I have a dwarf lemon and an orange tree kept in pots that are 12 inches across. The trees are over 40 years old. I live in NY and have to bring them in each winter. I would like to know what type of fertilizer I would use on these small trees and how to apply it, as well as when. The orange tree has fruit that is the size of a large marble.the lemon tree has round fruit that is mellow to the taste. It also has a very thin rind. Do you have any idea what kind of trees these are? These were my mother's.

I suspect that the orange is a calamondin and the lemon may be a meyer. They would fit those descriptions.
