The slugs (or snails as I more often see in my garden) like my Violetta Pac Choi as much as I do, it seems.
An old spaghetti sauce lid full of an IPA some one left at our house. Stouts, wheats, and other Other Half Approved Brews don’t make it to the garden. Thankfully our friends are a diverse crowd and I usually have a misfit beer on hand.
If you’re without unwanted beer, I’ve also had luck with rings of rock salt (sold less expensively at our grocery store when labeled “ice cream salt.”)
Of course, if you’re less squeamish than I, there’s always the seek and squish method.
