I’ve found permeable mulches

[Daucus]

I’ve found permeable mulches and plants have all been great slug harbours. Bare earth is my preferred option as it is easy to hoe once everything’s under control. Having said that, it’s very wet here and the soil is pure clay, so it can get slippy in the rain. Straw on the paths over winter keeps them clear of most weeds, and it usually rots down in time for summer when it’s left bare. Hope that helps…!
