Tree care tips for every season
Trees improve gardens, support wildlife and help the local climate — but they need seasonal attention to stay vigorous and safe. Use these practical tree care tips for every season to protect growth, prevent disease and reduce the risk of storm damage.

Spring: prepare for a season of growth
Spring is the best time to reset after winter and set trees up for healthy growth.
- Check for winter damage: Inspect trunks and branches for splits, cracked bark or broken limbs that may have occurred over winter. Damaged limbs can rot or harbour pests if left unattended.
- Prune selectively: Remove dead, diseased or rubbing branches to improve structure and airflow. Spring pruning encourages healthy canopy development but avoid heavy cuts on species that bleed sap heavily in spring.
- Apply mulch: A 5–10cm layer of organic mulch helps retain moisture, regulate soil temperature and suppress weeds. Keep mulch a few inches clear of the trunk to prevent rot and rodent damage.
- Fertilise carefully: Use a slow-release fertiliser formulated for trees to replenish nutrients as buds break dormancy. Focus on nutrient-poor soils or trees showing slow growth.
Summer: manage heat, drought and pests
Warm weather accelerates growth but also increases stress from heat and moisture shortages.
- Water deeply: During dry spells, water deeply and slowly to encourage deep root development. Short, frequent watering promotes shallow rooting and greater drought vulnerability.
- Monitor pests and diseases: Check foliage and bark regularly for discolouration, unusual growths or feeding damage. Early detection makes treatment simpler and more effective — consult a tree surgeon for infestations or persistent issues.
- Protect young trees: Newly planted or juvenile trees are most vulnerable to heat stress. Provide temporary shade or protective shelters and ensure stakes support movement without restricting growth.
- Check supports: Stakes and ties should stabilise without chafing bark. Remove or adjust supports as the tree establishes to avoid girdling.
Autumn: harden off and prepare roots for winter
Autumn is a strategic time to prepare trees for dormancy and to plant new specimens.
- Clear leaves: Remove garden leaves from lawns and around root collars to reduce fungal risk and prevent smothering of ground-level vegetation.
- Fertilise for root development: A targeted slow-release feed in autumn can support root growth and help trees store energy for winter dormancy.
- Book inspections: Arrange a professional tree survey before winter storms. A tree surgeon can identify structural weaknesses and recommend pruning or bracing.
- Planting window: Cooler, wetter autumn conditions are ideal for establishing new trees — roots can grow before ground freezes, giving young trees a head start.
Winter: safety, structure and dormancy care
Although trees are dormant, winter demands thoughtful care to reduce seasonal damage and maintain structure.
- Protect trunks: Wrap vulnerable or young tree trunks with hessian or tree guards to reduce frost cracks and bark damage from wildlife.
- Prune structurally: Winter offers the clearest view of a tree’s framework. Remove dead or hazardous branches and correct structural defects while the canopy is leafless.
- Manage snow and ice: Gently brush off heavy snow from branches to reduce breakage. Avoid forceful shaking that can snap brittle limbs.
- Seek professional help: If a tree shows signs of decay, large split limbs or dangerous lean, engage a qualified tree surgeon rather than attempting risky work yourself.
Practical, year-round maintenance
Consistent, seasonal attention keeps maintenance costs down and preserves tree value.
- Observe regularly: Walk the garden each season to spot early signs of disease, pests or structural faults.
- Match care to species: Different species have different pruning times and tolerance to feeds and water — tailor care accordingly.
- Focus on roots: Avoid soil compaction around root zones and keep turfmowers and heavy equipment well away from root collars.
- When to call a professional: For large removals, complex pruning, suspected disease or emergency storm damage, contact a qualified tree surgeon. See our guide on signs it’s time to call a tree surgeon for help identifying issues and arranging safe remedial work.
Why healthy trees matter
Healthy trees deliver tangible environmental and social benefits beyond their visual appeal.
- Improved air quality: Trees absorb carbon dioxide and airborne pollutants while releasing oxygen, helping to cleanse urban and rural air.
- Wildlife habitat: Trees provide food, shelter and nesting sites for birds, insects and mammals, supporting biodiversity.
- Soil conservation: Root systems stabilise soil and reduce erosion and surface runoff, which is important on sloped sites.
- Climate regulation: Strategic tree cover cools urban areas, provides shade and contributes to local microclimate moderation.
