When to prune anubias barteri var. nana 'petite' 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 'petite'
Snip damaged or algae-covered leaves cleanly at the petiole with fine aquarium scissors. If dividing, cut the rhizome with a sterile blade ensuring each piece has at least two leaves. Keep the rhizome tied to rock or wood — never buried in substrate.
Anubias nana 'Petite' is a miniature, very slow-growing aquarium plant that needs almost no pruning. Remove individual leaves only when they yellow, die, or become heavily coated in algae. The tiny rhizome should never be cut unless dividing for propagation. Its compact size makes overgrowth rarely an issue.

Pruning anubias barteri var. nana 'petite' in the UK — FAQ
When should I prune anubias barteri var. nana 'petite' in the UK?
Prune anubias barteri var. nana 'petite' in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

Is it illegal to prune anubias barteri var. nana 'petite' 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.
