Trees are amazing creations that enhance our daily lives. They provide the aesthetic qualities of beauty, color, and form; especially in our urbanized landscapes. Greeley loves trees. In fact, we have been a Tree City USA for over 30 years!
In order to keep Greeley green, we do the following:
Did you know that the City of Greeley has been a designated as a Tree City USA for 35 years? Join us in celebrating during the 2015 Greeley Tree Celebration. This free, family friendly event will take place in Lincoln Park on Saturday, May 2, from 9:00 a.m. to noon. The celebration includes informational booths, entertainers, hands-on activities for people of all ages, the Colorado State Forest Service mascot, and more.
Few tree services are authorized to work within 10 feet of energized lines. Contact us at 970-339-2405 with questions.
Trees are a significant, long-term investment in your property and the entire community. That investment should compliment your home and increase in value over time. Keep your trees strong and beautiful by following our tips below.
There are so many conditions that affect our landscapes. High winds, cold temperatures, high soil pH, low precipitation levels and heavy clay soils are just some of the factors that work against our landscapes.
Landscaping on public right-of-way is a privilege extended to Greeley residents by the City; however, that privilege carries with it the responsibility to obtain the proper planting permit and adherence to City of Greeley planting standards. Any tree(s) planted on public rights-of-way must be preceded with a landscape permit issued by the Community Development Department. Permit information is available on our planting permit page.
For pruning diagrams and to view technical fact sheets on pruning, visit Colorado State University. For interactive and fun pruning instructions and video, visit The National Arbor Day Foundation, and launch the pruning program.
Requests are received from citizens to inspect trees or shrubs on their property. A staff arborist then visits the site and advice is given concerning potential insect, disease, structural and/or cultural problems. Recommendations are then made toward corrective actions that should be taken to alleviate or prevent particular problems.
Every effort is made to provide advice or information by phone, mail or email at no charge. On-site consultations will be arranged around other duties, typically at no charge. Consultations may be performed by any of the qualified full-time staff, keeping in mind that it is very difficult for us to schedule appointments.

Many insects attack trees in only a secondary capacity. In other words, they are there because the plant has already been predisposed to a particular problem and is under a great amount of stress.
Two of Greeley's major insect pests, the European Elm Bark Beetle and the Spruce Ips Engraver Beetle, both attack trees under stress. The Elm Bark Beetle transmits Dutch Elm Disease and the Ips Beetle destroys Spruce. Just as preventative maintenance works with automobiles, plants free from insects and disease work the same way. Pay attention to proper watering practices, planting and pruning techniques, fertilization, and sound tree selection/placement.

Common Insects In Greeley
There is a difference between environmental and mechanical damage. However, understanding these important and basic tips can help you maintain control over these issues.
Sunscald happens during cold, bright days in winter. Young, thin-barked trees are most susceptible. During warm winter days, cells and tissues become activated. When freezing temperatures develop overnight, those cells freeze. Sunscald can be prevented. We recommend the use of commercial tree wraps, which are available at most garden centers and plant nurseries. Wrap trees from October through April. Begin at the base of the trunk and overlap wrap spiraling upward; secure at the first branch union with masking tape. Wrap trees at least the first two years after planting or transplanting. DO NOT leave wrap on all year round. This will restrict tree growth and increases chances for attack from disease and insects.
All plants can be injured by receiving too much water just the same as if they do not receive enough. Most insects and disease will not infest healthy trees. By not having the proper watering schedules for your particular landscape, your plants are susceptible to attacks from insects and disease. Basically, proper watering helps keep the plant's immune system working properly. If planning a new landscape or working with a fairly young landscape, utilize all resources available to discover what watering requirements are necessary for each plant. Mature landscapes offer little opportunity to re-design watering zones or schedules. Talk to a professional about making watering changes. Once a landscape adapts to a particular schedule, stress may be induced if that schedule is changed. Remember, ALWAYS water the ENTIRE year. During warm dry spells in the winter, drag out your hose and give your landscape a good soaking.
Frost damage occurs with both early Fall frosts OR late Spring freezes. Avoid heavy nitrogen applications to your landscapes after July. This will help your plants to begin dormancy and will not encourage new growth at an inappropriate time. Spring freezes typically cause more noticeable damage than fall. This is a time of strong growth. Frost injuries can be difficult to prevent; however, ideally you should plan to use plants that fit our climate and hardiness zone. Be wary when using tender plants; they will need proper protection according to their growth habits and requirements. Each plant has its own micro-climate in which it will perform better.
This damage is easily prevented. Ideally, you need to maintain a "tree ring" around the base of each tree. You can do so effectively with herbicide (weed and grass) destroying chemicals. Carefully prune all basal sprouts and suckers off of the tree before applying chemicals. Providing this ring around trees helps to eliminate the need for weedeaters and lawnmowers to get too close to the base of the tree, doing fatal damage. Also, shrubs and shrub beds should be isolated from turfed areas. Do so with edging materials of your choice, and place a wood chip mulch inside your shrub bed.
This damage occurs from the improper use of chemical weed and pest controls. Diagnosis of the problem is not always simple. A complete history of maintenance practices and technical information is needed to properly diagnose the problem

We offer a program in which select unwanted trees can be donated to the Parks system. This is done at no cost to the donor.
Additionally, we can help you commemorate a loved one by planting a tree in a park of your choice.
