Driving through the neighborhoods in Edmonton, I've noticed many trees that have been flagged by the city for replacement. The last few years of drought have taken their toll on the elms, birch and chokecherries planted on boulevards and in parks and parking lots. Many spruce show signs of water deprivation with reddish brown needles. Evans cherries had a tough go of it this winter. Many didn't make it through or suffered severe dieback. The prevention - water! So many times we had customers come to the greenhouse with samples and stories of drought ridden trees only to be told that watering would have made all the difference. Rain is not sufficient most of the time. We need to supplement, particularly during hot spells and in the fall to settle them in for winter. Folks, water your gardens (trees, shrubs, perennials) in the fall until the time the ground freezes. You want to create an ice block, upon freezing, that will slowly melt in the spring thaw and aid your tree with moisture that is badly needed. This also helps prevent the freeze/thaw effect that our spring brings.
