why dont you be the first to find out!!!! ..... lol

no clue ...

Most don't use my method which is a hose end sprayer filled with full strength ammonia and let the sprayer mix the solution. IÂve never bothered with the mixing and never had a problem.
I suggest that you drench the ground under and around the plant not on the plant itself. They will not be on the plant unless you do it at night; they are hiding from the sun.

Probably not- in some hosta articles I've seen 4 parts water to 1 part ammonia is recommended. Ammonia is part of many (most?)
fertilizers and contains Nitrogen and hydrogen. A 10:1 ratio is really pretty mild. I intend to use a slightly stronger mix. I want slugs dead.

Let us know how it works out, Sassy! :o)

IMHO a pressure sprayer is much more effective since the spray nozzle operates in such a way to penetrate the entire hosta...on top and under the leaves and all around the base...with a minimum amount of solution.

Papou, a lot of work!

Well, I did it. At least on the 103 plants that I have planted at my camper.
The largest container that I had there was a 5 gal bucket.

I filled it up with water and put in 1/2 gal of ammonia.
(Between me and my RV neighbors we decided that was a 10:1 ratio. lol)

I then used a sprinking can (you know, those things with a handle and a bunch of holes on the spout)

I pulled the leaves back and I totally saturated the whole crown plus the ground around the plant.

Sure hope I didn't kill my poor hosta.

If ammonia/water at 10:1 ratio kills slug eggs then I know their dead. I just hope that's the only thing that will be dead. lol

I think I'll wait and see if there's any adverse side effects before I do it to my hostas at home.

I'll keep you all informed of my experiment.

Thanks for all your input.

OK, yesterday it had been 5 days since I POURED the ammonia solution on the hostas at my camper. They still look good!

I don't know if 5 days is long enough to see if I had damaged them or not, but they look pretty much like they did last Monday when I did the experiment.

The hosta at my camper are closer to Lake Erie and are still protected by the temp of the water. Everything up there looks better then they do down here in Ashland County where the temps are lower right now.

Anyway, so far so good. Maybe the true test will be next spring. Will they come up? Will they be stunted? Will there be less slugs?

As the saying goes, "Time will tell"

Maggiemae, lol....yes it's true..its a lot of work.
On the other hand it gives me a chance to ADMIRE each hosta variety in my collection....
....not at this time of the year however...lol...

I bet your hosta will be just fine, Sassy! Next Spring, I'd repeat the process, just for good measure!!

"Happy Camping", cause the "Happy Hosta Season" can't last much longer in Ohio!! So far, everything,
for the most part, still looks great for me--but, I know it's coming--that "last hosta day"--and, not too far
off I fear!!!
