Trees in urban and community settings throughout the state are dormant now, but still require occasional watering during dry winters to remain in top health.
Vince Urbina, urban and community forestry manager for the Colorado State Forest Service, says both established and recently planted trees in Colorado — especially at lower elevations — often require additional watering in the winter months during extended dry periods i.

The best time for winter watering is on days when snow has melted off and the temperature is above 40 degrees.
Water a wide area. Tree root systems may spread much wider than the height of the tree, with most absorbing roots in the top foot of soil. Water slowly. To ensure deep penetration, use a drip or soaker hose on a low setting or soft spray wand to apply water slowly to the full area at the rate of 10 gallons per inch of tree diameter. Retain mulch. To retain soil moisture and save water, apply 4 inches of organic mulch onto bare soil within 2 to 3 feet from the base of the trunk, but not directly against the trunk.
Repeat as necessary. Until spring precipitation arrives, be sure to continue watering every few weeks in the absence of snow and colder temperatures. Type your address or the city or town where you live into the search field on this map.
