I was informed today by the farmer who owns the land my hives are on that he will be planting tobacco this year in the fields around my hives. The closest field will be maybe 30 yards away. Should I move my bees away from that area? I know they spray tobacco for worms numerous times throughout the year. Also I have 18 hives what is the best way to move them? The nector flow will be on in a few weeks so I worry about hurting my honey crop.
