Recipe for garlic spray
Finely chop two or three large cloves of garlic after removing the protective, papery skin around the bulbs.
Mix the garlic with one tablespoon of vegetable oil, one teaspoon of liquid soap and 1 litre of water, stirring well.
Spray hostas, brunneras or anything slugs/snails enjoy
Hope this helps
