Look for vertebrates, especially during spring and summer. Manage if needed.
Reduce pest problems and manage tree growth by proper pruning.
- Test foliar nutrients and fertilize if needed.
Provide proper cultural care and good growing conditions to improve fruit yield and control pests. Pay particular attention to young trees and new groves.
Apply frost protection when warranted through March, especially if growing on flat land.
- Test frost control system by November.
Inspect trees or sample foliage or soil during late summer or fall before winter rains to assess salinity from alkaline soils, poor quality water, and fertilizers.
