There are also practical reasons to book early. Tree surgeons across Sussex and Surrey are in high demand through the summer months. Diaries fill from June onwards. Booking in May gives you more choice of dates and more flexibility on timing. It also means the work is done before the warmest months. Large-scale surgery on a tree in full leaf is harder, messier, and more disruptive to the garden.
A tree in full winter dormancy gives away very little. Dead wood and live wood can look almost identical when a tree has dropped its leaves. Canopy shape is harder to read. Structural weaknesses that show clearly under full foliage are invisible when the branches are bare.
May changes that. By the time spring growth is underway, the difference between live and dead wood is obvious. Dead wood sits bare while the rest of the canopy leafs out around it. Sections that failed to bud become easy to spot. Crown areas that are thinner than they should be stand out clearly. Branches carrying disproportionate weight as new growth adds load are visible in a way they simply were not in February.
This matters practically because a May survey gives a much more accurate picture of the work needed. Crown reduction carried out on accurate information is better targeted. It is also less likely to miss something. The same applies to pruning. Cutting in spring lets you see which branches are contributing to healthy growth and which are not.
Timing matters for the tree as well as the homeowner. Trees have annual growth cycles. Work carried out when a tree is actively growing gives it the best chance to recover. Wounds can compartmentalise and close before growth slows again in autumn.
When a branch is cut in spring, the tree is already producing callus tissue. This is the natural process by which it seals cut ends and protects against decay. That process happens faster in May and June than in autumn or early winter. As the tree moves into dormancy, repair slows down considerably.
For crown reductions and heavy pruning, spring timing makes a real difference. Any surgery involving significant cuts to main branches benefits from being done now. Those wounds close during the most productive growing period of the year. The tree goes into summer in better shape. It then has the whole growing season to stabilise before the stresses of autumn and winter arrive.
Sussex and Surrey see their share of summer storms. Mature trees with structural problems are the ones that suffer most when the weather turns. Crown weight builds significantly through May and June as foliage fills out. A branch that was borderline in April is under considerably more stress by July. Heavy rain combined with wind can expose weaknesses that were not obvious in dry conditions.
Getting a structural assessment done in May means the tree goes into summer already stabilised. Any necessary work can be completed before the heaviest-loaded period of the year begins. Crown thinning in May reduces wind resistance before summer growth peaks. Removing deadwood takes the unpredictable element out of the canopy. It means nothing comes down on its own terms during a summer storm.
For homeowners with trees close to buildings, fences, or parked vehicles, this is not a theoretical concern. A large branch coming down in July costs considerably more than planned surgery in May. The disruption is also harder to manage in the middle of summer.
This is a practical point worth understanding before you book. Under the Wildlife and Countryside Act 1981, it is an offence to damage or destroy an active bird’s nest. The main nesting season runs from roughly March through to August. The peak period for most species is April and May.
This does not mean tree work stops entirely during this period. It does mean that any significant pruning or felling requires a nest check first. A qualified tree surgeon will carry out that check before starting work. If an active nest is found, work on that section of the canopy must wait. It cannot proceed until the nest is no longer in use.
Some jobs booked for June or July run into delays for this reason. Nesting checks identify active nests that were not present when the job was originally scoped. Booking in early May and getting the work done promptly reduces that risk. By mid-May, the majority of early nesting is complete. A qualified arborist can carry out a check and advise on timing before any work begins.
At Tree Marshalls, nesting checks are standard on every survey. If there is any question about nesting activity, we tell you upfront. We will advise what can be done now and what needs to wait.
The volume of tree surgery enquiries across West Sussex, East Sussex, and Surrey picks up sharply from late May. It stays high through to September. Schools and local authorities typically run contracted maintenance work through the summer term. Commercial clients with grounds maintenance agreements schedule their annual work from June. Add residential demand and diaries fill faster than most people expect.
Calling in May rather than July or August gives you genuine flexibility on dates. You can pick a day that works around the rest of the garden and your own schedule. You can also plan around any other project you have lined up later in the year. Leaving it until high summer often means waiting several weeks for a slot. If the tree poses any kind of safety concern, that wait is uncomfortable.
Crown reduction and crown thinning are both well suited to May. The canopy is fully leafed, so the tree surgeon can see the full shape of the crown and make accurate cuts. Weight reduction before summer storms is a clear benefit. For trees that have been growing unchecked for several years, May is a good time to bring them back into shape. This is especially true where they are starting to crowd structures or shade out gardens more than wanted.
Deadwood removal is straightforward in May. Dead material is clearly visible against the background of active growth. This is one of the higher-value jobs to carry out at this time of year. It directly reduces the risk of unplanned branch failure through summer.
Crown lifting is also well timed in May. This involves removing lower branches to raise canopy clearance above a path, driveway, or structure. The full weight of the canopy is visible, cuts are clean, and recovery is fast.
For trees that need to come down entirely, May is no better or worse than any other time of year. The main practical consideration is ground conditions. Late spring ground in Sussex and Surrey is generally firmer than after heavy summer rainfall. Access for equipment is also easier before the garden is in full use.
Stump grinding is worth scheduling at the same time as any removal. A ground-level stump sitting in the middle of a lawn through the main garden season is more of a nuisance than one dealt with straight away.
For schools, managing agents, housing associations, and commercial sites, May sits in a useful gap in the calendar. Schools are in term time but not yet in the summer holidays. Access to grounds is easier to schedule around at this point. Summer holiday site closures are still a few weeks away. Work that needs to be completed before the summer break can be scoped, agreed, and done in May. There is no end-of-term pressure to contend with.
For managing agents with multiple sites, May is a practical time to get survey visits done. Reports and recommendations are then in hand before the summer begins. Any work that needs to go through a resident consultation or approval process has time to complete. It will not be rushed by the higher-demand months that follow.
If you are not sure what your trees need, the right starting point is a site visit and survey rather than a booking for specific work. Tree surgeons assess the full picture on site, identify any TPO or conservation area considerations, check for nesting activity, and give you an accurate picture of what the trees actually need, rather than what you might have assumed.
That survey in May sets you up for the rest of the year with a clear plan, whether the work happens now, later in the summer, or in the autumn.
Tree Marshalls carry out tree surgery and arboricultural services for domestic and commercial clients across Sussex and Surrey. May is one of our busiest booking periods, and slots fill ahead of the summer.
