Plum (Large) Growing Guide

Prunus domestica

Crop Rotation Group

Miscellaneous ●

Soil

Moisture-retentive clay or loam.

Position

Sunny spot, with excellent air circulation.

Frost tolerant

Yes, but it is important to choose varieties known to grow well in your area to reduce risk of losing blooms to spring freezes in cold areas.

Feeding

Feed with a rich mulch spring, then keep plum trees mulched with wood chips or sawdust.

Spacing

Single Plants: 5.00m (16' 4") each way (minimum)
Rows: 5.00m (16' 4") with 5.00m (16' 4") row gap (minimum)

Sow and Plant

Plant in winter while they are dormant. This gives them a chance to settle and develop their roots before putting their energy into spring growth. Dig a large hole - a wide hole is better than a very deep one - and mulch after planting. You may need to use a tree guard to protect the young tree from animal and insect pests. Young plum trees are at high risk for damage from insects that bore into the main trunk.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.

Notes

Some varieties are self-fertile; otherwise at least one other plum flowering at the same time will be required for pollination. Prune in late winter, before buds begin to swell.

Harvesting

Harvest when the fruit feels soft when gently squeezed. As fruit ripens, some fruits will fall from the tree, and others can easily be shaken onto cloths spread on the ground.
