Effects of Freezes on Avocado Trees
While healthy avocado trees can tolerate freezes between 30 F and 32 F, severe freezes are capable of destroying individual avocado trees — particularly freeze temperatures falling below 30 F. The colder and longer the freeze, the greater the potential for damage to your avocado grove.
Effect of Cold Temperatures on Fruit Set
In California avocado groves, cool temperatures before and during the main period of bloom can have an adverse effect on avocado production. Cold temperatures also affect tree pollination.
Freeze Protection of California Avocado Groves
Freeze damage can reduce spring flowering, so be aware of temperatures falling below 30-degrees Fahrenheit, regardless of weather forecasts. Rather than rely on forecasts, establish a frost management plan and follow it.
