Winter damage on deciduous trees and shrubs (Horticulture/Urban IPM)
Description:

With our severe temperature fluctions in April, many deciduous trees and shrubs had their buds damaged and appear to be dead. Deciduous trees should be given time to struggle through and recover. Many have secondary buds that are formed for just such an event, and may yet leaf out. Use a thumbnail to shallowly scrape into the cambium of the branch - if it is green, the branch is alive and needs to be given time to recover. Another test is the suppleness of the branch. Traditionally we recommend folks give their trees until at least the 4th of July to recover from such a winter, and sometimes even longer if the branches still appear to be alive.
