An effective snail barrier

Slugs and snails can destroy a garden overnight if the gardener isn't vigilant. An effective and very frugal solution to this problem is newspaper.  Simply shred newspaper and spread it around the base of your plants. Then just dampen it slightly and sprinkle with bi-carb soda. The damp newspaper is a gourmet delight for the snails while the bi-carb acts as a poison to them.
