Summer in Canberra brings challenging conditions, with hot, dry winds and intense heat. Here are practical steps to help your garden thrive through these harsh months.
Mulch
Mulch reduces evaporation and keeps roots cool.
Mulching is an effective way to conserve moisture and keep soil cool. Spread 5–7 cm of mulch around plants and trees, extending it to the drip line (the widest branch area). Mulch reduces evaporation, regulates soil temperature, and suppresses weeds.
Deep Watering
Young trees are particularly vulnerable to heat. Deep water them out to the drip line to strengthen root systems and ensure the water reaches critical roots.
Drip Irrigation
Drip irrigation systems or soaker hoses deliver water directly to plant bases, reducing waste and encouraging deep root growth. This efficient method is ideal for conserving water during Canberra’s dry summers.
Choose Drought-Tolerant Plants
Opt for drought-tolerant species, natives, succulents, or plants adapted to Canberra’s climate. These require less water and maintenance, making them resilient and eco-friendly.
Monitor Soil Moisture
Use a soil moisture meter to track hydration levels. This prevents overwatering and ensures plants receive water when needed, especially on windy, hot days when they dry out faster.
Water Wisely
Water in the early morning or late evening to reduce evaporation. Avoid watering during the heat of the day, as it wastes water and can scorch plants exposed to direct sunlight.
Shade and Wind Protection
Provide temporary shade for delicate plants during extreme heatwaves. Windbreaks or shade cloths can protect plants from hot, drying winds.
