In my opinion, snails are gross. I’m sure they have their place in the food chain, but I wouldn’t miss them if they went extinct.
Luckily, I’ve never had a big problem with them in my garden. Sadly, I have no tips to share. Shannon has some ideas so I’ll stop putting words in the way of her response and let you get to it.
With all the rain we have been getting in Austin lately (side note: yay!!!!), I have seen lots of snails on the prowl. While they look harmless in their little shells, they can do some damage to your plants.
Last year I had a big problem with them on my broccoli, cauliflower, and cabbage plants. They were all over and it was gross. I think they even had babies…even grosser. I did my best to pick them off and toss them far away when I caught one red handed. This year I plan on doing that as well as trying these two methods I have read about recently.
Copper – apparently snails and slugs don’t do well with copper, and by don’t do well I mean I think it gives them some sort of electric shock to their nerves. I’ve seen people line their raised bed or pot with copper and that seems to work. Others have laid pennies (be sure to get ones that are dated before 1982) around the base of their plants. There are some other copper options like copper foil and copper sulfate that could be used as well. I am going to see what affordable copper options I can find at my local hardware store.
Egg Shells – roughly crushed egg shells are another method to try with snails. I’ve heard that snails and slugs won’t crawl over them because it is like crawling over broken glass…ouch! So save those egg shells from your breakfast. I keep mine in the fridge and when I am ready to use them in the garden, I bake them for 20-30 at a lower temp, then once they have cooled I crush them all up. (Just a side note: crushed egg shells have many uses in the garden…for example tomatoes love them.)
