When to prune astroloba spiralis 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 astroloba spiralis
Remove only fully dried, papery leaves by snipping them flush with the stem. Trim flower stalks at the base once flowers are spent.
Astroloba spiralis is a collector's succulent prized for its precise spiral leaf arrangement. It needs no pruning beyond removing dead lower leaves and spent flower stalks. Cutting into the growing tip or live stem will disfigure the plant permanently. Leave the natural column form completely intact.

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.
