When to prune calathea medallion 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 medallion
Snip brown leaf tips with sharp scissors at a slight angle matching the leaf's natural shape. Cut yellowed petioles at the base. Sterilise blades between plants to avoid spreading fungal issues.
Calathea Medallion needs minimal pruning. Remove brown-tipped or fully yellow leaves to keep the plant healthy and attractive. Browning tips are usually caused by low humidity or fluoride in tap water, so address the root cause rather than over-pruning. No structural cutting is required.

Pruning calathea medallion in the UK — FAQ
When should I prune calathea medallion in the UK?
Prune calathea medallion in spring, once growth resumes. 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.
Is it illegal to prune calathea medallion in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check calathea medallion for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
