How to Manage Pests

Pests in Gardens and Landscapes

Frost injury

Mild frost may produce shoot dieback and browning of the seed coat. Young fruit may drop.

Solutions

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 on stone fruits 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.
