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.

Hi I’ve tried this, spraying regularly and it is helping but still some nibbling on some plants. Are there any varieties that seem to be less attractive to slugs and snails???
