Prunus domestica / P. salicina
Fast-fruiting deciduous stonefruit for temperate food forests. European and Japanese types cover a wide NZ climate range with the right cultivar and chill.
Also known as: Plum, European plum, Japanese plum

Ecological functions
Seasonal canopy · Early flower forage · Leaf litter
Wildlife value

Human uses
Fresh fruit · Preserves · Drying
Propagation
Grafted cultivars; check pollination requirements.
Maintenance
Annual pruning for light and airflow; thin fruit; manage silverleaf and pests.
NZ growing notes
One of the easier stonefruits for home food forests. Japanese types suit warmer districts; European types often handle cooler inland sites better.
In the food forest
Plum works as a low-tree fruit producer in mixed temperate guilds. Underplant with comfrey, yarrow and clover; leave space for harvest access and airflow.
Establishment
Plant in winter on free-draining ground. Establish pollinisers if required. Prune to an open framework. Mulch and keep grass back from the trunk.
NZ honesty
Broadly suited across temperate NZ, but spring frost can wipe blossom in hollows. Choose cultivars for your chill and disease pressure — local nursery advice beats catalogue hope.
