When your container garden starts doubling as the neighborhood slug and snail salad bar, it’s hard not to take their shenanigans personally. Instead of sulking (okay, maybe I did sulk a little), I decided to turn the problem into a small project and make this easy DIY copper accent planter.
Think simple wooden box,…..
a touch of metallic magic and one easy hack, hidden in plain sight, that helps keep snails away.
Ready to see how it’s made?
What you need
For this tutorial you’ll need a plain old planter, copper, tape and copper mesh. I used a wooden box as my planter, but you can use whatever you have on hand. We’ll use the copper mesh and tape to create a designer obstacle course that deters adventurous snails.

How to make a snail deterring copper accent planter
Just in case you don’t have a ready made planter lying around waiting for a copper makeover, I’ll quickly share how I “plant proofed” an ordinary wooden box. This is what it looked like before the transformation.
From wooden box to planter
Wooden boxes make great planters, but you need prep them first, so they don’t rot and go all muggy. Start by drilling a few drainage holes in the bottom.
Seal the interior of the planter to protect it from water damage. I used a poly wax sealer that’s plant safe once it cures.
For the outside, I wanted something darker to make those copper accents pop. Sadly, I couldn’t find the right color poly wax, but it’s easy enough to solve. You can “stain” the exterior with watered-down, black acrylic paint before applying the poly wax sealer.
It creates a lovely effect.
The biggest risk of water damage on a wooden planter is the bottom. That’s where extra water pools, and over time it can cause the wood to swell and rot. Adding a heavy‑duty plastic liner gives the box a fighting chance and helps it last longer. I just repurposed an empty bag of doggie food.
I stuck the liner down with aquarium silicone.
So that’s the prep work done. Now to add those snail-deterring copper accents to the planter.
Adding Copper Accents – a three- pronged approach
Time to give this simple planter its copper makeover. We’ll add three details that all play a part:
- Four round copper feet raise the box off the ground, reducing those damp, easy access points and hiding spots that slugs and snails love;
- a copper mesh creates a frilly guard around the top, like a well‑dressed bouncer holding a “do not enter” sign;
- and a small copper knob pulls the whole look together, letting the snails know this planter is for members only.
Let’s start with the feet. I used four plastic beads to make mine. Square blocks of wood, copper pipe offcuts, or little rubber feet will work too. To give the feet a blingy, snail‑deterring finish, I wrapped them in copper tape. It’s this thin, flexible strip of copper with adhesive on one side. A bit like metallic washi tape.
Because it’s so soft, it creases and folds easily, which makes wrapping it around curves a breeze.
Trim away any excess and then nail or screw the feet onto the bottom of the planter.
To add a frilly guard around the top of the planter, I used copper mesh. It’s a soft, knitted ribbon of fine copper strands that looks a bit like a detangled pot scourer. Because it’s made from real copper, the mesh adds a warm, shiny trim and doubles up as a gentle barrier that should convince snails to snack somewhere else.
Make sure your mesh band is at least 5 to 7 cm (2 to 3”) wide to maximize the deterring effect. Use a stapler to attach the mesh to the top of the planter.
For a final decorative touch, I screwed in a small doorknob and covered it with copper tape. That stuff comes in so handy. I used the same trick to upcycle cardboard into costal fish décor. It’s a quick way to echo the copper accents and make the whole planter feel more custom.
Now all that’s left to do is add the salad bar plants.
With the last plant tucked in and the soil brushed off, your DIY copper accent planter is ready for guard duty. Even if the slugs and snails don’t get the memo straight away, you still end up with a custom piece that makes your container garden feel just that tiny bit more special.
FAQ
Does copper really bother slugs and snails?
Think of copper as a tiny “electric fence” for slime trails. When slugs and snails slide over copper, there’s a mild reaction between the metal and their slime that feels pretty unpleasant to them, so many will turn around and look for an easier salad bar instead.
Will a copper accent planter stop all slug and snail damage?
I wish I could say yes and hand you a shiny, slug-proof trophy, but nope. Copper can make life trickier and often slows them down, but a determined muncher can still find a way. That’s why I treat copper as a stylish extra layer of protection, not a 100% guaranteed force field.
Is it safe to grow herbs and veggies in a copper accent planter?
Absolutely. In this project the copper lives on the outside (and in mesh form), not mixed into the potting soil. As long as you’re not drenching your soil in copper, herbs and veggies should be fine.
Do I need to replace the copper mesh?
Copper mesh lasts or years outside, so you won’t need to replace it for a loooong time. Just a heads up – the shiny copper colour will fade and darken as it ages, but that’s normal and it still works. You only need to replace the mesh if it is torn, bent out of shape, or no longer makes a neat band all the way around the planter.
What else can I use with copper to protect my pots?
Copper works best in a team. Add a gritty barrier like crushed eggshells or sharp sand, pop a beer or yeast trap nearby to lure repeat offenders away, and raise your pots on bricks or stands. Think of it as building a tiny obstacle course that gently suggests your plants are “closed for business.”
Why not just use slug pellets?
Short answer: because I like bees, pets, birds, and all the other good garden guys hanging around. Pellets and harsh chemicals aren’t selective, so I prefer using natural tricks like raised pots, gritty mulches, and frilly copper bits instead.
Do slugs and snails actually have favorite plants?
They do yes. Tender new growth, leafy greens, young seedlings, and juicy flowers are basically their version of a five-star buffet. Those beautiful pansies are a snail magnet.
Poppies with hairy stems are safe though.
