Countryboy, you said it better than i could, i've been truck gardening for thirty years, (thats not growing trucks from seed :-D) i have twenty hives here at home within a few feet of my 3 acres of sweet corn. When it tossels the bees are all over it ,but don't ever remember seeing bees on the silks :? like countryboy said if they were it's for water on the silks or leaves. ( dew in the mourning or after a shower) As for borage, i plant it and catnip in outside rows where i plant cucumbers,this gives them something else to work that produce nectar, bees get very little from cucmbers and would starve if that was all they had to work.You can come up with all the number of plants and how many acres you plant, and say how much honey you will get. But the weather is the main factor that will determine that. Jack
