When to prune florist's gloxinia 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 florist's gloxinia
Remove spent individual blooms at their stalks as they fade. Once the entire plant has finished flowering and leaves begin to yellow, cut all top growth back to about 2–3 cm above soil level, allow to dry, and store the tuber in a cool, dark spot.
Florist's Gloxinia needs light deadheading during bloom, but its main pruning moment comes after flowering ends. Cut all stems back to a few centimetres above the tuber to trigger dormancy, then store the tuber dry and cool. Regrowth in spring is vigorous. Do not prune during active blooming — it interrupts flowering.

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.
