Bumblebees are used for pollination in our high tunnels. The hives are mail-ordered and come in the form of a small cardboard box. Bumblebees don't mind working on cool, cloudy days and are very effective pollinators in high tunnels because they are not hindered by the effects of plastics on light quality. Floricane raspberries will be ripening in the next week or two.
