Aerate the lawn and fill the holes with compost so the water can infiltrate deeper
Attach a water efficient spray nozzle to your hose and use it to mist your lawn to build up humidity for a few minutes at the end of the day.
Check with your local water agency for possible rebates on low water usage irrigation products
Do not use high nitrogen fertilizers during a drought. They encourage growth but the plants will need more water
Fix or replace any broken sprinklers and repair leaks
If you intend to prune, do so before April or don't prune. Pruning stimulates growth, which needs more water. Existing growth will also provide additional shade to the soil, helping to retain moisture
Keep your lawn as healthy as possible. A healthy lawn will survive better. Many lawns can go very dry and still come back
Mow grass (Fescue, Rye, Kentucky Blue Grass) higher (3 inches to 3.5 inches) to promote deeper root growth and hold more moisture
Mulch heavily all flower and soil beds. Mulch helps keep water in the soil. Do not use rocks/gravel because they add heat to the soil and moisture evaporates faster
