Re: Buckwheat honey
I've grown buckwheat for my bees for the last five years. From those five seasons I've had 3 good crops of buckwheat honey, 1 so-so crop of buckwheat honey and 1 year I had no buckwheat honey at all. It's not that the bees didn't harvest the nectar during that year, it's just that the buckwheat was the only flowers that the bees were able to get anything out of and therefore they used it all up before I could get any myself.
I always specify "Mancan" buckwheat when I buy seed as this is the "common" variety and has always produced nectar for my bees. It normally takes about 3 weeks for the plants to grow to their flowering stage which normally lasts for 5 to 6 weeks. I've never tried "Manor" variety and can't comment on whether or not it will produce nectar for your bees.
Buckwheat honey is very strong and some people just don't like it but I have enough customers that absolutely love it that they anticipate my harvesting it and are normally waiting in line to buy it. I've never had any left over after a month or so.
