Tree Maintenance in Spring: A Guide for Melbourne Residents

Spring in Melbourne is a time of renewal and growth. As trees awaken from their winter dormancy, it's essential to provide them with the care they need to thrive through the warmer months. This article outlines the crucial tree maintenance tasks that should be undertaken in spring, with a special focus on when to consult a professional arborist.

Why Spring is the Ideal Time for Tree Maintenance

Spring is the season when trees begin to grow actively, making it an ideal time for maintenance. The warmer temperatures and increased daylight hours stimulate new growth, and the soil is typically moist from winter rains, providing an excellent environment for root development. This period of vigorous growth allows trees to recover more effectively from pruning and other maintenance activities.

Understanding Melbourne's Unique Climate

Melbourne's climate is characterised by its unpredictable nature, with a mix of warm and cool days throughout the spring season. This variability can impact tree health, making it even more important to carry out timely maintenance. The average temperatures in Melbourne during spring range from 10°C to 20°C, with occasional frosts still possible in early spring. These conditions necessitate a careful approach to tree maintenance to ensure the long-term health and vitality of your trees.

Essential Spring Tree Maintenance Tasks

1. Pruning

Pruning is a critical task in spring, as it helps to shape the tree, remove dead or damaged branches, and encourage healthy growth. During spring, focus on the following:

  • Removing Dead or Diseased Branches: Identifying and removing these branches early in the season prevents the spread of disease and reduces the risk of pests.

  • Shaping the Tree: Light pruning to shape the tree and remove any crossing branches can improve the overall structure and aesthetics.

  • Encouraging New Growth: Strategic pruning can stimulate new growth, particularly in flowering trees, enhancing their bloom potential.

It’s essential to avoid over-pruning during spring, as excessive removal of foliage can stress the tree and inhibit its ability to photosynthesise effectively.

2. Mulching

Applying mulch around the base of your trees is an excellent way to conserve moisture, regulate soil temperature, and suppress weeds. In Melbourne, where spring rains can vary, mulching ensures that the soil retains adequate moisture, supporting healthy root development.

  • Choose Organic Mulch: Organic mulches, such as wood chips, bark, or compost, are ideal as they break down over time, enriching the soil with nutrients.

  • Proper Application: Apply a 5-10 cm layer of mulch, ensuring it does not touch the tree trunk directly, as this can lead to rot and pest issues.

3. Fertilising

Spring is the perfect time to fertilise your trees, providing them with the nutrients they need for robust growth. Melbourne’s soils can sometimes be nutrient-poor, particularly in urban areas, making fertilisation crucial.

  • Selecting the Right Fertiliser: Use a slow-release fertiliser that is balanced in nitrogen, phosphorus, and potassium. Trees with specific deficiencies may benefit from targeted fertilisers.

  • Application Tips: Apply fertiliser around the drip line of the tree, where the roots are most active, and water it in thoroughly to ensure even distribution.

4. Watering

While Melbourne typically experiences some rainfall in spring, it's important to monitor soil moisture levels, especially during dry spells. Trees require consistent watering to support new growth.

  • Deep Watering: Watering deeply but infrequently encourages the development of deep roots, which are more resilient during dry periods.

  • Check Soil Moisture: Regularly check the soil moisture by digging a small hole near the tree’s root zone. If the soil is dry at a depth of 10 cm, it’s time to water.

5. Pest and Disease Monitoring

Spring’s warmer temperatures and increased humidity can lead to a surge in pests and diseases. Early detection and management are key to preventing significant damage.

  • Inspect Regularly: Check your trees for signs of pests such as aphids, scale insects, or caterpillars, and for diseases like powdery mildew or rust.

  • Use Eco-Friendly Solutions: Where possible, use organic or eco-friendly pest control methods, such as neem oil or insecticidal soap, to minimise harm to beneficial insects.

Consulting an Arborist

When to Seek Professional Help

While many tree maintenance tasks can be handled by homeowners, certain situations call for the expertise of a professional arborist. Consulting an arborist in the following scenarios can ensure the safety and health of your trees:

  • Large or Mature Trees: Pruning large or mature trees can be dangerous without the proper equipment and knowledge. An arborist has the skills to safely prune these trees, reducing the risk of injury or property damage.

  • Tree Health Concerns: If your tree shows signs of disease, decay, or abnormal growth, an arborist can diagnose the issue and recommend appropriate treatment.

  • Complex Root Systems: Trees with extensive or complex root systems may require specialised care, particularly in urban environments where root damage from construction or compacted soil is a concern.

  • Heritage or Protected Trees: Trees protected under local laws, such as those in Merri-bek or Banyule City Council areas, may require specific permits for pruning or removal. An arborist can help navigate these regulations and ensure compliance.

Choosing the Right Arborist

When selecting an arborist, consider the following:

  • Certification and Experience: Look for an arborist certified by a recognised body, such as Arboriculture Australia, with experience in the types of trees common in Melbourne.

  • References and Reviews: Ask for references and check online reviews to ensure the arborist has a good reputation for quality work and customer service.

  • Insurance and Compliance: Ensure the arborist has adequate insurance and adheres to local regulations, particularly if working on protected trees.

Regular consultations with an arborist can provide numerous benefits, including:

  • Early Detection of Issues: An arborist can identify potential problems before they become severe, saving you time and money in the long run.

  • Expert Pruning and Care: Professional pruning can enhance the health and appearance of your trees, promoting longevity.

  • Peace of Mind: Knowing that your trees are in expert hands provides peace of mind, particularly during stormy spring weather when tree damage is more likely.


Spring is a critical time for tree maintenance in Melbourne. By undertaking essential tasks such as pruning, mulching, fertilising, watering, and monitoring for pests, you can ensure that your trees thrive throughout the growing season. However, for larger, more complex, or protected trees, consulting a professional arborist is the best way to ensure your trees receive the care they need. With the right approach, your trees will not only survive but flourish, adding beauty and value to your property for years to come.
