people keep saying put a slab of fondant on a hive but how much do people put on? Or is there a ratio that people use? ( so much fondant will get them x stores?)
I use old plastic butter containers. Two reasons.
when i open a slab of 12 kilos of fondant, its easier to quickly divide it all up and none goes off ( or i mean goes rock hard.)
300 grams ( approx per container, is portable and easy to apply on top of the feeder hole. If their desperate and light, i will roll it to the size of the bee space, very quickly, whip off the cover and lay it on top of the frames.
Its stored in a cool area, but if i think i will need a few, i bring them in , in their containers and let them warm overnight in the house.
You can cover over feed when its in place on the crown board, or directly on top of your frames. With insulated bag and/or wood shavings. This is better than polystyrene as it insulated all around the candy and you drape or wrap your bag of insulation all around the candy container. No heat loss from the fondant if they warm it up.
if you feel the tub and its warm, their most lightly working it. As its gets empty, you can squeeze the container and you find it bends really easy as they empty it out.
I say dont give too much, just set up your hive so you can assess the stores level, quickly and efficiently, with no stress to your bees.
putting huge slabs of cold fondant on top of your bees, is not ideal. Ok the method is perhaps more labour intensive, but it does mean you can monitor feed levels if their low and rectify it without any major intrusion, but i also add this is more important on Nucs and their reserves can be dominshed very quickly.
I lost a few nucs last spring through starvation, when i thought they had made it through winter, so learnt a lot. Candy is a good security, but dont over do it. If they have plenty and the hive was full in the autumn, they normally have more than enough until at least the end of February. sometimes you can add fondant and they just dont touch it!
