Moated Gardening
An idea for preventing slugs getting to your plants.
Monty Don, when doing Gardeners World, prepared some raised beds by surrounding them with wooden planks which were topped with copper strips.
The idea being to prevent slugs entering the bed and to gradually remove the slugs already within the soil.
An idea I had on this - as a sort of variant, is this:
Create beds within a garden, then form channels around these beds through which water will flow.
Each bed being effectively isolated by the flowing water, and thus preventing slugs gaining access to it.
Perhaps impractical, on the other hand, potentially very attractive and interesting.
A thought, anyway.
