Urban Forestry (Trees)

Trees overhanging power lines: Removing limbs from power lines is extremely dangerous. Please contact Xcel Energy by calling 1-800-895-4999. More info at my.xcelenergy.com/customersupport/s/article/Can-I-prune-my-tree-myself.

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.

What You Can Do for Your Trees

Assess the health of your tree and provide maintenance as needed.

Signs of a healthy tree

  • New growth: A healthy tree produces new growth yearly on both its trunk and branches.
  • Healthy branches: Branches should show signs of leaf budding and/or new growth
  • Strong bark: Healthy bark is free of fungi, large holes and cracks.
  • Plenty of leaves for deciduous trees; plenty of needles for evergreens.

Tips for maintenance

  • Prune dead, dying or broken limbs.
  • Inspect for insect damage or disease. If signs are present, contact a tree specialist for treatment options.
  • Deep water trees year round (in warmer temps)
    • 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 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

The Parks Department provides free mulch to residents when it is available. Mulch can be picked up in the parking lot at the Disc Golf Course at 17925 West 64th Parkway just east of Highway 93 on 64th Avenue below the Arvada Blunn Reservoir. You load. You haul.
