When to prune anubias barteri var. nana 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 anubias barteri var. nana
Use sharp, clean aquarium scissors to cut individual leaves at their base. For division, cut the rhizome cleanly with a sterile blade, ensuring each piece retains at least two to three healthy leaves. Attach divisions to hardscape — never bury the rhizome.
Anubias nana is a slow-growing aquarium plant that rarely needs pruning beyond removing old or damaged leaves. Trim yellowed or algae-coated leaves cleanly at the petiole base. The rhizome should never be buried or cut unless dividing for propagation. This is a very low-maintenance plant.

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.
