Hydrangea tree , bush cherries in containers?
I live in Chicago and would like to grow a hydrangea tree and some bush cherries in containers (not together). My yard is small and I dont have room to put another tree in the ground (I have one dwarf peach), but I would dearly love to have a hydrangea tree. Can they be grown in containers and be happy? Would I have to make special protections for the winter? Extra fertilizer? Is there a ratio of container size to plant that I need to be aware of? Any suggestions or advice would be appreciated. I dont want to do this and have the tree or the cherries hate where they live! Thanks.
