The following plants are considered generally unattractive to slugs. However, some slugs are hungrier than others, and seem to have sophisticated taste. One way to beat slugs is to plant things they don’t like. This would include plants that would likely irritate their slimy little bodies such as plants with hairy or rough surfaces, fibers, sap or plants that are very aromatic or have thick, leathery leaves.
