Yes

Flying Dragon is a dwarfing root stock that should do well in containers. However, being in a container will help dwarf the tree as well. I have satsuma's in containers that are not on flying dragon but are doing well, not too vigorous. Flying Dragon also has good cold tolerance.

Thanks so much. My tree is a Record Buck Farms tree from Lowes and it doesn't specify the root stock used. I guess I need to call the grower or check their website to see if they indicate root stocks used. An Owari Satsuma is on my wish list.

Fruit trees on dwarf rootstock begin producing fruit sooner (sometimes within the first 2 or 3 years), but the tree also will not have as long of a lifespan (maybe 10-15 years).

Another strategy, besides buying dwarf fruit trees, is to buy semi-dwarf and then just graft several different varieties into the same tree. Besides dwarf rootstock, continuous pruning can be used to keep trees small.

If it's staying in a container the rootstock won't matter much. The tree will be naturally dwarfed and the stress of container life will make it early fruiting.
