I am loathe to say this in case I am courting damage - but our hostas which last year were plagued by slugs are this year doing really well. I have put small shingle round the roots (they are in pots, as they were last year when they suffered badly). No doubt the slugs will now return, but so far so good, so perhaps shingle around the roots works? A long time ago there was a liquid de-slugger (if you like), which worked absolute wonders over-night. I used it for a couple of years, then quite suddenly it was no longer available, probably because it contained some substance which was a health and safety risk!
