I am looking for a dwarf cherry that will do well in a whiskey barrel. I realize standard cherries can get to be over 40' tall, but the soil I have on my property is total garbage, so I am resorting to barrels. I have a dwarf peach that is in a whiskey barrel right now in it's second year that is doing great. I wrote to Raintree, and they recommended Lapins, Sweetheart, and Stella (all on Gisela 5 rootstock), but they didnt mention the height. I want something at 9' or below if possible. Any suggestions?
