How to prune stone pine

Spring, during active shoot elongation (candle stage) for shaping; late winter for dead-wood removal. Pinch new spring candles by half to reduce extension and encourage back-budding. Remove dead or crossing branches back to a healthy lateral in late winter. Never cut back to bare wood without green needles — pines cannot bud from bare stems.

Rarely; candle pinching if desired annually in spring, dead-wood removal as needed. Stone pine (Pinus pinea) has a striking natural umbrella form that needs very little pruning — the shape is the ornamental value. In youth it requires clearing of dead lower branches as they self-shed. If size control or denser growth is wanted, pinch new spring candles back by half before needles fully elongate. Never cut back into old, bare wood on pines — they will not regenerate.
