Title: Non-native. Why are my potted Royal Empress trees dying?
Answered by: Joe Marcus
QUESTION:
I have purchased several Royal Empress trees over the past two years. Why won't they grow? Some sprouted leaves and then died while in the pots I planted them in. While others, that are 2 years old won't grow more than a foot the whole year. Help?!*ANSWER:
We know this is going to seem like a strange answer, but count yourself blessed. Royal Empress tree, Paulownia tomentosa has far more bad habits than it has endearing attributes. Above all, we think you should remove your Royal Empress trees and plant something less likely to cause you problems in the future. Several previous questions and answers to Ask Mr. Smarty Plants deal with the consequences of growing this invasive species:
Invasive, non-native Paulownia
Information about Invasive Paulownia Tree
Dead-appearing Royal Paulownia trees in Manteno, IL
Fast growing, possibly invasive trees for South Carolina
If, after reading of the horrors of owning one of these trees you still want one, you might contact your county's Cooperative Extension Service agent for advice. Growing trees in pots is tricky, especially in Colorado where the roots are very prone to freezing. Perhaps that is the issue with your trees.
