In case you are a gardener living in Europe. Especially, if your garden is near the forest. The chance of slug swarming over your plants is high. I believe you have experience with them every year during the growing season.

They are invasive types: Aron lusitanicus (common slug in Germany), Aron rufus (orange slug), and Aron vulgaris (brown slug) that I caught thousands of them in my garden. Especially, when I plant high-protein-vegetables like cauliflower, broccoli, any type of kale, and all the sunflowers. Anything sweet or delicious for us, they would love it as well.

…

As I grew plenty type of veggies and other plants in the garden last year. I have collected a list of plants slug does not like.

Anything hairy they hate it like watermelon, cucumber, bean, and peas. They do not swarm on the hairy plant + climbing plants. So if you want to plant anything outdoors without any protection. Make sure your plants are resistant to the slug. So in this post. I’ll be sharing the list of plants and veggies that you can plant outdoors without additional protection from them.

How to control slugs organically

These are the methods you can do to control slugs in the garden. One of them that is effective and easy to care is introducing ducks into your garden. They love eating slugs.

Except for ducks. Promote these animals in your garden. Though it might not easy to do, it’s great in long term. I also have plenty of lizards in my garden.

• Hedgehogs
• Toads
• Lizards
• Songbirds
• Shrews
• Moles
• Harvestmen
• Beetles
