When to prune zz plant raven 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 zz plant raven
Cut unwanted stems cleanly at soil level using sterile scissors. Avoid removing healthy new growth, which starts green before turning black.
ZZ Plant Raven needs minimal pruning. The deep-purple-black leaflets emerge green and darken with maturity — do not remove them prematurely. Cut back any yellowed or damaged stems at the base. The plant rarely gets leggy indoors; if a stem is damaged, remove it at soil level and the rhizome will send up a new one.

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.
