How to Manage Pests
Pests in Gardens and Landscapes
Dormant almond buds are relatively insensitive to frost damage. Sensitivity to frost injury increases
gradually as the buds come out of dormancy. From midbloom until the fruits are the size of a pea or larger,
the crop can be significantly damaged by temperatures only slightly below freezing. Spring frost can blacken
and kill budding leaves, flowers, and young fruits.
To reduce the likelihood of frost injury, conserve heat by keeping the vegetation under trees mowed short,
so that the soil surface is firm and moistened. If overhead sprinklers are available, use them to prevent
frost injury when low temperatures occur during bloom. Trees can be protected from frost injury by covering
them with floating row cover or using protective shelters if freezing conditions occur during bloom or
early fruit growth. These covers should be prevented from touching the tree. Some varieties may be more
prone to frost than are others.
