We have welcomed the rainfall in March, which was over 137% of the long-term average and led to a slight increase in groundwater levels. However, the first two months of the new year were much drier than average in our central region and groundwater sources remain below average.
Groundwater is more likely to be replenished from rainfall during autumn and winter, when there is less plant growth and evaporation. October to March is the critical recharge period when rainfall is expected to reach the aquifers (porous rock where groundwater is stored), which are used for 60% of supplies.
How we can help
There are simple steps that every one of us can take – whether a householder, business, community or a council.
Planting season is now upon us and the best way to save water throughout the summer is to create a water efficient garden. Here’s how:
- Choose plants that thrive in dry conditions, such as Alyssum, Geraniums, French and African Marigolds, Petunias, Aquilegia, Campanula and Heuchera lavender.
- Look for the full sun symbol on the plant labels when buying new plants as this indicates their tolerance to dry conditions.
- Move containers, hanging baskets and pots into shady areas where possible
- If you’re potting up or planting containers, use ones made from plastic, glazed terracotta or wood. These tend to lose less water than bare terracotta
- When potting up your planters use a small amount of gel crystals. They absorb water and can help retain the moisture in the soil
- Use mulches like bark chips or gravel to retain moisture and keep weeds down.
- Water your plants using a watering can, either early in the morning or during the evening when it is cooler and there is less chance of water evaporating
- A water butt is a great way to collect rainwater, you can use it to water your garden or wash the car
