How to: Seashell Plant Labels for Outdoor Garden Beds

Sharing is caring!

Every time we go to the beach, we always come home with seashells. It’s peaceful and serene and relieves my stress to walk with my girls along the shoreline picking up shells. Now we finally have a use for them – seashell plant labels for outdoor garden beds!

This garden craft works so well on a rainy day when you’d rather be out in the garden. Seashell plant labels make the best kid crafts after a trip to the beach, or any time you’re missing it.

Benefits of Shell Garden Markers

Coming from a beach bum, I am all about seashells in the garden! Here are some of my favorite benefits of this style of plant labels:

  • Embracing Nature – You’re repurposing nature at its finest. Add a tropical and fun element to your garden.
  • Permanence – Polish and make permanent your favorite shells. Waterproofing hand-painted seashells works way better than Sharpie plant markers and other tags.
  • Kid-Friendly – This garden craft is just as lovely as it is kid-friendly. Get your little ones – or even your teenagers – involved in making memorable and useful art.
  • Creative – Use fun craft supplies to make lovely designs that coordinate with your garden and its flowers and plants.
  • Mark Perennials – So many times we lose track of spring bulbs or those we need to dig up at the end of the season, like Dahlias. Mark them well so you know exactly where they are.

Choosing Seashells for Garden Labels

When choosing shells for garden labels in an outdoor bed, size matters and so does shape. Consider the length of the plant and flower names you need to write or paint.

My favorite shells to use for garden markers are clam shells and oyster shells.

  • I look for long, flat oyster shells to use for long flower names, such as Ranunculus and Snapdragon.
  • I found that shorter names like Zinnias and Dahlias fit perfectly on clam shells that I painted just like the beach.

Also consider the color of the paint and the color of the shell. Lighter colors work best on lighter shells. If you’re painting dark gray shells, you may need several coats of paint.

  7. Add more paint if necessary.
