Making your garden water-wise
Add plenty of organic matter such as compost and manure to the soil to improve water retention, plant health and soil structure. This is one of the most important steps in making your garden drought-tolerant. Remember, the healthier your plants are, the more likely they are to withstand drought conditions.
Install a rainwater tank. It is recommended that water from these tanks be used for gardens only. These tanks are expensive and owners are responsible for maintenance. Your local water company will be able to provide you with information on whether a rainwater tank would be efficient in your area.
Recycle water on your garden from your shower or washing machine. It is legal (under certain conditions) to recycle this water, known as greywater, on your garden, but you must have approval from your local water company and a licensed plumber must connect your system to your plumbing.
Remove weeds regularly from garden beds because weeds compete with other plants for water.
Before planting a new garden bed, condition clay soils with powdered or liquid gypsum to improve water penetration.
