A fellow beekeeper gave me a photocopy of The North American Biodynamic Sowing and Planting Calendar 2012 by Maria and Matthias Thun. Much like the Farmer's Almanac, it also includes dates for working your bees. I was wondering if anyone else is familiar with this concept. The days are categorized into the following areas of Root, Flower, Leaf, Fruit, and Water. My friend copied the February 2013 calendar for me. A quote from the material given to me: "Earth-Root days can be selected for opening the hive if the bees need to do more building. Light-Flower days encourage brood activity and colony development. Warmth-Fruit days stimulate the collection of nectar. Water-Leaf days are unsuitable for working in the hive or for the removal and processing of honey." As I understand it 2/18/13 is a root day. Hives worked on that day will build comb. 2/22 and 2/23 are flower and leaf days. The hives worked on those days will produce honey. 2/25 and 2/26 are warm fruit days and the bees worked that day will collect nectar. 2/27 and 2/28 are earth root days which should stimulate comb building. Disclaimer: I don't know much about this and I could be wrong about what I telling you! I just wondered if anyone else was familiar with this couple's work.
