I have used bayer Rose Food since in was $2.99 a blue bottle. That's a long time. Now I have read that it has a pesticide that kills bees. I have to admit that I used to wonder why bees were walking in circles on my patio. I wrote them and got the answer that no one is sure about the deleterious effects of their pesticide. I'd like to know of a fertilizer that might work as well and not kill bees. Any thoughts would be welcome.
