Late snow and frost can impact your trees and shrubs in a variety of ways. Late snow (in March, April, or May) tends to be heavier, which can break branches and cause structural damage to trees and shrubs. If trees have already begun to grow spring buds, frost and snow can harm them. This can delay the growth of leaves and flowers, and even kill them entirely. Some trees and shrubs may suffer from frost damage. Trees and shrubs, especially those that already have leaves, can be toppled by the weight of spring snow or ice, particularly if the ground is very saturated. Winter weather in the spring can delay a variety of Plant Health Care (PHC) treatments. See more below. LEARN MORE > How to help your trees recover from snow damage
