I 've been at it about 6 years or so now and I'm seeing a trend when it comes to my honey production . In good years like 2019 we had more honey than thought possible rain was plentiful but not to much then in 2020 we had a hard dearth and didnt take one drop of honey off the hives so good year 400 pds and bad year zero thats with 7 hives give or take . I know planting for forage has been talked about alot but i havent seen any suggestions for Pa. zone 6a . My fields are goldenrod now and thats good for the fall flow but thinking about a good summer forage to help them through the dearth . I 'm having a hard time finding a good plant that can take dry summers and not invasive , the ones that keep popping up are Borage , Joe pye weed ( might be invasive ) mint and Autumn Joy Sedum . Are any of these a good hardy plant that could add to the summer flow .
