Is there a tree that will grow in whiskey barrel containers?
Wayne County Michigan
There are a number of trees and shrubs that can be grown in containers. Pick something that is winter hardy in our area, that doesn't grow too tall and can be easily pruned.
You also will need to make drainage holes in your barrels so that the roots do not become waterlogged.
