Winerizing Japanese Maple in very large iron urn
I bought a Japanese maple last summer. It lived in the pot it came in through last winter and the spring of this year. This summer, I planted it into a huge Victorian iron urn. Now winter is here and I'd like to do whatever I can to make the maple "comfortable". The urn is too heavy to move indoors. I was thinking I could/should insulate the container to protect the roots, but not sure what with. Not sure what else I should do to protect the greenery. It will most certainly be exposed to snow. Any advice is welcomed. Thanks.
