Has anyone had experience in feeding bees outside the hive to encourage them to fly to all parts of orchard and pollinate trees.
external feeding is a cheap nasty way of feeding. i know guys who have done it. theres usually a ton of dead bees left behind.
in an orchard situation you will attract bees from neighboring orchards and it will turn into a robbing frenzy. they then can go beat up any hives near by, which is probably yours and rob out anything thats weak.
also if they get wound up they can end up stinging the crap out of any orchard workers/owners that come near.
as mentioned above, bees will do the job just fine without any help. the causes of poor pollination are typically out side of your control ie weather.
