Pruning Emerald Green Arborvitae leaders
I have 2 of everyone's favorite big box store tree...the Emerald Green Arborvitae...complete with 3 and 4 competing primary leaders.
They are around 5 feet high now, and I rather like them. I plan on simply making a ziptie ring around the current leader cluster for snow support in case they need some. For future growth however, I would only like to see 1 or 2 leaders going up. How could I accomplish this?
Should I just cut back the unwanted leaders? Will the trees then focus growth to the topmost leaders? How far down should I prune the leaders to effectly refocus growth? Does this sound like something that might actually work?
Thanks for any tips!
