When to prune tongue leaf plant in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune tongue leaf plant
Grasp dried, shrivelled outer leaves at the base and pull gently downward to detach cleanly. Use clean scissors only if a leaf does not pull free easily.
Tongue Leaf Plant (Glottiphyllum longum) is a compact South African succulent that needs almost no pruning. Simply remove dead or shrivelled leaves by pulling them cleanly from the base as they dry. Do not cut into healthy green leaves — the plant's natural form is low and spreading.

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.
