If your seeds trays do suffer from slug attacks then there are 101 different things you can do. My favourite ways to deter slugs are:
- Half a grapefruit. It seems a shame to leave half a healthy grapefruit in the garden, so I suggest you eat most of it first.
- Broken egg shells. Not sure whether its the sharp pieces or the texture that slugs don't like, but its an easy eco-friendly option.
- Regualr checks. Before you water your seed trays take a quick look underneath. That way your seedlings will be safe and you will resist the temptation to reach for the dreaded slug pellets.
