In my strongest hive the bottom deep is full of pollen. I was thinking about taking it away and giving back for winter or in the spring. But how can I store the frames with pollen.
same as empty or honey frames
If you want to store frames of pollen, your best route to take would probably be to freeze it. Just toss it in your freezer, maybe in a bag or tupperware container. The biggest threat to pollen storage is mostly mold, so just keep it cold, and it should keep just fine until you need it.
Thank you for the responses. Yes, I think frozen should be good even to the next spring.
Either leave it on the hive or leave it in the freezer. They will need that pollen next spring.
When it dries out, is it useless to the bees?
Drying the pollen won't necissarily make it "useless" but, it can cause a greater degradation of the nutritional quality of the pollen. Put simply, freezing it just keeps it better and makes the bees more willing to use it come spring.
