I too, admire anyone that can garden organically. I tried but the aphids were winning so I had to go for a bigger gun. I'm very careful to follow instructions and don't use too much. It's something that I learned in my master gardener course years ago. They had a chemical saleperson give a talk and he stressed over and over to never use more than the directions called for. He said it wastes money and can be very dangerous to your plants, animals and self. So, this is definetly one of those times that less is better!!!
Be safe and have fun, Mona
