When to prune calathea crotalifera in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune calathea crotalifera
Cut spent flower stalks at the base once the bracts fade. Remove dead or yellowing leaves by cutting the stem cleanly at the plant's base.
Calathea crotalifera (rattlesnake plant) is a large tropical that needs little pruning indoors. Remove spent flower bracts and dead or damaged leaves as they appear. Outdoors in frost-free climates, cut back old flowering stalks after bloom. No hard pruning of healthy foliage is needed or recommended.

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.
