Fertilizer applications increase need for water. Apply fertilizers that contain slow release, water-insoluble forms of nitrogen. Use mulch to retain moisture in the soil. Mulch also helps control weds that compete with landscape plants for water. Once established, they do not need water as frequently and usually will survive a dry period without watering.
Group plants together, based on similar water needs.
Do not hose down driveways or sidewalks. Use a broom or blower to clean leaves and other debris from these areas. Use a shut-off nozzle on your hose, which can be adjusted down to a fine spray so that water flows only as needed. When finished, turn it off at the faucet instead of at the nozzle to avoid leaks. Check hose connectors to make sure plastic or rubber washers are in place.
