When to prune calathea ornata 'sanderiana' 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 ornata 'sanderiana'
Cut the petiole cleanly near the base with sharp, clean scissors. For leaves showing only brown tip damage, trim the affected edges following the natural leaf curve to restore appearance.
Calathea Ornata 'Sanderiana' needs no pruning beyond removing dead or damaged leaves. As a rhizomatous Goeppertia, it grows upward from a base and does not branch. Regular structural pruning is neither necessary nor beneficial. Simply cut away any yellowing or crispy leaves at the petiole base to keep the plant healthy.

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.
