I usually try to pop in a pollen patty aound mid March, quickly lifting up the inner covers, sliding them in and closing things up. This year however, I have a bunch of frames covered in pollen that are not moldy or anything, sitting in my basement. Would the bees be better off with these frames if it warms up enough for me to remove and replace a frame or two, or would the patties be right where they need them with a lot less disruption? How easy is it for the bees to use the pollen in the frames after it has sat for any length of time? Would I be better off saving these frames for nucs or splits?
