In June–July, cut all spring candles to the base with scissors — this forces new buds to break in late summer into fine autumn growth. In autumn, thin autumn shoots to 2 per node, remove old needles leaving 6–8 pairs, and remove weak or crowded branches.
How often does japanese black pine need pruning?
Decandling annually in summer; autumn needle work and refinement annually.
