So my parents are getting our landscaping in, and they let me get some citrus trees. We all told our landscaper "semi-dward," but the ones that arrived say, for example "dwarf navel orange tree." I'm not sure if thats what they call semi-dwarf or what... should I complain and get him to get us semi-dwarfs instead? How big do each get? I don't want a tree so small that I barely get any fruit from. But my mom doesn't want it too big. Also I hear dwarfs are harder to take care of somehow?
