Answer: It sounds like your tree may be suffering from peach leaf curl, a fungal disease which causes the symptoms you describe--newly emerging leaves become puckered and leathery-feeling, then turn brown. Mild infections can be kept in check with diligent pruning--remove affected areas immediately and destroy. Healthy trees will be able to withstand some infection, so be sure your tree gets plenty of water and nutrients. An annual mulching with well-rotted compost will help. If you see the infection spreading throughout the tree, contact your county Extension agent for your spray options for your region. Their number is 202/274-6900.
