How do I get rid of crabgrass in my yard?
Crabgrass tops America’s list of lawn complaints. The best crabgrass preventer is a healthy, thick lawn, and soil with the proper pH balance (7.0-7.5). Perennial ryegrass is the best competition for crabgrass. It also provides some insect control, as it emits a natural poison that gives some small, damaging bugs the β€œflu.” Fertilizing is key and must be done in the spring and in the fall. Crabgrass thrives in compacted lawns. Aeration can help. A mixture of 1 pint of hydrogen peroxide, diluted to 3 percent, per 100 square feet of lawn can help eradicate the pesky plant. Corn gluten meal, a relatively new and increasingly popular natural herbicide, appears to be successful at preventing crabgrass and other common weeds. A by-product of milling corn, it is completely benign, and in a three-year systematic approach to applying it, it can virtually eliminate crabgrass.
