When to prune corn plant 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 corn plant
Use a clean, sharp saw or loppers to cut the cane horizontally at the desired height. Dust the cut end with powdered cinnamon or activated charcoal to reduce rot risk. New shoots will emerge below the cut within 4–8 weeks. The severed top can be propagated as a cutting.
Corn Plant can be pruned to control height and encourage a multi-cane appearance. Cut the main cane straight across at whatever height you want — new growth will sprout just below the cut, creating a fuller top. This is the standard technique used commercially to produce the multi-stem Dracaena sold in garden centres. Best done in spring or early summer.

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.
