small space for a tree
I have a 4' x 4' square of dirt on my concrete patio. I would like to plant a dwarf, semi dwarf or columnar tree in this spot. I am worried about root space and would like to get something that would be okay in a space that small. I assume that trees that can be grown in pots would work well? I would prefer a fruit tree of some sort. The space is full sun all day. We get a lot of rain throughout the year. Also I live at the top of a hill, so there is a lot of wind that comes through our yard. I have been looking at Stella Cherry trees.
