In this Guideline:


Outlined below in the shaded areas are approximate times of key cultural/monitoring practices for avocado trees growing in Santa Barbara and Ventura counties. Optimal times vary according to location, weather, and crop development stage. Testing foliage and soil generally are done once during the indicated period.
