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!

Can you create a greenhouse that needs no supplemental heating or cooling year-round? The answer is yes!

This class takes a comprehensive look at how passive solar greenhouses work, 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 you with your design, a materials list and drawings and calculations for a 13 X15  greenhouse.
