots and can shade weed seeds enough to prevent them from sprouting. If you use a liquid pre-emergent, allow the product to completely dry before allowing people or pets to walk on the grass. Plan to water the lawn after applying the product; this is necessary for activating the pre-emergent and delivering it to the seeds. Check the product label to make sure it’s safe to use on your type of grass.
Pre-emergence weed control applications are only really necessary twice a year. The product is effective for anywhere from 60 to 110 days after applied. This makes pre-emergents a vital but fairly low-maintenance part of a lawn care regimen. The key is to make sure you are using the right product for your type of grass and that you apply it at just the right time.
