We had a contractor plant a 75 ft line as a barrier near our property line. He suggested Arborvitae Thuja 'Green Giant'. We relied on his recommendation and expertise. He planted 25 four foot Arborvitae trees on a 75 foot line, so the trees are around three feet (or less) apart. He also put 5 trees around our generator. They are less than 4 feet from the unit, and about 6 feet from the side of our house.
The trees went into the ground in Michigan, mid October 2018.
I think the trees are too close together, and too close to the generator. I may have to pull some out and plant them elsewhere.
Also, I am very concerned because the contractor also cut the central leader off all the trees. The tree tops look like runts.
Everything I have read said cutting off the tops will hurt vertical growth.
Any thoughts would be appreciated.
