Just pips peeking thru, only pineapple upside down cake is all unfurled. Do I have to keep the solution off the pips? Leaves? Do I spray day or night? is it 20-1 ratio? I've cleaned up my beds now and want to really keep ahead of the slugs this year. How often do I do this? once, weekly? Oh, should I do this in my daylily beds to keep them from migrating over to the hostas?

Viola Ann, I know you do this advance spraying to kill the eggs. Today is the day!! Thanks for your help all.

Try 1 part ammonia to 10 parts water and just dump it on the clump, preferably BEFORE the leaves unfurl. If they've already unfurled, dump it at the base of the clump. Early in the season will get rid of eggs as well as slugs and greatly reduce the number. Good idea to do it elsewhere if you have other spots that slugs congregate. I usually do that just once a year, but sometimes repeat later in the season.

Thank you sooo much, Viola Ann. Iespecially like that dumping part instead of trying to go spray carefully. I wonder will it hurt daylily leaves?

I doubt it will hurt the daylily foliage. My hosta are still all sleeping pretty deeply but that hasn't stopped me from poking around and sure enough I HAVE found some baby slugs nestled right around the old scapes from last year. I'm going to try to do the drench this year too.

I should have said above that later in the season I sometimes use the 1:20 ratio. I think it will still do the job and it's less likely to burn if it does get on the foliage.

Don't count on it! But it should help.
