Like any other weed that can develop in your lawn (broadleaf weeds, grass-like weeds, sedges, etc.), crabgrass will deprive the individual grass plants that make up your beautiful lawn of the things necessary to survive. Nutrients and water that are critical for the survival of your lawn are consumed by weeds. When there is a major breakthrough of weeds, particularly crabgrass, the individual grass plants will die off from starvation or crowding out and the the crabgrass plant will flourish leaving your lawn full of voids and bare spots, particularly after the crabgrass plant has established itself grown in size. The best defense is to prevent this problem before it becomes a major issue affecting the health and appearance of your lawn.

Crabgrass plants germinate from seed when soil temperatures reach approximately 55ºF (approximately April – May). Once germinated, the plant will grow very quickly and as it matures, it will branch out into “tillers”.

You can purchase a bag of a balanced fertilizer WITH crabgrass pre-emergent together in the bag. This will provide a feeding and defend against crabgrass.
