Have you ever considered a Master Gardener Program? I myself, would love to! The only thing holding me back is the mid week schedule and the fee. But maybe, you are in the position to consider it. This is a great local and comprehensive program put on by the Colorado State University Cooperative Extension office. It is a 60 hour program that covers everything from plant and tree disorders to pruning and where, what and how to grow. CMG certified individuals can get continuing education by volunteering in the community and attending additional training. If your interested in our local program visit the Colorado State University website.
So if you are looking for a solid background in local garden information, give it a try.
Don't delay, most Master Gardener Programs start in January!
