Leaves have fallen and gardens have been put to rest, but our landscape still needs our attention – especially during Colorado’s dry winter months. Even though plants are sleeping, their roots remain active whenever soil temperatures rise above freezing. Trees, shrubs, and perennials all benefit from supplemental watering during colder months which will help keep them healthy until spring.

Colorado’s low humidity, limited precipitation, and freeze-thaw cycles throughout the winter months can quickly dry out our soil. Maples trees, evergreens, and newly planted trees and perennial gardens are especially susceptible to drought injury during winter. Keep in mind that a plant may not show obvious signs of drought injury until spring or early summer.

A little care now helps your landscape stay healthy, resilient and ready for spring growth.

DO:

• Water by hand or with a hose end sprinkler attachment.
• Water slowly and deeply once every two weeks during extended dry periods when air temperatures are above 40 degrees with no snow cover.
• The best time to water is mid-day so water can soak into the soil before potential freezing at night.
• Apply a layer of mulch to your perennial gardens and trees. This helps the soil retain moisture and protects the root system.

DON'T:

• Do not turn on your irrigation system. Sudden freezes can result in damaged pipes and valves.
• Don’t water when temperatures are below 40 degrees.

Highlands Ranch Water provides residential customers an additional 1,000 gallons of water per billing period during the winter to support responsible winter watering and help protect your landscape investment.
