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.

Sorry about what happened. Sadly that's the main reason it is better to stick with commercial products made and tested specifically for use on plants. I've heard of a few similar concoctions damaging plants. No, the damage cannot be reversed, once a leaf is damaged it will stay like that until it dies, but hopefully the plants will regrow new leaves eventually. The only other thing I can think of would be to cut the hostas back. I know they will regrow new leaves from late freeze damage here but whether they will at the stage of growth they are in your area I don't know. If you decide to try a "home-made" remedy another time it's a good idea to test it on a plant or two first to make sure there's no reaction.

...you're so correct...should have tested it first...I'm still kicking myself!

I hope cutting your plants back or trimming them will work and they aren't permanently hurt.

Hi & welcome! Don't kick too hard, all gardeners make mistakes. Each is a learning experience.

I don't use any 'cides, home-made or store-bought. If a plant can't make it here without those things, I can replace it with one that can. Usually mother nature provides a balance if things are left alone, beyond some manual adjustments like trimming off badly affected parts of plants, manually moving pests to other locations, smashing them. For every pest, there is a predator.

My most reliable form of slug control is to have a bird bath. Hungry birds like to bathe and take a drink, and many birds like to eat slugs while they're hanging around. ;)

Yikes ! That mix sounds like a weed killer.
If you haven't, take a hose sprayer and wash your plants off. It's better late than never !
For snails and slugs, sprinkle some dry oatmeal, or corn meal on ground. It kills them.👍👍
