When to prune pecan 'cheyenne' 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 pecan 'cheyenne'
Young trees: select a dominant central leader and scaffold branches spaced 45–60 cm apart. Mature trees: remove water sprouts at their base, prune out dead, damaged, or crossing wood with clean cuts outside the branch collar. Avoid heavy pruning that delays bearing.
Pecan 'Cheyenne' is an earlier-bearing, smaller-framed cultivar, but pruning practice is the same as for other pecans. Train to a central leader when young. Mature trees need annual dormant pruning to remove dead wood, water sprouts, and crossed limbs. Keeping the canopy open improves nut size and reduces disease.

Is it illegal to prune pecan 'cheyenne' in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check pecan 'cheyenne' for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
