Conifers for Colorado Landscapes & Gardens

Rocky Mountain Gardening Required Course Group II

Urban tree diversity is becoming ever more critical in our local and regional landscapes which have relied on a limited tree palette.

How do you choose from the wide array offered at local nurseries? This class introduces you to the diverse world of hardy conifers and reveals the secrets to their success in our local climate. From native species to exotic cultivars, we’ll discuss practical, cultural and design considerations. A morning classroom session will be followed by a walking tour and hands-on introduction to the Gardens' conifer collections. We’ll take a half hour break for lunch on your own (bring your own or eat at the Gardens’ café). Please come dressed for the weather. Landscape and nursery professionals are especially invited.

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.

Starting Your Garden from Seed

Rocky Mountain Gardening Elective

Few things excite a gardener more than buying new plants for their gardens, especially if the plants are exotics, unusual or heirlooms. Second-only to the creation of new plants is the financial benefit of growing your own plants, whether flowers, herbs or vegetables.

This class will demystify the seed-starting process primarily focused to the novice gardener, but a good review of the best success tips if a more advanced gardener needs a refresher. Learn simple seed botany and the process of best practices for successful seed germination, successful transplanting, and seed collection and storage and cover some of the reasons seeds and seedlings fail.

After discussion, participants will get a hands-on demonstration and students will leave with seed trays and seeds to return home and practice what you have learned in class. This class will help you up your game to produce all the transplants you could possibly need and set you up for upcoming classes on spring and summer vegetable gardening and succession planting.

 

Instructor: Patti O'Neal

Price: $37, $32 members, includes $5 for materials.

Special Instructions: Each participant will get a seed tray for seed starting, with all necessary materials to get your garden going this year!
