my lawn is full of crabgrass and weeds. There is so much more than ever before. We used weed and feed in the spring, but this summer the lawn is a mess. What can we do
To treat for crabgrass, you need to use a well-timed application of crabgrass PREVENTER to stop it from starting. Killing crabgrass once it is up is nearly impossible. More on using crabgrass preventer HERE. Later in late spring (or better yet in September) it is the best time for weed killer. More on properly using weed killer in spring HERE. and in September HERE.
