When to prune freesia 'royal blue' 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 freesia 'royal blue'
Cut spent flower spikes back to the nearest leaf or main stem junction. Allow all foliage to senesce naturally before cutting to ground level, ensuring the corm recovers energy for the next growing season.
Freesia 'Royal Blue' requires minimal pruning. Remove spent flower spikes by cutting back to the stem once all blooms have faded. Leave foliage in place to die back naturally after flowering — this is essential for corm health. Once leaves are fully yellow and dry, remove them at ground level.

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.
