Slugs / snails and Hostas
I've tried a few solutions to try to stop slugs and snails having my hostas for lunch, never with complete success.
This year I've applied copper tape to all the pots and, although it's still quite early days, not one has been attacked. I would provide a word of caution though - when flattening the tape down use gloves. The edges of the tape are extremely sharp and I didn't realise I'd shredded a couple of finger tips until I notices blood running down my hand!
