When to prune calathea network 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 network
Snip dead or damaged leaves at the base of each petiole with sterilised scissors. Avoid cutting into healthy leaf tissue, which can cause browning at the wound site.
Calathea Network requires no shaping or structural pruning. Its intricate mosaic-patterned leaves grow directly from the base as a clumping rosette. Remove any leaves that have yellowed, crisped at the edges, or died back by cutting cleanly at the base of the petiole.

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.
