Welcome to Fort Collins, Colorado, an annual Tree City, USA award recipient for the last 33 years. Our staff prides itself in its commitment to maintaining our urban forest. The Forestry staff, within the Forestry Division, maintains more than 40,000 city property trees.

FREE Mulch Available to Residents

The City of Fort Collins Forestry Department is offering free mulch to the public at the Streets Department (625 Ninth Street) located on the southwest corner of Lemay Avenue and Vine Street.

The mulch will be available for distribution during daylight hours only starting on Thursday, July 13 until the mulch is gone.

Residents will be required to load their vehicles so please come prepared with a shovel, gloves and, if necessary, some type of container to hold the mulch. This offer is not available to commercial businesses.

Until the mulch pile at the Streets facility is gone, the regular mulch sites located at the Timberline Recycling Center and Gardens on Spring Creek will not be stocked.

Invasive Insect Alert: Emerald Ash Borer (EAB)

This small beetle, originally from Asia, is responsible for killing over 50 million Ash trees in the United States. Many Eastern and Midwestern municipalities have lost nearly all of their Ash trees due to this deadly pest. Emerald Ash Borer is now present in Boulder, Colorado. The State Department of Agriculture and USDA/APHIS have issued an Ash Quarantine for all of Boulder County, which prohibits the movement of any Ash material out of the Quarantine Area.

Private Trees

Property owners are responsible for their trees and can contact a private licensed tree service for pruning or removing a storm damaged tree. Businesses that make tree pruning or removal cuts at 10 feet or greater above the ground when working within the City limits are required to be licensed by the City of Fort Collins. Licensed tree services have the skills needed to prune or remove a tree correctly.  Homeowners can prune their own trees. Tree work can be dangerous and if not done correctly can further damage a tree. Using a skilled professional to do tree work can help insure that a damaged tree has the best chance for recovery.


Branches from private trees can be chipped by a private tree service or hauled to Hageman Earth Cycle located on East Prospect.  Limbs can also be hauled to the Larimer County landfill.

Some Frequently Asked Questions

Is there a place to drop off tree limbs I've pruned from my tree?

The City does not accept tree limbs or any yard waste. However, there are some local business that do accept yard waste and tree limbs for recycling.

Where can I get free mulch?

There are two locations - 1: The City's Timberline Recycling Center (1903 S. Timberline Rd)); and 2: in the parking lot at the Gardens on Spring Creek (2145 Centre Ave). Mulch is placed in the bins each week, but at no specific time or day of week. If the bin(s) are empty, you'll have to check again on another day. People may take as much mulch as they need; not for commercial businesses.

I cut down my pine tree that had Mountain Pine Beetle, what do I do with the wood?

There are three options: 1) You can have a company come to your house and chip all the wood and then use the mulch yourself, or have that company haul it away. 2) You can take all the wood to the Larimer County Landfill to have it buried. You need to let them know it's infested wood, so please contact them at 970-498-5760 to find out what to do when you get to the landfill. 3) You can strip the bark from the wood, and then use the wood as you wish; but this is a tedious process and may not be worth the work. In addition, the bark would still have to be taken to the landfill.
