When to prune 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 ox tongue
Grasp dried outer leaves at the base and peel them away from the stem. Avoid cutting healthy green leaves, which would leave unsightly stumps and damage the plant's appearance.
Ox Tongue (Gasteria bicolor var. liliputana) is a slow-growing, strap-leaved succulent that needs no pruning. Its distichous (two-ranked) leaf arrangement is natural. Remove only completely dried or damaged leaves by peeling them cleanly from the base. No shaping cuts are needed.

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.
