Leaf galls are swellings caused by bacteria, fungi, viruses, and insects. They're common on azaleas, rhododendrons, and camellias. Handpick and burn the affected plant parts.
Leaf curl, also called leaf blister, is a yellow to red arched, curled, puckered, or distorted leaf that will drop early. The curls are common on peach and plum trees where fruits become swollen and bladder-like. Dormant oil spray and other recommended sprays are often effective. Remove and destroy affected leaves.
