I currently have 26 here at home, thats about six too many.. 40 acres here I dont like to go over the 20 mark in one spot.. I have hives at my fathers place, up on a hill away from his house, about 300 acres there.. I have hives about 2 miles from his house, which is about two miles from my house.. The farmer at that location had a hive of his own and asked if I would go through it for him... He put it there last spring in a single deep, then never went back after getting stung.. That was quite a mess to get fixed, but has yielded a good spot for a few extra hives.. I have hives on another farmers land that I often help during harvest a few miles north of my fathers place, and I have hives in another spot about 35 miles away. Only a couple there, not sure how long they will stay that far away.
Acquaintances, friends, and people I have met removing bees. Like most, I have been offered locations to keep hives. Unless I know the person well, I usually don't put hives on their land. Going to pull supers and finding wild comb in an empty super really makes you re think those offers.
This year I could run 30 to 40 hives per yard. We have had ample rain and everything is in bloom.. Last year Ten hives per yard would have been too many by the first of July. We didnt get rain from the middle of June to the middle of September. The September rain and Goldenrod was all that allowed the bees to be prepared for winter.
About the time fall arrives there will be a major reshuffling of hives to the outyards to take the most advantage of the goldenrod and other late plants. Having three or four locations.. even temporary ones are a great benefit. Permanent ones that are not a long ways away are a serious bonus..
