These are the Hazel flowers on Nov 16th, they are still not open yet but this years leaves haven't even all fallen yet. A couple of dry warm days like today and they will break open. A couple of frosts and they will go brown and die. Either way the bees are unlikely to gather much pollen from them. Hazel appears to be advancing by about a week a year since I started keeping bees in 2012. The Alder is looking the same too. Its another reason why pollen subs is so important to a successful season for me.
Despite the torrential rain over the last 3 days the Hazel has burst into flower, the bees are gulping fondant down taking a Kilo/week at the moment. This is danger time. Its too warm so the bees are brooding but its 40mph winds and rain so they can't fly to gather pollen from the Hazel that will be gone in a couple of weeks. I will have to feed pollen subs soon then the big danger will be the snow end of February or in March that will come. The seasons are finished, you just have to make it up as you go.
