UK pruning guide · RHS timing
When to prune neli's tongue 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 neli's tongue plant
Peel away completely dried outer leaves with your fingers or tweezers. If a leaf base is soft or rotting, use clean scissors and dust the cut with cinnamon or sulphur powder to prevent infection.
Neli's Tongue Plant (Glottiphyllum nelii) requires virtually no pruning. Its paired succulent leaves form a naturally tidy rosette. Prune only to remove fully dead or rotting leaves by peeling them away from the base. Cutting healthy tissue is unnecessary and can introduce disease.

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.
