Would spacing them 18" now cause issues down the road with the roots? I'm looking for a hedge that is tight/without gaps. I don't mind waiting for them to grow together over time, if planted 36" apart....I just want to ensure that 36" would still form the hedge style I'm after.
Note: I've already planted 36" apart, but (of course) now I'm second guessing.
