When to prune crassula marnieriana in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune crassula marnieriana
Pinch off stem tips or cut with clean scissors just above a leaf node to encourage branching. Remove spent flower stalks at their base. Wear gloves — sap can irritate skin.
Crassula marnieriana (Jade Necklace) benefits from light pruning to maintain a tidy form and encourage bushy growth. Stems can become straggly over time. Pinch or cut back leggy stems by one-third in spring, just above a leaf node. Remove spent flower clusters after blooming. Cuttings root readily.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
