We have been hot, hot, hot and dry, dry, dry here in Oklahoma for most of July and so far in August. I haven't done anything for the girls as 1) they laid up plenty of honey and pollen in May and June -most of which I have left on all 3 hives of my hives, and 2) I live on a small urban lake so they have plenty of water less than 50 ft. from their front door.
Last year the honey crop was dismal as the heat set in much earlier so I had to feed, feed, feed just to keep them going.
