Changsha mandarin pollination
My "Changsha" mandarin has been completely hardy outdoors here in SE VA for 6 years, and last spring was completely covered in blooms. However, not one fruit was produced. Since there were no freezes, frosts or other adverse weather events after the flowers opened, I can only assume they weren't pollinated, although I did see bees and other insects visiting the tree. Does this variety require another cultivar for successful pollination and fruit production, and if so, what would be a possible match? Poncirus trifoliata is also hardy here, if that would work, but almost no other citrus will survive even the mildest of our winters.
