When to prune ficus retusa bonsai 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 ficus retusa bonsai
Pinch or cut back new shoots to 1–2 leaves once they extend to 4–6 leaves. For structural work, shorten branches back to a side branch growing in the desired direction. Seal large cuts with cut paste to prevent die-back.
Ficus retusa bonsai needs regular pruning to maintain its miniature form and build fine branch ramification. Pinch or cut back new shoots once they have extended 4–6 leaves, leaving 1–2 leaves. Regular trimming throughout the growing season keeps the canopy dense. Remove any crossing, downward, or dead branches at any time.

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.
