Winter Tree Health Checklist
Winter arrives more gently in Brighton than in many other parts of the country, but the mix of coastal winds, damp air and sudden frosts can still put pressure on garden trees. Taking a little care now, before the colder weather settles in, can make a real difference to how well your trees cope over the winter months.
Preparing your trees early helps reduce the risk of storm damage, protects them from frost, and supports stronger growth when spring returns. This simple checklist is designed for Brighton homeowners who want healthy, safe and well-maintained gardens throughout the colder season.
Why Winter Tree Care Matters in Brighton’s Climate
Brighton’s weather is shaped by its coastal position. Winds can be strong even on mild days, and the build-up of dampness in late autumn can affect tree bark, roots and surrounding soil. Frost sometimes appears later here, but when it does hit, it tends to be sharp and sudden.
This combination makes winter tree health an important part of garden maintenance. Without preparation, trees can suffer from broken branches, stressed roots, fungal problems or poor regrowth in spring. By doing a few checks now, you protect both your garden and your property.
Step 1: Inspect Trees for Damage Before Temperatures Drop
A thorough inspection is the first step in any winter tree health checklist.
Look for signs of decay or loose branches
Examine the trunk and main branches for cracks, cavities, deadwood or peeling bark. Dead or weakened limbs can fall during winter storms, especially along Brighton’s windier areas such as Rottingdean, Ovingdean, Hove seafront and the higher points near the Downs.
Check for disease
Fungal growth, oozing sap, soft wood or unusual leaf patches can indicate underlying disease. Issues such as honey fungus are more common in damp conditions and should be handled early.
When to contact a professional
If you’re unsure about a branch’s stability, notice extensive deadwood or find disease symptoms, bring in a qualified arborist. A tree surgeon follows industry standards such as BS3998:2010, ensuring all work is safe and correct for the species.
Step 2: Protect Tree Roots Before Frost Arrives
Tree roots are the part of the tree most affected by frost. They sit close to the surface and are sensitive to temperature drops and excess moisture.
Mulch to insulate the root zone
Apply a layer of mulch around the base of your trees. This helps regulate soil temperature, improves moisture retention and shields roots from frost. Use materials such as compost, bark chips or leaf mould. Keep mulch a short distance from the trunk to avoid rot.
Improve drainage to stop waterlogging
Brighton’s clay patches and coastal soils can hold water. Heavy, saturated soil in winter can suffocate roots. If water gathers around certain trees, gently aerate the soil with a fork to help drainage.
Avoid compacting the soil
Walking repeatedly around the base of trees compacts the ground, restricting air flow. Use stepping stones or avoid that area where possible during the wetter months.
Step 3: Prune and Shape Trees Safely for Winter
Tree pruning helps remove risky branches and reduces resistance to strong winds. Done correctly, it helps trees go into winter in a stable and healthy condition.
Remove weak or crossing branches
These branches rub against each other, creating wounds that become entry points for disease during cold, damp weather.
Shape the canopy to reduce wind resistance
Areas close to the sea experience stronger gusts. Thinning the canopy helps wind pass through rather than forcing the tree to sway heavily.
Avoid heavy pruning
Some species are sensitive to pruning during winter. Light shaping and deadwood removal are usually enough unless tackling structural issues.
For larger or higher branches, always ask a professional to carry out the work. Winter safety risks are significantly higher when balancing on ladders or cutting heavy limbs.
Step 4: Support Young and Newly Planted Trees
Young trees need extra attention in winter because their roots and bark have not fully developed. A few simple precautions can help them stay healthy through the colder months.
Wrap or shield young trunks
Protect the bark by using breathable tree guards or hessian wraps. These provide gentle insulation and help young trunks cope with sudden drops in temperature.
Stabilise with proper stakes
Newly planted trees can move in strong winds, especially in exposed parts of Brighton. Check that the stakes are firm and that the ties are soft and flexible so they hold the tree securely without damaging the bark.
Look after the root zone
Young roots are sensitive to frost and excess water. Add a thicker layer of mulch around the base to keep the soil warm and help it retain moisture. Make sure the area drains well so the roots do not sit in water.
Step 5: Prevent Winter Pests and Common Tree Diseases
Pests and diseases don’t disappear in winter. Some actually thrive in damp conditions.
Watch for fungal infections
Honey fungus, canker and root rot can spread through old wood and wet leaves. Clearing debris reduces the risk.
Check evergreen trees for pests
Scale insects and overwintering aphids often settle on evergreen foliage during cold months. Early action prevents infestation later.
Improve airflow
A tidy garden with clear soil and healthy spacing between branches reduces the likelihood of fungal growth and pest sheltering.
Step 6: Prepare Surrounding Soil and Garden Beds
Healthy soil makes a noticeable difference to winter tree health.
Check drainage and soil structure
Waterlogged soil restricts oxygen and can damage fine roots. Loosen compacted areas and add compost where needed.
Use compost to stabilise soil temperature
A thin layer of compost helps keep temperature levels balanced and feeds the soil’s natural biology.
Remove heavy leaf layers
A thick layer of wet leaves stops air from reaching the soil. Add what you remove to a compost bin for spring use.
Step 7: Secure Trees Ahead of Brighton’s Winter Storms
Wind is one of the biggest threats to trees in Brighton during winter.
Identify high-risk branches
Branches hanging over paths, driveways or roofs should be inspected closely. Even small limbs can cause damage in a storm.
Thin dense crowns
Thinning or lightly shaping the crown reduces wind force and lowers the risk of breakage.
Check proximity to power lines
Never attempt to cut branches near overhead lines yourself. This must be managed by a qualified, insured professional following HSE guidelines.
Step 8: Responsible Winter Garden Waste Management
Once you’ve completed your winter preparation, proper disposal of waste is essential.
Compost small leaves and twigs
This provides free, nutrient-rich material for spring.
Use Brighton & Hove City Council’s green waste services
This is an eco-friendly way to handle large piles of leaves and branches.
Call a tree surgeon for heavy or diseased material
If branches are large, rotten or infected, they should be professionally removed to prevent spreading disease.
When to Call a Professional Tree Surgeon in Winter
You should call a professional if:
- Branches are too high or heavy to cut safely
- You notice signs of disease or decay
- Trees lean heavily after storms
- You’re unsure how to prune safely
- Your garden is close to seafront winds or steep slopes
