About Fruit development: petal fall to fruit coloring (April–May)

What should you be doing during this time?

Look for these pests and treat, if needed, according to the Cherry Pest Management Guidelines:

  • Black cherry aphids
  • Caterpillars
  • Earwigs
  • Peachtree borer
  • Western flower thrips
  • Armillaria root rot
  • Bacterial canker
  • Powdery mildew
  • Brown rot and Botrytis infections on fruit
  • Gophers
  • Phytophthora root and crown rot

Monitor mites by watching "hot spots" and examining water sprouts for developing infestations.

Survey weeds in late spring or early summer after summer annuals have germinated.

  • Record observations (PDF).
  • Control with cultivation or postemergence herbicides.
  • Keep areas around the base of trees free of vegetation to reduce problems from peachtree borer.
