What our students 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

Registration for this year's course has been extended to the second class meeting on October 14.

Beekeeping for the Future

With Bill Day
Saturday, November 11, 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 managing varroa and other health issues • 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.

With Mac Mead, Megan Durney, Harald Hoven,
& others

January 12-15, 2018

The Pfeiffer Center's 2018 midwinter intensive study of biodynamics offers participants an in-depth examination of two plants used in making biodynamic preparations: white oak and chamomile.
