Adding new foundation

[jsharum]

How do I know when to add supers of undrawn foundation to a hive coming out of winter? Thanks

Two things: They need to be getting crowded in the hive.
You need to have a nectar flow.

When I see dandelions beginning to bloom, it's time for supers.

When what you have is 70 to 80 percent full, you need to add more.

i guess i should be more specific. I am running a deep and medium as a brood chamber and upon an inspoection last week the deep was open for the queen to lay in and most of the medium still had honey in it(or 2:1 syrup). So I just want to leave that medium on and put supers on top and hope they consume most of that before the flow?

Sounds to me like they are a ways off from needing supers, you would want them to use up the food in the medium for producing brood in the lower deep first, then the queen will be able to move up into the medium. I think your bee/brood population needs to be a bit larger before adding any supers. John
