A Warm Winter cuts both ways. While this past winter was good on our energy bills, it was a bit confusing to dormant trees and shrubs. Washington D.C. saw the earliest bloom ever of its famous cherry blossom trees. It was 10 days ahead of the earliest peak bloom in recorded history: March 15, 1990.
Now that the warm mild winter is behind us, excitement is in the air for the arriving spring season. Mild winters often trick Cherry trees, bulbs and other plants to bloom early only to be quickly knocked down by March snows and/or ice storms. This can cause damage to many prized evergreens.
The good news is that the brief late freeze we experienced at the opening of spring this year is not likely to kill or cause long-term damage to most of your shrubs and trees, unless they are a variety already prone to freeze damage.
