When to prune dawn redwood 'ogon' in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune dawn redwood 'ogon'
Use clean loppers or a pruning saw on any dead or crossing branches, cutting at the branch collar. Never top the tree or remove the central leader.
Dawn Redwood 'Ogon' (synonym for 'Gold Rush' in some nurseries, also sold as a golden form) shares the same minimal pruning needs as the species. The tree's conical habit is self-forming. Remove only dead, damaged, or crossing wood in late winter. Preserve the central leader at all times.

Is it illegal to prune dawn redwood 'ogon' in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is.

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.
