Frost protection
To conserve heat in the orchard and reduce the likelihood of frost injury, keep the vegetation around
trees low and closely mowed. This should be done well in advance of a possible frost so that the soil
surface can be firmed and moistened by the time the frost season begins.
If overhead sprinklers are available, use them on apples and pears to prevent frost injury when low
temperatures occur during bloom. Trees can be protected from frost injury and bacterial blast by covering
them or using protective shelters if freezing conditions occur during bloom or early fruit growth.
