The trees, specifically the maples all bloomed in March, then it froze, and the buds fell from the trees... Two days ago it was 70 degrees, and there were new blooms... today we are in the grip of an April snowstorm. It sometimes makes me wonder how trees OR bees survive such crazy weather. As beekeepers, all we can really do is wait. make sure the hives you have that are out of resources have sugar cakes, winter patties etc on them, and keep our fingers crossed!
Have patience, spring will arrive eventually!
