Need help pruning brugs
I inherited some brugmansias from my aunt when she died last year. Two are Ecuador Pink and one is Charles Grimaldi. The Ecuador Pink is blooming, but I accidentally put bloom fertilizer on it (didn't know better) and most of the leaves fell off. I'd really like it to be bushier. It's about 5 feet tall, and almost all trunk, which I hear is good, because I hear that means it can be a tree, but I don't want a tree, I want a bush.
When is the best time to prune it and root cuttings, and how much can I cut it back? Someone told me if I cut it back to the ground in the winter, it will come up from the roots and be a tree.
The Charles Grimaldi is still in a small pot, and I need to repot it. What is the best mix for it? Is a 5-gallon pot large enough?
