Slugs and snails
I am so impressed with this concoction that I feel I have a duty to broadcast it to everyone. I have been plagued for years with slugs and snails eating my plants, as soon as they poke their heads out of the soil, they are attacked. I have tried all sorts of things, beer traps, copper wire and always resorted back to the dreaded pellets.
I saw this concoction on an episode of Gardens World and tried it and it really does seem to have done the trick. All my plants are healthy and not a slug or snail in sight.
To make: is one whole garlic bulb, crushed or roughly chopped in a saucepan of 1 litre of water, boil for 5 minutes, leave to cool, strain off garlic to leave just the liquid, transfer to a bottle and keep it in the fridge. To use, dilute 1 tablespoon of garlic water into 1 litre of water and spray plants and surrounding soil. It's cheap and I have found it very effective.
