When to prune candle plant 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 candle plant
Cut dead stems at the base with clean scissors once they are fully dry and shrivelled. Do not remove stems that still feel firm — they may resprout. Allow any cuts to callous before watering resumes.
Candle Plant goes summer-dormant and loses most of its leaves — this is normal, not a reason to prune. Remove any fully dead stems in early autumn as growth resumes. Trim straggling stems in spring if needed. Pruning needs are minimal.

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.
