Check trees for pests

Inspect trees weekly (especially new growth) for signs of pests. Wash foliage periodically with a forceful spray of water to dislodge aphids, spider mites and whiteflies. If an insecticide is needed, use a chemical with short residual activity, such as insecticidal soap, horticultural oil, pyrethrin, or Bt (for caterpillars)to protect beneficial insects
