As we just experienced, February can bring unexpected rain, cold temperatures, and storms to the Portland area. Due to the amount of snow and freezing rain our trees suffered. Many trees have broken limbs.
A combination of rain, cold temperatures and storms can contribute to flooding. Especially toward the end of the month when temperatures typically start rising while we start preparing for early spring.
Flooding can cause damage to our landscaping. It can alter the soil causing trees and shrubs to be less stable due to root damage. In severe cases, it can cause a tree or shrub to fall, especially if flooding is combined with wind. Tolerance of flood damage depends on the age of the tree, and if the tree is dormant or not. Flooding is more detrimental during growing season than dormancy.
