it kills on contact .... nothing left once it dries ....

job done.. relax

why didnt you just mix it in the garden with the garden hose?

if you had a one gallon watering can.. which is 16 cups... i would have just filled it.. taken out about 1.5 cups of water.. filled it up with vinegar.. stirred it.. and sprinkled it ...

any mathamagicians out there.. does that put me around 10%????

lets see one gal.. what.. 128 oz?... so remove 12.. add 12???

whatever... lol ...133?? since when ... its not even divisible by an 8 oz cup ...

im questioning my entire education.... and so confused ... lol

You're right Ken. If you take out a cup and a half, it will be 12 ounces. 10% of 128 ounces is actually almost 13 ounces, but it's close enough for government work.

I did not think to douse and spray———wanted to make sure I got that 9/1 ratio.......lol

So I put two cups vinegar in a gallon watering can then filled it with water. I figured close enough or even better if it’s over a bit. Then went to pour. It broke my back carrying those gallons....... so thank God I don’t have to do it again!!!

But the ground was damp yesterday not soaking, but damp, then it rained all day today......

oh no, I am getting worked up again......maybe it didn’t dry?? Arrrrrggggg!!

Maybe it didn't dry before it rained, but as Ken said "it kills on contact" so no more worrying!

Both vinegar and ammonia will kill slugs and insects on contact. Each will kill weeds and other foliage. People that use ammonia use higher concentrations for slug control. I have not found any information on which concentration is safer for foliage so who knows, from all I can gather I don't know if there is a difference. Ammonia will break down into nitrogen in the soil. Nitrogen promotes plant growth. It is also essential for photosynthesis,

The only difference is that ammonia breaks down quickly in soil producing nitrogen and vinegar does not. Walmart sells ammonia @ $1.16 for a half gallon. For this reason I use an ammonia solution rather than vinegar. Each to their own. -Jon

Jon----and how do you know it doesn't????? What mishap did you learn this piece of knowledge from?? lololo

I've done some careless things, but this was just a joke.....honest.

Should I douse my hostas, now all potted in fabric grow pots, with a 10% vinegar solution before I move them to Maryland, to my balcony, so I don't import slugs/eggs?

have you had a slug problem this year? I would recommend then----I got hit bad. I don't imagine it can hurt! I say go for it!

Thanks Djacobz. Tonight it's raining cats and dogs, started about 8 p.m. Supposed to pour all day tomorrow. I guess not a good day to douse. I have an extra bottle of vinegar I want to get rid of before I move, so making up a 10% vinegar solution seems a good way to use it. My friend Chris came over to help me transplant the last of my ceramic-potted hostas and heuchies to fabric grow pots. We got all done except for the largest ceramic pot with 4 mini hostas in it. I'll get that done tomorrow if it stops raining.

I think I better do this myself in the next few days. I think I have more of an insect problem vs. slugs. I have been controlling the slugs with slug bait. But with all the rain we've had, I could see populations increasing. I didn't know this worked for insects as well.

Is there any difference between ammonia and vinegar re: effectiveness? Any particular kind of ammonia? There is cloudy vs. clear.

Do I have to worry about it damaging other plants?

Can someone point me to a tutorial about the most effective way to spray/douse? I'd probably have to use a watering can like the OP. I have sprayers but the biggest is perhaps a quart in size.

Household ammonia is an aqueous nitrogen-based solution. It consists of five to 10 percent ammonium hydroxide (NH3) in water, often with added detergents. I would read the label and it should show the concentration. I believe 5% is the most common. If you find 10% then just cut the amount in half. Straight out of the bottle both ammonia and vinegar (5% acetic acid) will kill foliage. I use a 1/3 concentration of ammonia and don't have any problem with it harming foliage. It is overkill for killing slugs, but I look at the mild fertilizing benefit as better with the higher concentration (5% concentration Ammonia). I have a half gallon sprayer and it goes pretty far. The most important thing to do in spraying is to spray around the base of the hosta and all around on the ground under the leaves, any piles of leaves, mulch, any place they hide during the day.
