I discovered big field about 2 miles away. Looks like it is to close to move but is it close enough to have good nectar flow from it?
I suppose that bees do not fly 3 km = 2 miles. And if they fly they lose 2/3 of yief during flying.
I suppose too, than cranberry is not a good honeyplant. If you take there one hive, it is able forage all honey from flowers.
After my experience when bees forage over 1 km or 1 mile, half of yield will vanish for distance.
