When to prune spear head 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 spear head
Snip leggy stems just above a healthy leaf with clean scissors. Remove dead or yellowing leaves by pulling gently at the base or cutting cleanly. Allow cuttings to callous before propagating.
Spear Head succulent needs very little pruning. Remove dead leaves or spent flower stems as needed. If the plant becomes stretched or leggy due to low light, trim it back in spring and use the cuttings to propagate. No regular pruning schedule is required.

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.
