When to prune thanksgiving cactus 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 thanksgiving cactus
Pinch or gently twist individual stem segments (phylloclades) off at the joints using your fingers or clean scissors — no cutting tool required. Remove one to two segments per stem tip to encourage branching. Clear out any dead or shriveled segments at any time.
Thanksgiving Cactus benefits from light pruning after flowering to encourage bushier growth and more blooms next season. Pinch or twist off one to two stem segments at the joints in late winter or spring. This promotes branching and a fuller plant. Remove any dead, limp, or damaged segments year-round as needed.

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.
