When to prune 'cossack pineapple' ground cherry in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune 'cossack pineapple' ground cherry
Remove any dead, diseased, or crossing stems with clean shears. If the plant sprawls excessively, use a tomato cage for support rather than pruning back growth.
'Cossack Pineapple' ground cherry is a naturally compact, bushy plant that needs very little pruning. The plant self-manages its branching well and fruits prolifically without intervention. Remove dead or diseased stems if they appear. Staking may help sprawling plants, but routine pruning is not necessary and may reduce yield.

Is it illegal to prune 'cossack pineapple' ground cherry in spring or summer in the UK?

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.
