Tree Planting Guidelines during Drought
Trees benefit our community in numerous ways. In addition to providing beauty, they cool our homes and streets, reduce heating and cooling costs, sequester carbon, filter air pollution, reduce storm water run-off, and provide food and habitat for wildlife.
Before planting trees during a drought, it’s important to understand not only the benefits of trees, but also the challenges with keeping them alive and healthy during times of watering restrictions. The following guidelines should be reviewed and evaluated as you consider tree planting at this time:
- Newly planted two-inch trees require approximately 20 gallons of water each week during the growing season (April-October) and the same amount every two to three weeks during the dormant season (November-March) to provide adequate moisture.
- Watering restriction this year will most likely allow for only hand watering of trees.
- Now more than ever, it’s important to assure “the right tree in the right place”. Consider planting xeric trees and make sure there is adequate room for the tree to grow to maturity. Check planting guidelines and permit requirements prior to planting on the public right-of-way. Information regarding permits (which are required for planting along the public right-of-way) can be obtained by calling 720-913-0651.
- Additional information regarding guidelines can be found on the Community Tree Alliance (a coalition of local forestry and tree care professionals) at www.watersaver.org. Information regarding permits (which are required for planting along the public right-of-way) can be obtained by calling 720-913-0651.
- Proper planting is essential. Many trees are planted too deeply. Refer to proper planting guidelines to increase your chances of a successful transplant. Information can be obtained at www.denvergov.org/Forestry website.
- Amending the soil with compost improves soil texture and retains soil moisture. Amend the backfill at a ratio of one part compost to three parts native soil. Refer to above websites for additional information.
- Mulch placed at a depth of four inches over the root zone will also help to conserve valuable soil moisture. Mulch is readily available at no cost. Refer to above websites for additional information.
Denver Water may restrict tree planting under severe drought.
