Is there a way to get my avocado tree to continue growing the main trunk?
I trimmed the trunk because it was growing quite tall and spindly. Is there any way to continue growing the main trunk or will it only grow branches now?
The main trunk will stay the same height at this point, but it will get thicker as it matures. Your best bet is to encourage a few branches out and go for a wine glass shape off the main trunk. With some pruning you can make it look like a pretty nice dwarf tree!
