Landschoot suggests some general lawn practices for summer. Also, you don't need to mow as often because the grass isn't growing as fast. Mowing actually wounds the grass, because you're cutting leaf tissue from the plant, he explains. Mowing doesn't damage the plant permanently, but when grass is stressed by heat and drought, it can lose moisture from the cut tips and must spend energy on healing. If you walk around neighborhoods during a drought, you often can see brown or tan stripes where wheels rolled across the grass.
Activities also can hurt turf.
When you put a lot of traffic on stressed grass, you may have to repair your lawn in the fall. Weed control and fertilization Landschoot recommends homeowners not use weed control products during the summer. It's also not a good idea to fertilize your lawn in summer. The best time to fertilize in Pennsylvania is May, September and November. In the summer, he explains, fertilization can make your grass too lush, which makes it more vulnerable to heat and drought.
