The Colorado Front Range is naturally a semi-arid, shortgrass prairie that would have few trees without irrigation. Growing trees here is difficult in wet years, not to mention the challenges in drought years. Properly placed and maintained trees are an asset to the environment and to our community.
Growing Season Watering Tips (April- October)
- Check the soil moisture at least once a week by digging down 4-inches, approximately 20” from the base of the tree. If the soil is dry, then soak well.
- Water approximately 10 gallons per inch of trunk diameter, two times a week. For an established or mature tree, water 15 gallons per inch of trunk diameter two times per week. Tips on tree watering in a drought
- We recommend watering slowly with a garden hose. Time how long it takes to fill a one-gallon container and multiply that time by 15 for a newly planted tree. Usually it’s around one gallon per minute.
- The most important area to water for deciduous trees is within the dripline (from the trunk to the outer edges of the trees branches). For evergreens, water three to five feet beyond the dripline on all sides of the tree.
- Maintaining mulch helps retain soil moisture.
- Avoid constantly saturated soil and begin to taper watering off during the fall.
