When to prune cordyline in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune cordyline
Pull or cut yellowed lower leaves cleanly from the stem. For hard renovation, cut the stem back to 30–60 cm above soil level in spring; new growth will emerge from dormant buds. Avoid cutting healthy green leaves unnecessarily.
Cordyline requires minimal pruning indoors. Remove lower leaves as they naturally yellow and die — this is normal, revealing the characteristic trunk over time. Outdoor or large specimens can be cut back hard if they become top-heavy or suffer cold damage; they regenerate vigorously from the base or cut stem.

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.
