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?

There is no problem planting in the same hole. This insect burrows into the
tree, not the soil.
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.

Make sure you keep surface mulches a safe
distance from the trunk so it does not cause it to rot from excess moisture.
That has a known history of good performance in our desert. You can go to my
blog, extremehorticulture of the desert, and search for recommended fruit tree
varieties if you don’t have one in mind.
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.
