Making Great Compost: Hot, Cold and More

While our ancestors realized that compost was helpful for growing plants and improving soil health, they did not know how or why it works. They inherently knew that the single best thing you can do for your soil is to create your own plant based compost. This class will teach you the science of composting based on 50 years of research – relatively recent compared to the 2000 plus years that humans have been composting.

Come learn about the various microorganisms that do the bulk of the work making good compost, the materials and proportions you need to make it the best possible, and the three main ways to create great compost; cold compost, hot compost and vermicompost.

What Made My Good Plant Go Bad?

Rocky Mountain Gardening Elective

Did the glorious beauty promised by the garden catalog, nursery salesperson or garden designer fall flat? You may be surprised that insects and diseases are NOT the main cause of problems in the garden. Gardeners have more control than they may think over many plant problems. As much as we do not like to think it, humans cause most of the issues in the garden; many of which result in an insect or disease problem as a secondary issue   NOT the first.  This provides an overview of the most common plant challenges and what you can do to prevent their annual recurrence. The course focuses on the root causes that eventually attracts pests and disease to your garden and what to do about it.
