I have a few mimosa's that are not blooming and lots that are...they all receive great sunshine too. Would you have some ideas as to why? Your info is greatly apprieciated ! I have loved these trees since I was a child and wish for blooms on all of them...thanks

Hi Gem and welcome to NGA,
I see you have had no answers to your question. Apparently nobody knows the answer, including me. A neighbor of mine has several mimosa trees and they are beautiful when in bloom. I do know that they won’t bloom until they are fully mature and about 10 feet tall. They also like very strong acidic soil. Are all your trees about the same age?
