14 Ways to Save Water in Your Garden
Grow drought-tolerant plants
Once established, drought-tolerant plants can handle extended periods without water. That's not to say they don't need water, just less than other garden plants. A layer of mulch keeps them even happier by maintaining soil moisture and temperature.
In the Midwest, try plants such as sedum (left) (Sedum spp.), ornamental grasses, black-eyed Susan (Rudbeckia spp.), goldenrod (Solidago spp.), sage (Salvia spp.) and yarrow (Achillea spp). Check with your local garden center to see what's best for your area.
