When to prune amaryllis 'picotee' in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune amaryllis 'picotee'
Cut the spent stalk with clean scissors to about 2 inches above the bulb. Never cut healthy green leaves. If resting the bulb for dormancy in autumn, remove yellowed leaves at the base only once fully dead.
Amaryllis 'Picotee' needs only post-bloom stalk removal. Once its white red-edged flowers fade, cut the hollow flower stalk to about 2 inches above the bulb. Keep all green strap leaves through spring and summer to rebuild the bulb. Remove a leaf only when it turns fully yellow and dies back on its own.

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.
