Planting Strategies for Resilience:
Grouping Plants by Water Needs: When planning your garden, group plants with similar water requirements together.

Mulching: Apply a layer of organic mulch around your plants to conserve soil moisture, reduce evaporation, and suppress weed growth.
Efficient Watering: Utilise soaker hoses or drip irrigation systems to deliver water directly to the root zone, minimising wastage. Water deeply but less frequently to encourage deep root growth.
Soil Improvement: Enhance your soil's water-holding capacity by incorporating organic matter like compost. Healthy soil supports plant growth and resilience during drought.
Research alternative growing methods, such as wicking beds, also called sub-irrigation beds, are a water-efficient gardening and growing system designed to maintain consistent moisture for plants while minimising water wastage. These beds are particularly useful in areas with low rainfall or for individuals who want to conserve water in their gardening practices.
Use of wetting agents: Perlite, Vermiculite and Hydrogel crystals can be mixed into the soil to help retain moisture and reduce the frequency of watering.
Rain Barrels: Collect rainwater from your roof in barrels or containers and use it for watering your garden. This reduces reliance on municipal water sources. It is amazing what can be collected even from a bucket catching morning dew run off.
