When to prune lupinus 'tequila flame' 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 lupinus 'tequila flame'
Remove spent spikes to a healthy side shoot to stimulate rebloom. After flowering is completely finished, cut stems back to the basal rosette. Clear away dead foliage in late autumn to reduce disease risk.
Lupinus 'Tequila Flame' benefits from prompt deadheading of spent flower spikes to encourage a second flush and prolong the display. Cut spikes back to a lateral shoot with visible buds. Cut the whole plant back to its basal rosette after the season and remove to ground level in autumn.

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.
