Thin Your Forest to Keep it Healthy

This allows your trees to grow stronger because they don’t have to compete as much for resources.

To develop a forest management plan for your property, contact the Colorado State Forest Service - Golden District, 303-279-9757. You can also contact a professional forester.

Treat High-Value Trees to Prevent Infestation

Using Carbaryl (Sevin) or permethrin (Astro)-based pesticides on a yearly basis can help prevent infestation of individual trees (May 1 through July 15).

Always read and follow label directions. If you prefer not to do the work yourself, contact a licensed pest-control professional.
