Re: Growing Windmill palms in zone 6?
Hmm here we had several long cold winters in a row. And most if not all Trachycarpus fortunei survived. Some looked pretty bad after the winter. But they recover fast. We had lots of snow and temperatures of -18 c° long cold wet periods. -10 c° doesn't do much damage. Perhaps you can find a local grower. Cause palms grown in a colder climate are much hardier and don't need to adjust. It's best you plant yours in spring so they can settle.
