Answer: The best way to keep birds from raiding your fruit tree is to drape birdnetting over the entire canopy and secure it to the trunk (to keep birds from entering from below the canopy and getting caught inside). Drape your tree before the fruit begins to ripen to keep the birds away. The oozing and black discoloration sound like a disease called fungal gummosis. It's difficult to control without a spray program beginning in late winter and continuing every 7-10 days until April. Your local cooperative extension has a publication about gummosis that will walk you through the treatment process. Maricopa County Cooperative Extension, 4341 E.

Good luck with your peach tree!
