Students from last year's course say . . .

“The course was amazing in so many ways. . . . I always felt so nourished after our workshops. . . . I love the practical but I also love the theory and philosophy that goes into all of it. I am now more in touch with myself as a teacher of children because of this course.”

— A teacher from Pennsylvania

“I loved seeing the progression of the garden through the year, learning to use cover crops on vegetable beds, and thinking about the whole year's plan. I was inspired by the ideas about how to integrate animals with the garden and seeing the farm as an organism. I thought it was so important that Mac stressed the importance of respecting and learning from local farmers, whatever their approach.”

— A teacher from New York, NY

Seed School at the Pfeiffer Center, Part 3

Thresh and Winnow:
Harvesting, Cleaning, and
Storing Seeds

With Shanyn Siegel
Saturday, October 22, 9:00am-5:00pm

Did you know that clean, properly stored seeds can remain viable for decades?

In the last installment of Seed School at the Pfeiffer Center, Shanyn Siegel explains and demonstrates various techniques for harvesting, drying, and cleaning seeds — all using tools and materials found in any household. Class discussions will focus on the different types of seeds and how to best gauge seed maturity • simple, small-scale harvest techniques • understanding seed quality • and the best options for storing seeds at home. Hands-on activities include wet and dry seed processing, germination testing, and more.

Come just to learn — or bring your own seeds to clean and share! Participants will leave with some seeds grown in the instructor’s home garden — and with ties to a growing network of regional seed savers.

Gardening starts with seeds. Why not save your own?

Shanyn Siegel has worked in sustainable agriculture and horticulture for over 15 years, specializing in organic vegetable gardening and organic seed production. As Collection Curator and Head of Preservation for Seed Savers Exchange, Shanyn grew, evaluated, and saved seeds from thousands of heirloom and open-pollinated vegetable varieties. With Lee Buttala, Shanyn coedited The Seed Garden: The Art and Practice of Seed Saving (2015).

Presented in partnership with Seed Savers Exchange and Hudson Valley Seed Library.

Beekeeping for the Future

With Bill Day
Saturday, November 12, 9:00am-5:00pm

If you are thinking about getting honeybees next spring, now is the time to prepare. This one-day workshop will address questions all aspiring beekeepers need to ask as they prepare to embark on this spiritual yet profoundly nature-bound journey. For beekeepers with one or two years’ experience, this workshop is a great opportunity to take stock, ask questions, and learn new perspectives.

The workshop will be organized around the beekeeper’s essential role in nurturing the hive organism. What can we as beekeepers do to create conditions in which our bees can thrive? What are the most up-to-date natural and holistic methods, and how do they work?

Topics covered will include: the biology of the hive organism and the beekeeper’s role in fostering healthy hives • working with different hive designs • sources of bees • siting your hives • biodynamic methods for disease management • beekeeping as a path to heightened powers of observation and awareness • and much more.

Weather permitting, the day will include a visit to the Pfeiffer Center’s apiary, where we will open some hives and demonstrate techniques discussed in the classroom.

Bill Day has kept bees for more than a dozen years. He is principal beekeeper at the Pfeiffer Center, and also keeps bees at Bluefield Farm in Blauvelt, NY.
