Seasonal climate variation affects chilling during dormancy, the accumulation of heat units during fruit development, threat from freeze damage, and impacts from diseases and pests.
In the Southeast, El Niño years tend to have more chilling and more rain during the dormant season than normal, while La Niña years have less chilling and may require additional irrigation during berry maturation. Damaging freezes are more common during Neutral years.
