The recent release of the Gardens’ book “Wildflowers of the Rocky Mountains,” authored by the experts of our own Horticulture Department, has renewed interest in knowing and growing our best native plants. On the third Wednesday of every month (April – October) wander with one of these authors through our acres of naturalistic gardens to see which wildflowers are at their peak. Since many bloom at Denver’s elevation before they bloom in the mountains, seeing them here first can help you learn what to look for, where and when.

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.


Price: $44, $39 members

Instructor: Patti O'Neal


Special Instructions: This class is a lecture and hands on lab. You may bring a sample of a plant or turf you want diagnosed to class. Registration confirmation includes info on how to collect a good sample.
