Seeing how my girls prefer my hostas to weeds, I am wondering if there are any spot spray weed killers that would be safe to use, particularly if they change their minds. Also- I normally spray my apple tree weekly for bugs/fungal diseases. I use red spheres to curtail coddling moth and maggot moths, but may need additional control to get good apples. The spheres are coated in non-toxic tanglefoot goo which attracts the flies and makes them stick to them. Any help welcomed!
