To get its first beehive, the young beekeeper can pick a swarm in a tree in the spring. It remains random and harvesting a swarm is not easy the first time.

You can simply buy a nucs from a professional beekeeper.

To create a split, commercial beekeeper divides one of his hives. He takes 2 frames of brood and places them in a nucs.
Then, he introduces a young mated queen whose race, genetics, gentle and ability to collect honey, he knows.
After a few weeks, split is ready to be delivered to your garden.
