As you all know this will go down as a summer to remember (or forget). Not only has the summer been unbearable lest we forget about the April cold blast that left our plant material in tatters. Our hope then was to have a normal summer so that trees and shrubs could recover their stores of carbohydrates before the onset of winter. That has likely not happened. Unfortunatley we will be dealing with the loss of old and young trees for several years to come as a result of the this most unlikely weather.
This fall you should prepare to fertilize all plant material once a killing frost has occurred. A soil sample will help deterimine what we need to apply however if that is not done 10 lbs of 10-10-10 per 1000ft2 twice this fall six weeks apart will help significantly. If you have the water resources it will only benefit if you can apply 1inch of water per week to any and all trees and shrubs.
