Run, don't walk, to your nearest Home Depot, Lowe's, Walmart, or garden store and buy Slug Bait. (Sluggo, Slug be Gone, etc.,). A few holes in the leaves isn't the main problem, its when the slugs eat off the entire tip as the lily shoot is first emerging that's painful. No tip, no flowers this year, and stressful for the bulb.

First pull back mulch from your lilies, (especially leaf mulch which slugs like to hide under). Then sprinkle the slug bait to make a perimeter barrier around your lilies. Slugs will find your lilies before you even know they are coming up so also make barriers around any other lilies that haven't come up yet. Do shady/densely planted gardens first since slugs are more of a problem there.

Good luck, Helen

Got any rabbits? I have to battle them every year. I use Ropel that I buy at Lowe's. Good luck with whatever it is.
