How Are My Bees?
Understanding and Meeting
Your Bees’ Midsummer Needs

With Bill Day
Saturday, July 28, 9:00am-5:00pm

The height of summer can be a challenging time of year for the bees. Many locales experience a dearth of forage, the varroa mite is flourishing, and many hives are rebuilding after swarming or natural queen succession. Meantime, winter is approaching — faster than you think.

This workshop will focus on midsummer tasks every beekeeper should have in mind to ensure healthy hives and successful overwintering. Topics covered will include: Assessing hive health; when to super, and when to take off boxes; harvesting honey; assessing honey stores, and knowing when and how to feed; monitoring and managing varroa; management options for weak hives; and more. There will be ample time for questions and discussion.

Weather permitting, much of the day will be spent outside in the Pfeiffer Center’s apiary, where techniques discussed in the classroom will be demonstrated.

Bill Day first learned beekeeping from Gunther Hauk as an intern at the Pfeiffer Center in 2001-02. He is the Pfeiffer Center’s beekeeper and beekeeping instructor. He also keeps bees at Bluefield Farm in Blauvelt, NY.

Introduction to Biodynamics

with Mac Mead
Coming in Summer 2018

What is biodynamics? There is so much to discover about this modern organic way of agriculture and land care, which works not merely to maintain, but to raise the vitality of the soil and its produce. Biodynamics combines novel techniques of building up healthy soil with a renewed awareness of all the forces at work in the farm organism: among and between the soil, plants, animals, and humans, as well as the cosmos itself. In this introductory workshop, veteran biodynamic farmer and educator Mac Mead will introduce the reasoning behind the methods of biodynamics.

Location: Brooklyn Grange Rooftop Farms, Clinton & Flushing Avenues, Brooklyn, NY 11205.
