I made something out of dawn and water That I used on an ornamental
Basically 1-2 TBS per qt.. I usually use castile vegetalbe soap in the Veg Garden but I use Dawn original on my Prickly Pears because those cored bugs are tough buggers. Dawn is a miracle but not quite organic. Some people will mix in some cayenne , orange oil or other stuff. But this is a good base. Google it and look around.

Here is a link that might be useful: Recipe for INsecticidal soap
