When to prune cryptocoryne parva 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 cryptocoryne parva
Carefully snip individual yellowing leaves at the base with fine aquarium scissors. Daughter plants on runners can be separated once they have two to three leaves. Because of its tiny size, handle with care to avoid uprooting the shallow root system.
Cryptocoryne parva is the smallest Cryptocoryne species and needs almost no pruning. It grows very slowly, so simply remove any yellowing or dying leaves as they appear. Runners spread gradually and can be trimmed or separated. No scheduled pruning is needed — it is among the lowest-maintenance aquarium plants available.

Is it illegal to prune cryptocoryne parva 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.
