The City of Arvada is home to a diverse and beautiful array of wildlife and plants. Trees are a major part of the City’s infrastructure, providing both beauty and supporting vital ecosystems. Our goal is to help promote and preserve Arvada's urban forest.
Topic Spotlight: Emerald Ash Borer
Emerald Ash Borer (EAB) is an invasive insect that has killed more than 50 million Ash trees in 30 states since the initial discovery in 2002. A recent survey shows that Arvada has nearly 2,000 Ash trees growing on public property. The Arvada forestry division along with other metro forestry divisions is working on management plans to deal with this invasive insect.

What You Can Do
Making sure your trees stay hydrated and donating or planting a tree in partnership with the City are great ways to support the City's tree population.
Deep Water Your Trees
- Trees should be watered every 3-4 weeks even throughout the winter months.
- Special attention should be given to evergreens such as Spruce, Pines and Firs and all trees planted within the last 3-5 years.
- Water when temperatures are above 40 degrees and during mid day so the water has a chance to soak in.
- Apply water out to the drip line (the area around the trunk out to under the outer most branches).
- A general rule is to apply 10 gallons of water for each diameter inch of tree trunk measured 6" above the ground.
- If using a water probe or needle do not go down more than 8-10". Going deeper will put much of the water under the root system. It is also important to close all holes so the water is not wicked out.
Apply Landscaping Mulch
To help reduce soil evaporation, improve water absorption, insulate against temperature extremes and reduce weed growth, apply between two and four inches of wood chips around the base of the tree, but not touching the tree trunk.
Free Mulch (Subject to Availability)
Free wood chip mulch is available at the City of Arvada Parks Maintenance facility, 7800 West 62nd Avenue, Monday through Thursday, 6:30 a.m. to 3:30 p.m and on Friday from 6:30 a.m. to noon. While the mulch is free, loading and transporting mulch is the recipient’s responsibility.
To check availability, please contact Parks Maintenance at 720-898-7410.
Plant a Tree
The City of Arvada Plant A Tree Program is designed to inspire our residents and promote the planting of trees in the city's parks and open spaces; as a rewarding and unique means of paying tribute, honoring, commemorating or celebrating special times.

Donate a Tree
If you have a tree on your property that is in the way of construction or has outgrown its present location, the City of Arvada's forestry division will consider transplanting it to one of Arvada's many parks.
We will visit your site to determine if the tree is suitable to be moved. Donations to the City are tax deductible.
