Spring Water Saving Tips

Be mindful of your water usage when planting new trees and shrubs.

Avoid over-watering by utilizing a slow drip irrigation system.

Mix mulch with your soil to reduce evaporation, promote plant growth and control weeds.

Remove as many weeds as you can; they compete with other plants for your water.

Use a moisture meter to see if plants need water; most plants can die from overwatering.

Avoid evaporation by watering late at night or early in the morning when temperatures are at their lowest.

Install a Weather Based Irrigation Controller which monitors changing weather conditions to prevent unnecessary watering. Check for rebates from your local water agencies.

Minimize overspray by adjusting your sprinklers; often a simple adjustment to your irrigation heads can reduce or eliminate overspray.
