Im actually getting a less than expected average over my 300 production hives (now around 400). 80lbs average, well below our long term average of 100lbs (northamptonshire - > worcestershire).
40lbs spring, 40 lbs summer. I think it was the dry spell that brought the flowers on early and they crashed and burnt out by the end of june. Basically have bought no surplus in for the last 6 weeks. Some sites pretty good, some pretty poor. I believe access to clover was crucial.
We brought a few to wales for the heather, but it was a half assed effort.
I havent really seen a huge stand of Balsam around by us. Shame really because it seems its a good yielder.
I thought at one point we were in for a huge crop this year. Alas it wasnt to be.
