Anti-slug plants, or prevention through plants

Slugs devour everything in your garden, and you want to solve the problem by choosing the right plants? Very good strategy.

But before going any further, there’s an article I recommend you read, if you want solutions to your slug worries. It’s the article “30 natural slug pellets tested and reviewed”, linked just below. Read it, then come back. (Well… If you like)

Natural slug pellets

If you've discovered my blog, you're probably bothered by slugs and snails.

You'd probably be very interested in the 7 Steps to get rid of slug by attracting the Alpha predator I have designed with the help of Science, and The slug-proof garden Design I have made (with the help of dozens of scientific studies too).

It changed everything for me. I can finally grow lettuces, cabbages, strawberries and cucurbits without pulling the hair out of my head.

Don't hesitate, you'll probably save a lot of time!

Are you still there? Too good, so here we go!


I. Prevention with slugs: why?

Did you know that your vegetable garden is a modification of an original natural environment?

That’s right, because where your green patch used to be, there was probably a meadow or forest.

All that’s needed is for the original vegetation to be pushed back, torn out for aesthetic reasons, and a veritable island of novelty in the natural ecosystem is created.

With that,the soil is sometimes too young or too worked, and life (fungi, bacteria, multiple insects) hasn’t yet had time to build up.

This type of garden is often “invaded” by endless streams of slugs in spring.

This impressive landing of gastropods is in fact one of the symptoms of a young garden, or of a biodiversity that is not sufficiently present.

But if we know all this, if we’ve already read about it, if we’ve even seen Hervé Coves’ entire lecture on the subject, we may already have put in place the means to help bring our garden back into balance.

But… while waiting for the miraculous natural regulation, we are fighting with all our might to preserve our few lettuces: massive collections, walls of eggshells and ashes… It’s never-ending…

What if you could protect your cabbages and salads, while being the biggest lazy slob on earth?

Yes, it’s possible. Well… let’s just say it might make your job a whole lot easier.

“And how, may I ask?”

But thanks to plants, of course!

You’re going to plant a set of so-called “slug-proof” plants, whose combined properties will help protect the plants in your kitchen garden that you cherish so much.

In fact, it’s a preventive technique against the problem of slug invasion in the garden.

But why prevent?

As a general rule, it’s always more effective to prevent a problem than to treat it when it occurs (“cure” it). But above all, this method of prevention is excellent because, once the targeted plants are in the ground in your garden, they act on their own, and continuously. That’s their great strength.

That’s for the “why”. For the “how”, we’ll see right away!


II. Anti-slug plants: how to use them?

As you’ve no doubt gathered by now, there are 3 categories of plants among what I’ve chosen to call (for ease of reference) “anti-slug plants”:

  • Slug-resistant plants: slugs generally don’t eat them
  • Plants that repel slugs
  • Plants that slugs love to eat and that have a distracting effect



a. The first group of anti-slug plants: Slug-resistant plants

lamb's lettuce is a slug-proof plant

Choosing plants and flowers for your vegetable garden that slugs won’t eat is the first, most essential and undoubtedly best preventive solution.

Indeed, some plants have naturally developed resistance to slugs.

Some have a bitter taste, while others have hairy or fleshy leaves, hairs or prickles. Other plants give off a strong scent that helps to draw predators away from them.

Plants with these defenses are naturally protected from slugs, which will only eat them if there’s nothing else to eat.

These naturally resistant anti-slug plants should be used in the vegetable garden as plants that most often “serve” the gardener’s immediate objectives: either vegetable plants (vegetable production), or flowering plants (ornamental).

Each of these plants is, in essence, a princess to be protected from the bad guys: if the princesses are black belts in karate, they’ll naturally be better protected from immediate danger.

So, in practical terms, if you’re planting a vegetable garden, choose plants of this type: instead of green salads, for example, plant red lettuce, or lamb’s lettuce (more slug-resistant plants here).


The purpose of this article is to put into context the 3 thumbnail articles below, which address this theme.

It provides a more global view of this plant-based problem management strategy.

I try to address four points that I think are essential:

  • Why prevent slugs?
  • What are slug control plants? How do you use it?
  • Which slug-eating plant supplements are right for you?

Resistant and/or repellent vegetable plants

Distractive plants

In detail

b. The second group of anti-slug plants: Plants that repel slugs

Other anti-slug plants are those that are not only resistant, but even repellent !

If we take the example of the princess, the young girl would have a black belt in karate, but with huge biceps that would scare the bad guys away.

The aim is to use the strong damsel to protect other, more fragile and innocent girls: borage, for example, is a plant with a repulsive effect. We can therefore place it close to our lettuces, to keep slugs away from them as much as possible.

But you should know that there are many other slug-repellent plantsand these are just a sample.


c. The third group of anti-slug plants: plants that distract slugs.

As opposed to repellent plants, did you know that plants that are very popular with slugs are also of enormous interest?

The idea here – to use our 4-year-old example ^^ – is to protect the princess, by putting other princesses, adorned with diamonds and solid gold (and therefore “more attractive” (I know, that’s going a bit far)), in the path of the thugs.

So, for example, in the vegetable garden, the aim is to plant a host of dandelion ladies alongside your zucchini ladies. Slugs and snails prefer dandelion leaves to zucchini leaves, so the latter may fare much better.


d. Anti-slug plants: the winning combo

Of course, it’s best to combine these different strategies. Put your red lettuce lady (black belt in karate) next to a wall of borage (big biceps), surrounded by dandelion ladies: you can bet that lady lettuce will be in top form!


III. Anti-slug plant supplements :

Planting anti-slug plants is an excellent way of intelligently controlling slugs in the vegetable garden.

However, 2 things are equally important:

  • Encourage “biodiversity magnets”: plant essences with properties that attract numerous insects and animals. This biodiversity is essential to your garden’s long-term equilibrium, and also helps speed up its “return to equilibrium”. Borage is an excellent example of a plant with multiple benefits.
  • Encourage local species: this is an important point, so as not to accentuate the discrepancy between your garden’s ecosystem and the local ecosystem. It’s also a great way to encourage biodiversity in your garden, as the plants that live there are better adapted to the local species, which makes sense because they co-evolve.

Even better! Follow scrupulously these 7 steps 👇

This is the action plan I devised following the findings of dozens of scientific studies on the subject.

I owe the success of my cabbages, salads, strawberries and cucurbits to it.

the seven steps to definitly get rids of slugs



The plants I call “anti-slug” plants are of enormous interest for slug management in the garden. They act via a preventive mode, and their action is permanent throughout the season.

The combination of resistant, repellent and distracting plants provides effective protection against slugs. You can also use barriers, one of the most effective of which is copper (see article: copper: test and comparison).

However, we mustn’t forget to continue attracting slugs’ natural predators to the garden, without which sustainable rebalancing will be impossible.

If you’d like to find out more about slug control strategies, don’t forget to scroll down to the middle of this article, where I’ll be presenting the 3 articles specific to each technique.

Even better! Adopt copper slug netting.

This is the copper barrier I designed following my many slug barrier tests.

I owe the success of my cabbages, salads, strawberries and cucurbits to him.

A passionate experimental vegetable grower, I had huge slug problems during my first 2 years of vegetable gardening.

Nothing (eggshells, ashes, etc.) seemed to work…

And yet, if the Internet was to be believed, everything was supposed to work…

In short, faced with an obvious problem of misinformation, I decided to take action: I tested all the famous “slug barriers”, so as to have a clear mind, and know what to do.

I filmed my (13) tests(here, in French)

The results were crystal clear: nothing was able to effectively block the path of slugs and snails, except Water, usable with trenches at least 5 cm deep and 10 cm wide, or Copper, if used vertically, if its height is at least 7 cm

But a water-based barrier is difficult to implement, and copper is expensive…

It was by turning to scientific studies that I found the solution: adopting a slug predator in the garden, present everywhere in the world, which has a huge regulatory effect on them.

The studies show it. And I called this predator the Alpha predator of slugs.

Using dozens of scientific studies again, I constructed an action plan of the most effective arrangements to attract this Alpha predator to the garden sustainably, and to see it multiply by itself, year after year, season after season.

And to get rid, definitively (and intelligently), of slugs.

I have gathered these 7 steps in a digital book that I propose on this site, and at the end of the book, there is also a video training module on designing a slug-proof garden.

You can find this digital book (which contains all of this) by clicking here

And what if you don’t get rid of your slugs by following the advice in this book? It’s simple, I will refund you in full (but it will work, if you follow the instructions properly).

So, don’t hesitate to discover the simple 7 Steps that can change your springs
