Care for Kwanzan Cherry: Borer Control:
Peach tree borers are a problem for these (and other) cherry trees. In fact, their susceptibility to a number of pests earns them dreaded "short-lived trees" label. For borer control, most experts simply advise keeping the tree vigorous (and therefore less susceptible to borer attack) by providing adequate irrigation and fertilizer. To fertilize organically, backfill with some compost when planting and top-dress periodically thereafter, watering the nutrients into the soil.
But I found a couple of experts who offer suggestions for more rigorous borer control.
The North Carolina State Extension advises that the "best time to apply a preventative spray to the base of peach trees is August 15 and again September 1." But once the caterpillars get under the bark, they warn, all hope is lost.
The University of California's integrated pest management experts offer tips that go beyond prevention. Spring is the time to implement the following borer control method:
"Treat affected trees with insecticide by spraying the trunk from the scaffold to the soil line. Apply the insecticide with a hand-held sprayer to the tree trunk from the juncture of the main scaffold limbs to the soil line. Cover the trunk thoroughly, using enough spray material so it will run off to form a small puddle at the base of the tree. Use from 0.5 to 1.5 gallons per tree, depending upon the size of the trunk."
