Crabgrass is an annual that grows from seed each year and the best way to control it is with a pre-emergent herbicide. You put this on the lawn before the crabgrass sprouts in the spring and it keeps the seed from germinating. So the timing of application is very important. For the most precise information on timing, contact your local Cooperative Extension Service; here's the URL to a link to help you find the one in your area:http://www.csrees.usda.gov/Extension/index.html. A general rule is to put down crabgrass control when the dogwoods and azaleas are blooming. |
