There are two types of plums: the European plum, which is suited to cool climates and the Japanese plum, which grows better in warmer areas. They can grow up to 4m high and wide, but don’t fret if you don’t’ have the space – they’re available in dwarf forms, too.
When growing in pots or small spaces, choose a dwarf varieties, such as Ruby Blood, Satsuma or Mariposa Dwarf plums. Remember, you’ll need at least two fruit trees for fruit set, but if you don’t have room, grow Santa Rosa Dwarf plum, which is self-fertile.
Neither European nor Japanese plums (with the exception of ‘Santa Rosa’) are self fertile and require a pollinator belonging to the same group to set fruit. Japanese and European plums do not cross-pollinate as they are different species.
