Registrations received after October 4, 2022 will be held for 2023 in anticipation of adoption of the budget proposal. Treatments are only effective when the trees are actively pulling nutrients through the trunk system (or in other words, when the trees are fully leafed out). Treatments can be performed every two to three years. This program is proposed again for the 2023 budget.
This fact sheet (pdf) has been provided by the Colorado State University Extension Office about insects and diseases affecting ash trees in the Grand Junction area.
The 2022 program registration window has closed.
Pending budget approval, we plan to bring this program back in 2023. Use this registration form to get on T4's list for evaluation in the late spring of 2023!
Noticed a decline in your tree’s health? You may have an Ash tree on your property. We are here to help! Ash trees make up 20% of Grand Junction trees, and pests are killing these trees at an alarming rate. We are teaming up with T4 Tree Service to deliver Grand Junction residents the opportunity to protect their Ash trees against these killer pests. Questions? Contact T4 Tree Service at 970-640-5284.
Trees are also evaluated for general health. Trees that are already showing signs of stress may not qualify. There is a $225 minimum fee for treatment (split 50/50 between the resident and the City). The City will pay up to $500 per address for treatments directly to T4. The resident will also pay their half directly to T4.
