Is there any season for bee to migrate, to new place or environment?
Spring. This is the time bees swarm, but bees could be on the move anytime during summer and autumn too. Depends on the species of bees and the conditions. Have you found someone in your area to teach you how to look after bees? It is not simple and without much knowledge your bees may die.
I have not lean about it from anyone but only True online video, I started my farm last year to back myself up financially in my Educational level.
