January Gardening Guide for Temperate Australia
January in the Garden: Surviving and Thriving in Extreme Aussie Heat
January in much of Australia means one thing: extreme heat. Temperatures regularly soar into the 40s (degrees Celsius), testing the resilience of even the toughest gardens. While the focus is often on watering and shade, there are other strategies to help your plants not just survive, but even thrive during this challenging month. This guide offers diverse tips for managing your garden in the January heat.
How to Create Microclimates:

Instead of solely relying on shade cloth, consider creating microclimates within your garden. These small areas offer varied conditions, providing refuge for plants sensitive to extreme heat:
Dense Planting: Planting densely creates shade and reduces soil temperature. Use taller plants to shelter smaller ones.
Vertical Gardening: Walls and fences can radiate heat. Use vertical structures like trellises or espaliered fruit trees to create shaded areas.
Water Features: Even a small pond or bird bath can cool the surrounding air through evaporation. Don’t forget the bees!
Soil Health: The Foundation of Heat Resistance
Healthy soil is better equipped to handle heat stress. Focus on:
Soil Biology: Healthy soil teems with beneficial microbes that help plants access nutrients and water. Avoid using synthetic fertilisers, which can harm soil life. Instead, use compost and worm castings.
Improving Soil Structure: Well-structured soil holds moisture better. Add organic matter like compost, aged manure, or biochar to improve water retention and drainage.
Soil Testing: If you are unsure about your soil health, a soil test can give you valuable information.
Beyond Watering: Moisture Management Strategies
While deep watering is important, consider these additional strategies:
Wicking Beds: These beds have a water reservoir at the bottom, providing a constant supply of moisture to the roots.
Ollas: These porous clay pots are buried in the soil and filled with water, slowly releasing moisture to the surrounding plants.
Greywater Use (with caution): If permitted in your area, carefully use greywater from showers or laundry (excluding rinse cycle water) to water trees. Ensure it is treated correctly and does not contain harmful chemicals.
Plant Selection: Choosing Heat-Hardy Species
Selecting the right plants is crucial for surviving extreme heat. Consider these options:
Native Plants: Australian native plants are well-adapted to the local climate and require minimal watering once established.
Mediterranean Plants: Plants from Mediterranean climates, such as rosemary, lavender, and olives, are also drought-tolerant.
Succulents: These water-wise plants store water in their leaves and stems, making them ideal for hot, dry conditions.
Beyond the Garden: Protecting Your Property
With extreme heat comes increased fire risk. Take these precautions:
Clear Dry Vegetation: Remove dry grass, leaves, and twigs from around your house and garden.
Maintain Gutters and Roofs: Clean gutters and roofs to prevent the accumulation of flammable debris.
Watering Lawns Strategically: Keeping your lawn green can act as a fire break, but water efficiently.
Indoor Activities:
Seed Saving and Sorting: Organise your saved seeds and plan for future plantings.
Tool Maintenance: Clean, sharpen, and oil your gardening tools.
Propagation: Take cuttings of your favourite plants to propagate new ones.
Specific Advice for Western Australia:
Western Australia experiences some of the most extreme heat in Australia. In areas like the south west, while temperatures may not reach the same extremes as inland areas, it is still crucial to conserve water and protect plants from the sun.
Bushfire Preparedness: This is a vital concern for many parts of WA. Check fire danger ratings and have a bushfire survival plan in place. Always have a go-bag ready in the house and car. Make sure your family know your plan in advance and don’t forget to include your animals!
By implementing these diverse strategies, you can help your garden not just survive but even thrive during the extreme heat of January. Remember to observe your plants closely and adapt your approach as needed.
