Topping off 6 foot tree.
I have a Plumi tree that is over 6 foot and I'm having problems bringing it in through the sliding door for the winter. I need to start topping it off. Is there any special procedure that I must follow. I usually bring them in in early September here in Michigan. I thought taking out half of the top this fall when I bring it in during the fall, then the following year taking out what was remaining. OR... Should I trim now (Late July) or next spring when I set it out for the summer. Please help.
