When to prune waras' parodia 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 waras' parodia
Use a clean, sharp knife to excise soft or discoloured tissue only. Allow the wound to dry and callous fully before resuming normal watering. Do not cut healthy green tissue.
Waras' Parodia (Parodia warasii) is a globe-shaped cactus that requires virtually no pruning. Its single-stem form cannot be shaped by cutting. Simply remove any dead, soft, or damaged tissue at the base with a sterilised blade. Routine pruning serves no purpose for this species.

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.
