Recently, I saw a suggestion/idea at "Hometalk.com" for a mixture of ammonia, Listerine, Epsom Salts, and Ajax Lemon Dish Soap to spray on Hostas to guard against pest (snails), etc. I made up a batch and sprayed it on about 20-25 various hostas around my garden/landscape, but much to my horror, about two days later I noticed some of them had brown damaged areas on their leaves, as well as some varieties had light yellow spots. Even more horrible was the fact that some of my other plants (like a once beautiful, thriving Lungwort plant), a Bleeding Heart, and a Tea Rose, which were next to some of the sprayed Hostas, must have gotten some of the spray on their leaves as well... and now they too have even worse damage (i.e., brown, crinkled leaves). I am devastated, and was wondering if there is anything I can do to reverse the damage, or revive them. I am also curious if anyone else has tried this mixture with success.
