Be a water miser
1 Install a rain barrel to capture water from
eavestroughs.
2 Control weeds, which compete with garden plants for moisture.
3 Mulch to slow evaporation from the soil, cool the surface and discourage weeds.
4 Repair any leaks in couplings, hoses and sprinklers.
5 Grow drought-tolerant plants native to your region, and group those with similar watering requirements.
6 Recycle water from dehumidifiers, air conditioners and household grey water.
7 Position sprinkler heads to reach target plants and avoid paved areas.
8 Add organic matter such as compost and shredded leaves to improve texture and the water-holding capacity of all soils.
9 Stop watering when runoff occurs.
10 Invest in rain sensors and moisture meters for watering systems.
