How long before a new beehive begins to forage?
Actually, the beehive stays in one place. I’d love to see a Langstroth flitting among the flowers, but so far no luck. The bees themselves, however, start to forage almost immediately after they are installed in the hive. If it is warm and dry enough to fly, some bees will begin orienting themselves by flying in ever-widening circles around the hive. In no time, they will be out foraging for both pollen and nectar. If the weather is bad, you will see them out in the first decent weather that follows.
