so he's adding apistan even though there is no mention of mites and there is nectar coming in? i've got a similar background, kept bees in the 70's and 80's, started back in the 90's, stopped around 04 or 05 then got back in in 2011. he's right, it's a bit more complicated but i don't like seeing mite treatment when nectar is coming in. i didn't look to see his location, but march is too close to the flow to start treating down here.
