How to Grow Plum
Fruit Tree
Plums bring early spring blossom and juicy fruit for eating, bottling, jam and baking. A well-sited tree can be generous in a UK garden, but flowers are vulnerable to frost and branches may need support in heavy years. Compact rootstocks make bush, fan and patio-scale trees possible.
Planting & rootstocks
St Julien A is a useful semi-vigorous rootstock for ordinary gardens; Pixy is more dwarfing for small spaces and containers. Rootstock controls size and cropping speed. Plant bare-root trees from November to March in unfrozen, workable soil, with the graft union at least 10 cm above ground. Stake young bushes securely and water in well. A fan-trained plum can use a sheltered sunny wall, leaving enough room for mature branches.
Pollination
Many plums require a compatible partner with an overlapping pollination group, so check the named variety before purchase. 'Victoria' is self-fertile and a useful pollinator, although it often crops better with company. Local flowering times can differ, especially in colder districts. Ask the RHS or a local garden centre to confirm suitable partners, and avoid assuming any nearby plum will flower at the right time.
Care & pruning
Prune plums only in dry summer weather, after harvest or from late spring into summer, to reduce the risk of silver leaf and bacterial canker. Remove dead, damaged and congested shoots, but avoid severe cuts. Mulch in spring with well-rotted organic matter, keeping it clear of the trunk, and water young trees during drought. Thin crowded fruits where branches are overloaded, then prop heavily laden limbs carefully.
Years to bear
Pixy trees may crop after two to three years; St Julien A trees commonly take three to five years. Good pollination, frost protection and steady watering affect how soon reliable crops begin.
Harvest
Most UK plums ripen from July to September. Pick when fruits are fully coloured, fragrant and slightly soft near the stalk; they should come away with a gentle lift. Harvest in several passes because ripening is uneven. Eat dessert plums promptly, or refrigerate sound fruit briefly. Handle ripe plums gently to preserve their natural waxy bloom.
Common problems
Brown rot, plum moth, aphids, silver leaf and bacterial canker are important concerns. Remove mummified fruit promptly, collect fallen fruit, prune only in dry summer conditions and disinfect pruning tools between suspect trees. Encourage predators of aphids, use physical tree barriers where useful, and net crops against birds. Prevent stress through watering and mulching, particularly for young trees.
