It is almost March first on Vancouver Island. It went down to seven below last night but this is very unusual and we are generally very mild in the 7 above during the day and 2 to 4 above at night . I have three apple trees and three pear trees that need pruning plus a peach tree. There are also a number of Thuja type shrubs from 4 to 7 feet tall that need shaping and three need to have up to two feet cut off the top. Any suggestions? Is it the right time of the year for pruning. Will the trees take a rather heavy pruning so close to bud sprouting time?
