A variety of deciduous* fruit trees require a specific Agriculturalists and gardeners might consider delaying the planting of citrus number of cold hours to induce flowering, known as until methods have been developed for controlling the Asian Citrus Psyllid “minimum chilling requirement.” This is important to know (ACP). The insect carries one of the most devastating citrus diseases in the when selecting fruit trees for a climatic region. Since the world, Huanglongbing, also known as . ACP poses a inland valley region has mild winters, the trees listed and huge threat to backyard trees and commercial citrus. Research is currently demonstrated in the Ag Area have relatively low required being conducted to find methods to control the insect and citrus greening chilling hours, which are noted below. Chill hours are disease. measured by how many hours are recorded below 45°F. When we have very mild winters, even some of the trees California residents play a critical role in protecting California’s citrus.
