Pruning Mulberry in Perth: Timing for Fruit Production

A Perth, Western Australia gardener pruned their young mulberry heavily last season and got no fruit. They ask when to prune for optimal fruiting.

Optimal Pruning Window

Late fall to early spring (dormant season). In Perth's Mediterranean climate, this means June-August (winter). Prune after leaf drop, before spring bud swell.

Why Last Year's Pruning Eliminated Fruit

Mulberries fruit on new growth from the previous season. Heavy dormant pruning removes the wood that would have borne fruit. Light annual pruning maintains fruiting wood.

Pruning Principles

• Remove dead/diseased/crossing branches
• Thin crowded centers for light penetration
• Shorten long leaders to maintain harvestable height
• Never remove >1/3 of canopy in one year
• Prune to an open, vase-like structure

Large Limb Technique

Three-cut method: undercut 12" out, top cut 1" further, final cut at branch collar. No wound dressing needed.

Annual Maintenance

Light pruning every year beats severe pruning occasionally. Gradually remove lower branches over 5+ years if clearance needed. Mulberries are resilient but respond best to consistent, moderate management.
