About 10 years ago my neighbor planted two rows (staggered) of evergreens to act as a privacy barrier.
Now the trees are getting pretty big and he is concerned that they might choke each other out and die. He could remove one of the rows but the "insides" of the trees don't have any healthy growth since not much light gets in there.
Questions are:
- Is it possible that the trees could choke each other out or can they survive close to each other?
- If he does remove a row will the previously unexposed side of the tree generate new growth or will the just look nasty forever.
Thanks for the help.
