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.
