Why Hasn’t My Brugmansia Bloomed In 3 Years?

Question

First pic is now. The 2nd is from May 2020 after drastic pruning. It Hasn’t bloomed in 3 years. I gave it some blooming fertilizer (high K) this summer. There are no “Y”s in the branching and it never has had any, so I don’t think that is the problem since it has bloomed before. Will bring inside soon due to cooling, frosty weather. I’m in Missouri. Can you help me know what is needed for getting it to bloom? Probably too late this year, but what about next? Thanks!

Answer 1

These plants are heavy feeders, and they will quickly outgrow a container. If you do not wish to keep moving up to a bigger container, then the best method will be root pruning this shrub. Here are some articles that will help:
