Red Sunset maple lacks central leader?
We planted a Red Sunset maple about 3 years ago, balled and burlapped so it was already a decent size.
Last year I noticed it seems to lack a central leader. It's more vase-shaped with about 3 or 4 branches splitting off from the main trunk. This seems to be the natural growth habit of this particular tree. The one that looks the strongest of the lot is actually not in the center but off a bit to one side and growing at a slight angle.
I can get pics but didn't have time tonight.
So the question is, is this a normal growth habit for this particular maple? Was it poor pruning by the nursery? Or just to be expected? And should I be concerned at this point? The tree is getting quite tall. I just pruned off some lower branches tonight, but any corrections to the main branches at this point would probably need to be done by someone else.
