As seen during our appearance on BBC Gardeners World we use garlic wash as a slug deterrent on the nursery. Please find below the recipe that we use and find very effective. The quantities aren't exact and you can always alter them as you wish.
Open a window because it's going to get garlicky!
We are currently away at RHS Tatton Park this week so please bear with us as there may be a slight delay to orders being dispatched. Thank you for your patience.
