Q. You recently identified that my peach trees had borers in them. I found the oval larval holes under the loose bark. Can I plant a new peach tree where I removed the afflicted tree? If so, are there any preventive measures I should take?
However, make sure you whitewash the next tree with either tree whitewash made from lime or dilute white latex paint, or nearly white latex paint, not an oil-based paint, with about the same amount of water and apply it to the trunk and main scaffold limbs.
Prune the tree so the canopy shades as much of the trunk and scaffold limbs as possible. Make sure the tree receives adequate water and if you can apply 3 to 4 inches of a woodchip surface mulch the tree will perform better and have less stress.

This borer can fly and comes in from other infested trees including many landscape trees and shrubs in the area. Sunburn or sunscald is the main culprit so providing shade on the trunk and lower limbs and giving it protection from whitewash helps reduce sunburn. Good luck.
