York Tree Surgery · Guide
Most people think of tree surgery as a summer job. It's the opposite. The best time for the heavy work — felling, crown reduction, pollarding and hard hedge reductions — is winter, when the tree is dormant. But some jobs suit summer, and the law restricts what you can do for half the year, so timing matters. Here's how the year breaks down in York.
This is when serious tree work happens. The tree is dormant so the sap is down, the bare canopy lets the climber read the structure and cut cleanly, and frost firms the ground so a chipper and timber can come off site without churning the lawn. There are no nesting-bird restrictions, so felling, crown reduction and pollarding are all at their best. It's also storm season — the gales come off the moors from October — so this is when emergency call-outs peak. Winter is also the right time to prune apple and pear.
Bird nesting season runs from roughly March to August, and it is a criminal offence under the Wildlife and Countryside Act 1981 to damage or destroy an active nest. That doesn't ban all tree work, but it means heavy cutting and felling is restricted, and a responsible tree surgeon will check for active nests before any work in this period. Trees with cavities or loose bark can also hold bat roosts, which are protected year-round and need a survey before work. So spring and early summer is mostly a time for surveys, planning and TPO applications rather than cutting.
A few jobs are actually better in summer. Cherries, plums and other Prunus species should be pruned in summer, not winter, to avoid silver leaf disease. Once birds have fledged — usually from late July — hedge cutting reopens for the late-summer trim. And summer is a good time to spot deadwood and disease while the tree is in full leaf, ready to deal with in autumn.
Dangerous and storm-damaged trees are dealt with at any time of year, nesting season or not. Work to remove an immediate risk to people or property is exempt from the usual restrictions, though the council should still be notified. If a tree is leaning, dropping limbs or has come down in a gale, don't wait for the 'right' season — get it looked at.
If your tree work isn't urgent, plan it for the dormant season and book early — every tree surgeon in York fills up from September. If your tree is protected by a TPO or sits in a conservation area, apply for consent in spring or summer (the council can take up to eight weeks) so the permission is ready when the season opens.
