Garlic Wash Slug Control

Hosta Garlic Wash Recipe


We are always asked about how to protect hostas from being eaten by slugs and snails. Garlic wash is a really simple, cheap and safe way to protect your hostas without using harmful pellets. Here is a simple recipe that we use on the nursery.

  1. Take 2 full bulbs of garlic and add them to approximately 2L of water in a saucepan.     
  2. Boil until soft and squash with the back of a fork to release as much juice as possible.
  3. Sieve out skins and bits so you are left with a cloudy liquid concentrate.
  4. Dilute approximately 2 tablespoons to 5L of water in a sprayer or watering can.
  5. Spray or water over your plants once a week February-October.
  6. High dosage and more regular applications may be needed in wet weather.

Store outside in a cool dry place or in the fridge. Can be used throughout the season, make a fresh batch every year.

Thank you for this advice – so excited to try it – is it safe to use on strawberry plants , or will they taste of garlic?
Thank you
