| The best defense against crabgrass is healthy, dense turf. Since crabgrass is an annual, it doesn't overwinter, but the seeds do. So keep your lawn in peak form with proper mowing, feeding and watering, and in the spring, apply a corn-gluten based "weed-n-feed" product (sold under different brand names - if you can't find it, let us know). The corn gluten contains an enzyme that prevents seed germination. If you can prevent the early plants from getting well established, your lawn can compete better early in the season and thicken up before the later crabgrass seeds sprout. Best of luck! |
