When to prune calathea bacillaris 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 calathea bacillaris
Use clean, sharp scissors to remove the entire leaf and petiole at soil level. Avoid leaving stubs, which can rot.
Goeppertia bacillaris is a compact, clumping Calathea that rarely needs pruning. Simply remove leaves that have yellowed, dried out, or been damaged, cutting the petiole off at the base. The plant naturally maintains a tidy habit and does not produce sprawling stems or branches that need cutting back.

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.
