My elderly neighbour has the most amazing functional garden, loads of fruit trees which she has now enlisted my help in managing as she can't physically do it any more. Picking plums has put me in the mood to try growing my own, but as a renter I would have to grow in pots. Are there dwarf varieties that would be suitable? I bought a fig tree this year that I intend to prune into a shrub next year, but would like to try plum and cherry. Is this possible?
