Healthy soil saves you water

Amending your soil is key to creating a Water Wise lawn. Colorado soils are naturally low in organic matter - the dark material that creates the rich, fertile soil which traditional lawns love. To add organic matter to your soil, rototill about an inch of an approved soil amendment six inches deep, before installing sod or seed. Doing this will help you save up to 25% of the water your new grass will need and creates a greener, healthier lawn.

• Use the right soil amendment. Lots of different types of soil materials are available, but only amendments high in organic matter will hold more water in the soil. Topsoil and tri-mix are not soil amendments and are best used when an area needs additional soil, not more organic matter. Please consult our list of approved soil amendments.
• New lawns require an establishment permit. This allows you to temporarily water new sod or seed during the day and more frequently than three days per week. It’s valid for 28 days for sod and 42 days for seed projects.
• Keep and submit your approved soil amendment receipt as part of your establishment permit application. New lawns started from sod or nonnative seed require soil amendments as this is the responsible way to grow a Water Wise lawn in our climate. Four cubic yards per 1,000 square feet is are required.
• Water wisely when establishing new landscapes. New sod or seed needs water multiple times per day. As its root system grows stronger, it can be watered less often. To learn more, check out the suggested watering schedule.
• Long-term success. After your establishment permit expires, follow these sprinkler scheduling and horticultural tips. These tips will add to your water saving potential and set your new lawn up for long-term success.
