I made a mistake and bought a young sour Tamarind that has a main trunk that separates into two vertical branches going straight up. Basically, like a tuning fork or wishbone. problem is, I now realize as the tree grows, I'll get occluded bark and a weaker tree. So i want to trim one of the forks off, but not sure when the best time is to do so.
It's a young tree. The trunk caliper is about an inch+ thick. So, by doing this I'd be literally removing almost half the tree. Currently, it still has leaves, as I'm in a place where it hasn't quite gotten cold enough for the tree to go dormant.
