March is the time
March is the time to apply preemergence if crabgrass or weeds were a problem in your yard last season. Use a preemergence herbicide or “Crabgrass Preventer” now before weeds and grassy weeds start germinating. Temperatures are very warm this March and lawns are greening up. This means weeds and grassy weeds will be showing up soon.
How it works.
Crabgrass preventers stop most weed and grassy weed seeds from germinating. These products keep all the unwanted seeds that end up in your yard from sprouting. Most of these products last 6 to 8 weeks, so a second application is recommended in May, especially if your yard has a history of various weed problems. After you apply this granular product with a fertilizer spreader, water it in to your yard within a day. If you have not turned on your sprinkler system, use a hose and water in by hand or apply before we get some precipitation. A quick application of Crabgrass control will cut down on spring lawn care and let you enjoy your lawn this spring!
