Crabgrass is a common type of weed that often grows in lawns and gardens. It thrives in warm weather and can spread quickly, forming dense patches that compete with desirable plants for nutrients and water. This annual grass typically germinates in spring and can be identified by its wide, flat leaves and sprawling growth habit. Controlling crabgrass can be challenging, but there are several methods to manage it. Regular mowing, maintaining healthy soil, and using pre-emergent herbicides can help prevent its growth. Additionally, keeping your lawn well-watered and fertilized encourages the growth of desirable grasses, making it harder for crabgrass to take hold.
