Every year the same problem: I barely put out young vegetable plants and the slugs have eaten them to shreds. I've already tried slug pellets, but that's too chemical for me and I'm worried about the hedgehogs in the garden. Is there an alternative that actually works?
Trap plants work, but honestly they're just a supplement, not a complete solution 😅 The slugs will just eat your vegetables *and* the lettuce. What actually helps me a lot in my own garden: stick copper tape around the beds (slugs hate it) and especially go out at night and collect them - sounds like a hassle, but after a week or two the problem usually sorts itself out. Plus: check the soil under pots and boards in the morning, that's where they hide during the day 🔍 If you really want to stay chemical-free, collecting them without alternatives is way more effective than baits alone.
Have you tried giving the snails some competition - like planting some decoy plants such as lettuce separately, stuff they'd rather eat than your vegetables? 😅 In practice, a combination really works best: snail fences (those copper things actually keep them away), picking them off regularly (yeah, it's annoying but it works), and if you've got the patience, collecting them in the evenings and relocating them. Also beer in shallow bowls - they go for it and drown in it - not pretty, but effective. For young plants you can just put plastic cloches or netting over them until they get bigger. In my garden there are fewer of them since I've created more hedgehog-friendly spots (leaves, bushes) - they eat snail eggs too, so there's less breeding 🦔
Slug pellets aren't the only chemical solution - there are also nematodes that eat slug eggs and are completely non-toxic to everything else. The problem with trap plants and barriers is that they don't work well on their own, but together they work way better: if you put copper tape around your beds at the same time, scatter coffee grounds, and grow your young plants under a net until they're bigger, the slugs just lose interest. Hedgehogs will thank you for it too, because they can eat the slugs themselves if there aren't too many.
For me, a combination of copper tape and regularly hand-picking has worked best. You lay the copper tape around your raised beds or directly around the plants - slugs just don't like the feel of it and they'll avoid it. The thing is, you've got to apply it really consistently, otherwise they'll still find a way in. And hand-picking sounds annoying, but if you go out in the evening or morning for a quick check and remove the slugs by hand, it makes a huge difference. I do this two or three times a week during peak season.
Just make sure the copper tape doesn't get rusty and brittle though - once it's no longer smooth, it barely works anymore. A real pitfall that people miss: lots of folks forget to check underneath pots and around the edges of the beds. Slugs hide in cracks and crevices during the day, and if you're only looking on top, you won't catch them.
The nematodes that were mentioned earlier are a good thing for the long term, but they take time to work. Combined with copper tape though, you've got a pretty solid solution without chemicals and without putting hedgehogs in danger.
