The Margaret River region is home to a stunning and diverse tree canopy dominated by eucalypts, Corymbia calophylla, Agonis flexuosa, and Melaleuca species. These native trees thrive in the Mediterranean climate of the South West, benefiting from mild winters, long rainy seasons (mid-autumn to late spring), and warm, sunny summers.
However, with the challenges of climate change and increasingly frequent droughts, tree care has never been more important. Here’s how to care for your trees year-round and ensure their health and longevity.
Why Trees Thrive in Margaret River
The unique Mediterranean climate provides an ideal environment for rapid tree growth. Unlike deciduous trees that shut down in winter, native eucalypts and under storey species grow continuously when the soil retains water. This extended growing period helps them develop robust canopies and deep root systems. However, sustained drought can put even these hardy species under stress, reducing their ability to thrive.

When is The Best Time to Prune Trees
Timing is everything when it comes to pruning. In Margaret River’s climate, pruning is best done during growth periods when the tree has the energy to heal wounds effectively. For eucalypts, this can be nearly year-round, provided they are not under drought stress.
The key to successful pruning is understanding the tree’s healing process:
Healing through compartmentalisation: After a cut, trees form a tough internal wall of tissue around the wound to seal it. This process, driven by phytohormones and cell division, protects the tree from pathogens and ensures nutrient flow between the roots and canopy.
Eucalypts: Natural healers: Eucalypts, particularly Eucalyptus camaldulensis, are exceptional at healing wounds. They are highly resilient when pruned at the right time.
Seasonal Tree Care Tips for Margaret River Trees
Autumn:
Check for overgrown branches and deadwood as the rains begin.
Prune during this period of active growth to allow the tree time to heal before summer stress.
Winter:
Monitor soil moisture levels; winter rains help trees recover from summer drought.
Avoid heavy pruning during waterlogged conditions, which can increase the risk of pathogen spread.
Spring:
A prime time for pruning! The combination of warm weather and ample moisture boosts the tree’s ability to heal.
Encourage new growth by removing dead or weak branches.
Summer:
Limit pruning during extreme heat or drought conditions when trees are under stress.
Focus on maintenance tasks like mulching to retain soil moisture.
Climate Change and Its Impact
With more frequent drought conditions, many native trees in the South West face challenges they’re not adapted to handle. Proactive care, such as regular tree pruning, mulching, and soil management, can help trees withstand these stresses and maintain their health over time.

Key Takeaways
Prune trees during their growth stages to optimise wound healing.
Eucalypts grow year-round unless under drought stress, making them ideal candidates for careful pruning.
Tree care is about more than cutting—healthy trees depend on hormonal responses and cell division to seal wounds and prevent infection.
Following these seasonal tree care tips, can help you keep your trees healthy and thriving in the lush but challenging environment of the Margaret River region.
