Copper collars round the base of the plants. It does work, honestly. My sister in law has been using them with great effect in her vegetable garden, they seem costly but do last virtually for ever so can be re-used time and time again.
I grow around 65 different hostas in pots and nearly gave the collection up a few years ago because of snail/slug damage, until I was told about copper tape around the pots, it really has mde a huge difference. Even in this wet weather, there is little damage done by snails ans slugs, though there are always a few which crawl up the wet and drooping leaves, but the majority which climb the pots just do not pass the copper.
