Lower your water consumption by installing and using a subsurface drip irrigation system instead of watering your garden by hand or with sprinklers.
Subsurface drip irrigation is a low-pressure, high-efficiency irrigation system that uses buried drip tubes or drip tape to water your garden. With sub surface drip irrigation, surface water evaporation becomes a thing of the past and you may enjoy less weeds, as water is applied directly to the root zone rather than to the soil surface where most weeds grow.
The process reduces the amount of water and fertiliser needed. To improve your garden’s water retention even more, use mulch and try replacing any hard surfaces you can with more permeable surfaces to avoid stormwater runoff.
An easy way to preserve water when renting is to water your garden in the early morning or evening to minimise evaporation.
