Mountain Horticulture and High Altitude Gardening

Volunteers at the entrance of the Native Plant Demo GardenMaintaining a garden in our Clear Creek communities presents its own unique challenges.  Our growing season is shorter than many other areas in Colorado, wildlife is abundant and elk, deer, and moose are known to wander to wander through our garden and vegetable beds. Many plants simply can’t survive the high elevation conditions. As your local office of CSU Extension we have numerous resources to answer your questions so you get the most out of your high altitude garden!

Extension Thursdays

Clear Creek CSU Extension’s Extension Thursdays series features a variety of activities and presentations, some of which include horticulture topics.  Find them on our calendar.
