But are you spraying Bayer, or something else? I don't think soap is going to knock these down. I think maybe the intense dry heat (105 today in Westlake) may have a part in it too.
One thing I haven't done in a while is use the "recipe." I ran out and didn't make a new batch, instead using Miracle Gro and other fertilizers that I had. I think I'm going back to the recipe, or at least add it in, and see if it makes a difference.
No need to worry about poison in the garden. There's nothing in our garden that we can eat.....I am not a very successful farmer....either!
