When to prune ridley's hohenbergia 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 ridley's hohenbergia
Cut the spent parent rosette away at the base with clean, sharp shears. For pup removal, slice as close to the base of the offset as possible, dip the cut end in fungicide, and pot in a fast-draining bromeliad mix.
Ridley's Hohenbergia requires minimal pruning. The parent rosette dies after blooming and should be cut away once it has fully browned. Remove dead or damaged leaves at any time using sterilized tools. Hohenbergia can take up to five years to reach flowering maturity, so the main task is pup management rather than routine cutting.

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.
