Since you gentlemen are talking about clover and bees, I thought I'd just add an observation I had today. I have been planting seven apple trees I got from Cummins Nursery. Because of my COPD it is an all day job to plant 4 trees one day and the other 3 plus 2 DCO's the next day. today I was really having a hard time. Heat and humidity together are almost unbearable for me. I was taking one of my many breaks and just sitting on the bucket of my tractor trying to relax. The clover in the area is booming. White flowers everywhere. I had been sittiing for maybe 20 minutes when it dawned on me that I had not seen a single pollinator of any kind. I purposely sat there for 30 more minutes jusst concentrating on seeing bees or something. NO GO. In about 45 minutes, I had not seen a single insect of any kind. I think this all began last spring when Duke Power had a contractor come along the ROW's and spray prior to doing some work on them later last summer. They did manage to overspray and kill all my chestnuts and most of my Burr Oaks. NOw I think that whatever they used killed off all the local bees also.
