A kitchen timer is a handy reminder for turning off sprinklers.
Don’t let the hose run while washing your car. Use a bucket filled with soapy water and an automatic shut-off nozzle on your hose. Use the hose just to rinse it off. Garden hoses can deliver over 10 gallons of water per minute.
Don’t water the gutter. Position your sprinklers so water pattern just covers the lawn or garden, not sidewalks, driveways, or gutters. Avoid watering on windy days.
Plant drought-resistant trees and plants. Many beautiful trees and plants thrive with far less watering than other species.
Put a layer of mulch around trees and plants. Mulch will slow evaporation of moisture and discourage weed growth, too.
Set lawnmower blades to 1-2 inches and keep them sharp to cut grass cleanly and retain moisture longer.
Set your sprinkler at a slow enough delivery rate for your lawn to absorb the water and prevent runoff. The average sprinkler uses 10 gallons per minute.
Tell your children not to play with the hose and sprinklers.
Use a broom, not a hose, to clean driveways and sidewalks.
Water your lawn only when it needs it. Deep soak your lawn, a light sprinkling tends to evaporate quickly and tends to encourage shallow root systems. Water early, before 10:00 am, to prevent growth of fungus.
