Avocado flesh can turn black from exposure to cold. When severe, fruit can develop brown, water-soaked spots in the skin, gray areas in the flesh, and may even crack or split.
- Foliage can turn brown and wilt, and scattered limbs or entire trees may die from cold temperatures.
- Frost and freezing occur under somewhat different conditions.
- Several frost control methods are available.
Test frost control systems by November and apply frost protections when warranted from about November through March, especially if growing on flat land.
