I would like to call on the wisdom and experience of this forum to help me choose best rootstock for Kishu Mandarin. I am looking for cold hardiness ( zone
, quality, and production. I have well draining sandy loam soil in west central Ga....on the fall line. I have protection measures in place for winter. I am fairly new at this, but have made several successful grafts, though I hear Kishu is very hard to get to take. I have Kinkoji, Trifoliata, Flying dragon, Swingle and US852 rootstock to choose from. Any suggestions?
