Cut Back Annuals

Most annuals and some perennials will bloom again if you keep the old blossoms cut off. Renew plants by trimming back old flowers plus some of the stem. Not only will you keep them tidy, but you'll help redirect the plant's energy from seed production into developing new flowering shoots and stems.

Control Apple Maggots

Apple maggot adults lay their eggs just beneath the skin of apples. The larvae tunnel into the ripening flesh and ruin the fruit. To control damage, lure the adults away from your fruit by hanging red rubber balls in your trees and covering them with a sticky substance, such as TangleFoot. When the adults land to lay eggs on the fake apple, they get stuck and die.

Prune Flowering Shrubs

Now is the time to prune back flowering shrubs such as spirea and lilac. Pruning later than mid-July will likely remove future flower buds. Remove errant branches and reduce the height of tall shrubs if needed. Open up the center of shrubs so the light can encourage the formation of more flowering branches.

Reseed Bare Spots

Summer is a good time to reseed bare spots in the lawn. Rough up the soil in bare areas with a rake, sprinkle grass seed, cover with peat moss or bark dust, and keep moist. In 7 to 10 days your new grass will sprout and grow, becoming lush and thick before autumn weather arrives.

Provide Morning Showers

This hottest part of the summer is perfect for fungus growth. Make sure you water in the morning, giving leaves and mulch time to dry off before nightfall. Nothing makes fungi happier than a warm, wet, still summer night.
