Winter Tree Watering Necessary During Drought Conditions

The Colorado State Forest Service (CSFS) - Colorado State University reports that nearly all of eastern Colorado is currently experiencing some level of drought.  Although trees in urban and community settings throughout this region remain dormant, they require occasional watering during dry winters to remain in top health.  The CSFS offers the following winter watering tips:  

  • Water when it’s warm. 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. Apply water to soak the entire area underneath the full span of a tree’s branches.
  • Water slowly. To ensure deep penetration, use a drip or soaker hose on 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 abundant spring precipitation arrives, be sure to continue watering every few weeks in the absence of snow and colder temperatures.

Tree Collections

The Town is pleased to announce their participation in the Tree Collections tool created by the Colorado Tree Coalition (CTC). The CTC launched its Tree Collections program to create a unique platform that links users to a network of diverse tree collections throughout the state, while also delivering consistent and comprehensive individual tree species information. Tree Collections is an educational tool for all seasons that can be utilized by students, curious visitors, nature lovers, and tree people alike.

Crescent Park and Arapahoe Ridge Park are currently within the Tree Collections’ database with more locations throughout Erie to be added in the near future. Visit to find a collection near you.
