Q: I bought a Japanese maple and I’d like to put it in a planter since I might sell my home in a few years. How big should it be?
A: I think a planter comparable to the size of a half whiskey barrel would be okay for a small Japanese maple. I’m assuming you bought a dwarf type, not one of the tall varieties. In this part of the country there is no need to protect the maple in the container during winter. If you decide not to take it on your next move, you could always transplant it out of the container into the landscape for the new homeowner.
