Creating an uneven lawn, which leads to uneven mowing and scalping.
How do you thin out grass?
If the entire lawn is thin and patchy, a general overseeding might be the best remedy. Begin by mowing the existing lawn as short as possible so new grass seedlings will get enough sunshine. To reduce thatch so seed can contact soil, power raking (dethatching), core aeration or brisk hand-raking will help.
Is a thick lawn good?
Shown: A thick, well-fed lawn is your best defense against weeds, which can’t compete for space and nutrients. Leaving the grass long, 3 inches or more, encourages roots to grow deeper, where they’ll weather drought better. Taller grass also casts shade, preventing weed seeds from germinating.
