Q.windmill palm in a large pot outside
Our windmill palm is in a large pot outside. We want to plant it in the ground. We live in North Vancouver, B.C. and the palm would be in a west-facing location. It’s been in the large pot for five years and doesn’t seem to be growing much at all. It also has three stiff brown stems. I’ve trimmed the leaves which looked burnt.
Your growing zone is 7b, the Windmill Palm is hardy in zones 8a thru 11.
By the growing zones you are to cold, and remember these are guidelines. Weather trends and other conditions need to be considered.
I think I would repot and refresh the soil. This Palm generally is a slow growing variety.
Here is a link to refresh you on the growing conditions and care needed.
