When to prune gasteria (ox tongue) 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 gasteria (ox tongue)
Pull dried outer leaves gently downward from the stem. Cut spent flower stalks at the base once flowering is finished. To separate pups, unpot and gently twist or cut rooted offsets away from the mother plant.
Gasteria (Ox Tongue) needs very little pruning. It grows slowly in a stacked rosette and stays naturally tidy. Remove shrivelled or damaged outer leaves by pulling them cleanly away from the base. Flower stalks can be cut off after blooming if desired. Pups can be separated in spring as a propagation step.

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.
