Sustainable Greenhouse Design

Rocky Mountain Gardening Elective

Have you ever wondered if a greenhouse that needs NO supplemental heating or cooling could be made? The answer is yes!

No more over-heating and freezing in all-glazed greenhouses. The sustainable design balances the use of thermal mass, glazing, insulation and sun angles to achieve the stabilization needed in our extreme climate without the use of fossil fuels. Learn how to design a sustainable greenhouse from the ground up, using salvaged or new materials to achieve the look and performance you want. You can also use these techniques to improve an existing greenhouse.

This class is a comprehensive look at how passive solar greenhouses work and covers topics such as how to orient the building, basic principles of passive solar design including the use of stored water as thermal mass, simple math formulas to help guide your design, a materials list and drawings and calculations for a 13’ x 15’ greenhouse.

In 2000, the Parmenters built their first greenhouse out of 90% recycled materials on top of an 8,120 ft. elevation decomposed granite mountain. Since then, they have designed and built many more and are ready to share what they have learned about state-of-the-art materials and cost-saving strategies. Lose yourself in a year round garden sanctuary.

 

Price: $160, $150 members

Instructors: Penn and Cord Parmenter are high altitude food growers. They live in the Wet Mountains in South Central Colorado and they apply a multitude of techniques to overcome the challenges of the high country. Their totally sustainable greenhouse provides food year round for them and their three boys.

 

Tour - Wildflower Wednesday at York Street

 

Sometimes we need a quiet stroll among the wildflowers—without hours of driving and hiking! Denver Botanic Gardens has hundreds of native wildflowers right here onsite to enjoy. 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.
