UK pruning guide · RHS timing
When to prune chincherinchee in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune chincherinchee
Cut the spent flower spike cleanly at or just above soil level. Leave all green foliage intact until it yellows and collapses naturally. Remove or lift bulbs for storage once fully dormant.
Chincherinchee needs minimal pruning. Cut the spent flower stem at the base once blooms have fully faded to keep plants tidy and conserve bulb energy. The strap-like foliage must be left to die down naturally. In frost-prone areas the bulbs are often lifted — tidy foliage before storage.

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.
