Re: FLOW? What exactly is it and how do I know it's time?
I think when the flow is on is a particularly hard question for the urban beekeeper to answer. We in the urban environment do not have masses of native plants nor do we have fields of crops for our bees to forage on. However, local gardens and landscapes do provide forage. If you live in an urban area look around and see what is blooming that the bees are working. As an example, I find in my own neighborhood that rosemary is often used as a landscape element, and the bee work it intensely when it is bloom. They also work many kinds of trees, for my area avocado, citrus, eucalyptus and pepper trees all are good sources when in bloom. The calendars mentioned will also help you figure it out.
