Thanks for your interest in CSU Extension's Green School training! This is a unique opportunity to learn from CSU horticulture experts about gardening and growing in Colorado. Registration is currently closed, but sign-up below to learn about our next training which will begin in Fall of 2025. We'll email you first when registration opens for an early-bird discount in August 2025.

While you wait, read information about this educational option and check out our short courses open year-round. Note that the Certified Colorado Gardener training is NOT the Colorado Master Gardener program which requires volunteer service.

What do we do with your information? We keep this list ONLY for Green School. We do not share your data beyond this use. You can expect about three emails next fall and that's it!
Are you employed in the Green Industry? (Landscaping, nursery, design, etc.)
Are you a Colorado State University employee or a County/City employee in Colorado? You may be eligible for a discount.
