Knowing when the nectar/honey flow is going to occur is a great and wonderful thing. But there is an ENORMOUS " but" here, meaning, but, there can be times when things are not right. This is an example only. We have a massive flow in our area (as do many others too), that is called the blackberry flow. That is one of our main flows here. Generally, when the weather is "normal" that flow occurs pretty much at the same time each year. That be in the week of early June, generally, around the 5th of June. That flow lasts for a month.
Last year, our area, and many other areas experienced an incredibly cold and dark spring, with not much sunshine, and it was EXTREMELY cold. The blackberry flow did not commence until the first week in July. Now that is one month past the general time. That was very difficult on the bees. They built up in the spring as they normally would (mostly due to a lot of human intervention, like giving pollen patties). But then because of the lack of nectar/pollen from the blackberry flow, the bees ate most of what they had gathered from the alternate sources of food. This caused hardship, amongst other things in the areas. The bees did not have a chance to store/save an abundance of honey for the human consumption. In British Columbia there was an incredibly low amount of honey that was able to be used for us. There may be exceptions to this, where some may have had lots of honey, but none that I know of. Anyways, so flows are so different, and can occur long before or after the anticipated honeyflow dates. Just some thoughts here, have that wonderful and awesome day, life, attract great health. Cindi
