I have a healthy thriving mimosa with leaves that has not bloomed flowers yet. I gave it a shot of 20/20/20 about a month ago on someones advice. Nothing's happened. It's a lovely tree to look at, just wish it would show the pretty flowers it's known for. Any ideas?
Not old enough perhaps? They are very fast growing trees and will concentrate on just that for a few years. Also, 20-20-20 fertilizer will do more to promote growth (especially in a young tree) than flowering.
