i need some help with this pear tree
hi i recieved this pear tree in the mail a week ago. it is just a whip and about three feet high. it hasnt started to bud yet but it is alive.the question i have is there i knot of some sort about three inches from the top is kind of flimsy and it would break real easy if any pressure is applied.so can i just cut the tree off below the knot. that won't hurt the tree will it.i am in zone 5 or 6 depending which planting catalog you look at but i live at the bottom of michigan.
