Sean Kelly. To tell you the truth, I am not sure what are the flows. I am thinking that blackberry is the last of the main flows. But then, there are so many minor flows that I am aware of, they go on and on.
I think one of the next important flows are the pumpkins in our area. I cannot give you any direct answer to this Sean. At my farm, I have a flow that continues on until frost kill, but then that is because of the myriad of annuals, perennials and wildflowers that I have growing that feed the bees, it goes on for a long time.
I think that I remember somewhere on the forum that there was a site that one can go to to find out about the flows, but I honestly cannot even recall the exact time of the post, nor do I think that I could find it. I will sometime over the next few days see if I can figure this out a little more better for you. It would be good to know.
I would be curious about what kind of country side you live in. Are you in the city, country, specify.
When we had a queen breeder come to speak at our bee club meeting, he indicated that he kept bees in the outskirts of the City of Vancouver, in New Westminster, and he gets way more honey from all the gardens in the city than the people in the country. He was very adamant about this and really believed it. I must believe it too. Anyways, I will try to work on this for you too, you do your work too and maybe we can figure things out together. Have a wonderful day, great life, love this life we're livin'. Cindi
