I'm going to try the ammonia/water next spring. I have a terrible problem this year with slugs. At least I think it's slugs. Loads of very tiny holes in the hosta leaves.
A couple quick questions:
Should I be cutting the hosta leaves back later in the fall?
Do you think it would be a good idea to rake the old mulch and replace it with new? What's there now simply built up stuff that has dropped off of the gigantic cedar tree that they are planted under. I figured it would be good mulch as it seems to be something that the slugs would not like to crawl around in.
This picture is from two years ago when there didn't seem to be a problem, but you can get an idea of what is there for mulch.
