Your Practical Guide to Tree Health Checks
A mature tree can make a garden feel private, settled and valuable. It can also change quickly after a wet Belgian winter, a hot dry spell or stormy weather. This guide to tree health checks helps homeowners spot visible warning signs early, understand what can wait and recognise when a professional assessment is the sensible next step.
For busy households, the aim is not to become an arborist. It is to notice changes before a small pruning job, drainage issue or pest problem becomes a fallen branch, a bare lawn or damage to a fence, terrace or neighbouring property.
Start with a safe view from the ground
Begin several metres away from the tree. Look at its overall shape rather than focusing immediately on one leaf or branch. A healthy established tree usually has a balanced canopy for its species and growing conditions, with foliage spread reasonably evenly across the crown during its growing season.
Ask whether anything has changed since last year. Is one side thinner? Are there dead branches standing out against green growth? Has the tree started leaning, or does the soil appear raised and cracked on one side of the trunk? Sudden changes matter more than a naturally uneven shape.
Do not climb the tree, pull at branches or stand beneath a visibly damaged canopy. Branches that look secure from below can be weak internally, particularly after prolonged rain, wind or fungal decay. If a branch is hanging over a drive, entrance, play area, public pavement or a neighbour's garden, treat it as a priority rather than a weekend task.
Check the leaves, buds and new growth
Leaves offer useful clues, but they need context. A deciduous tree without leaves in January is doing exactly what it should. The same tree with sparse leaves in late spring may need closer attention.
Look for leaves that are unusually small, curled, spotted, yellowing outside the normal autumn period, or dropping much earlier than expected. Check whether the issue affects the whole canopy or only a few branches. Damage limited to one area can point to a broken limb, local disease or shade changes, while problems across the tree may relate to roots, drought stress, compacted soil or pests.
New shoots are another helpful indicator. Healthy trees generally make fresh growth in season, although the amount varies widely by species, age and recent pruning. Lots of shoots emerging from the base or along the main trunk can sometimes be a stress response. It does not automatically mean the tree is failing, but it is worth reporting when requesting a garden visit.
Avoid treating discoloured leaves with a product before you know the cause. Some leaf marks are cosmetic, some are weather-related and some are linked to disease. Unnecessary spraying can affect beneficial insects and does not solve root or structural problems.
Examine the trunk without causing damage
Walk around the trunk and inspect it at eye level and near the base. Healthy bark differs greatly between species, so the concern is not roughness alone. Look instead for new cracks, long splits, loose sections of bark, deep wounds, wet patches, hollow areas or unusual oozing.
Fungal brackets or mushroom-like growth at the base deserve attention. Fungi can appear on dead wood without creating an immediate emergency, but growth around roots or the lower trunk may indicate decay within the tree. Take a clear photograph from a safe distance and arrange an assessment, especially if the tree is large or close to a building.
Be cautious with old pruning wounds. A correctly cut branch collar can close over time, but large stubs, torn bark and cuts made too close to the trunk are more vulnerable to decay. Painting wounds is rarely the answer. Better pruning decisions, made at the right time for the species, are more useful than a cosmetic cover-up.
Check the root zone, not just the crown
Many tree problems begin below ground. The root zone often extends well beyond the visible canopy, and it is easily damaged by repeated foot traffic, parked cars, building work, deep digging or a newly laid patio.
Look for compacted bare soil, standing water, exposed roots, fresh soil heave or a sudden lean. A tree struggling after landscaping work may not show symptoms immediately. Reduced leaf size or dieback can appear months later, once damaged roots can no longer supply enough water and nutrients.
Mulch can help retain moisture and reduce competition from grass, but it should not be piled against the trunk. A thick mound touching the bark traps moisture and can encourage rot. Keep a clear gap around the trunk and use a shallow, even layer of suitable organic mulch where appropriate.
Watering also depends on the tree. Newly planted trees need regular attention through dry periods, while established specimens usually benefit more from a slow, deep soak during genuine drought than frequent light watering. If your garden has heavy clay soil, drainage and compaction can be as relevant as lack of water.
A guide to tree health checks after wind and heavy rain
After severe weather, start with the area around the tree. Fallen twigs are common and not usually alarming. Large branches, fresh splits, a changed lean, torn roots or cracks in the ground are different matters.
Do not attempt to remove a partly detached branch with a ladder or pole saw. The weight and movement of the branch can be unpredictable. Keep people, pets and vehicles away from the area, particularly when overhead cables, roofs or boundary fences are involved.
A recent Waterloo garden clean-up showed why this approach matters. Before the work, the owners could see only a few scattered branches after a windy week. From ground level, our team also found a heavy dead limb caught in the upper canopy of an old lime tree, directly above the garden path. The path was kept clear, the hazardous material was removed safely and the surrounding shrubs and lawn were tidied afterwards. The result was not simply a neater garden - it was a usable route to the house again, with a clear plan for seasonal monitoring of the tree.
This is the value of checking after weather rather than waiting until the next routine tidy-up. A garden can look mostly fine while one overlooked branch creates a real risk.
Know what you can maintain yourself
Light ground-level care can support tree health. Removing fallen diseased leaves where practical, keeping mulch away from the trunk, watering a young tree in dry weather and preventing lawn equipment from striking the bark are all worthwhile.
Pruning is more conditional. Small, clearly dead twigs that can be reached from the ground may be straightforward, but larger branches require knowledge of safe cuts, seasonal timing and the tree's response. Heavy reduction can create weak regrowth, poor shape and stress. It may also remove nesting habitat, so work should always be planned with wildlife and local requirements in mind.
The right choice depends on the species, size, position and condition of the tree. An ornamental cherry beside a terrace needs a different approach from a mature beech near a boundary. If you are unsure whether a branch is dead, diseased or simply dormant, wait for informed advice rather than cutting blindly.
Keep a simple record between visits
Photographs make tree health checks far more useful. Take a whole-tree photograph from the same position each season, plus closer images of any bark wound, fungus, leaf damage or soil change. Note when you first saw it and whether it has spread.
This record is particularly helpful for landlords, diplomatic properties and homeowners who travel regularly. It gives a gardening team a clearer starting point and helps distinguish a longstanding feature from a new concern. It also makes recurring garden maintenance more purposeful: the team can monitor changes while handling lawn care, hedge trimming, weeding and seasonal clean-ups.
When to arrange professional help
Contact a qualified professional promptly if you notice a new or increasing lean, cracked major limbs, dead branches over a used area, root movement, fungal growth at the base, storm damage, or a tree affecting buildings and access routes. The same applies when a tree's canopy is declining across more than one season.
A practical visit should begin with what you can see from the ground, the tree's position and the work needed to make the garden safe and presentable. Sometimes the answer is targeted pruning and removal of dead wood. In other cases, a specialist tree assessment may be required before any major work is planned. Clear photographs sent by WhatsApp can help us understand the situation and provide a fast quotation for suitable garden work.
A few minutes spent looking up, around and below a tree can protect the garden you enjoy every day. If something does not look right, trust that observation and arrange help before the next spell of wind turns a manageable job into an urgent one.
