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.
