Japanese Maple Pruning: Timing, Technique, and Tool Care

Best Time

Dormant season: Late November to early January (after leaf drop, before sap rise).

Pruning Principles

• Cut just beyond a pair of buds → encourages two side shoots.
• Large limbs: cut at branch collar (swollen base), never flush.
• No stubs—they rot and invite disease.
• No wound paint—research shows it hinders healing.

Tool Rules

• Sharp tools only—clean cuts heal faster.
• Sterilize between trees (alcohol, bleach solution) to prevent disease spread.

Seasonal Exceptions

Light corrective pruning (wayward shoots, dead wood) can be done anytime except during spring sap rise (when leaves are emerging).
