A small to medium deciduous tree to 7m with ornamental value. Looks beautiful in early spring/late winter with white blossoms on leafless branches.
There are notable differences in appearance, fruiting wood and fruit size/colour of the Japanese and European plum.
Japanese have rough bark, thin long leaves, large attractive fruits with yellow to red flesh especially in blood plums. European have smooth bark, rounded leaves, small rounded fruit with yellow solid flesh. The Japanese plum is more commonly cultivated Melbourne.
Bare rooted in winter.
A few are self-fertile (i.e. cherry plum, santa rosa), but the majority of cultivars need a compatible pollinator.
Prune after harvest in dry, breezy weather to prevent fungal disease. Japanese plums require annual pruning to promote new fruit bearing wood. European plums require less prudent pruning as they fruit on long lived spurs.
Brown rot (water with drippers or at ground level), leaf curl, wood borer moth.
During flowering and fruit set and as fruit ripen.
Autumn and Spring. Not as heavy feeders as other stone fruit.
Plums are best straight off the tree when fully ripe, remove from tree with a gentle twist.
