How do you know when it is safe to start grafting queens in a given area.
what are the signs or signals that say it's time to start grafting?
Is it when the day and night time temperatures reach a certain mark?
Is it when you see pollen coming in? Is it when the hive you want to graft from has X number of frames full of sealed brood....
I know there has to be drones flying by the time the queen is ready for here mating flights.
I'm having a really hard time finding out when people in my area generally start grafting to produce queens for splits.
I'm just north of Toronto in Ontario Canada.
there is so much info on why and how to graft queens but not when to start specifically. I don't want to start too early or to late.
