Product Information

Give your houseplants and terrariums a natural coastal touch with Shell on Earth’s Crushed, Washed & Dried Whelk Shells. Packaged in a fully recyclable, hand-tied paper bag, these shells are a beautiful and sustainable addition to your indoor garden.

Sustainably sourced from Shell on Earth’s family seafood processing business on the West Coast of Wales, each batch is carefully cleaned, dried, and crushed to create a versatile planting material that looks as good as it performs.

Perfect as a decorative top dressing for indoor plant pots, succulent arrangements, and terrariums, the shells also offer practical benefits — improving drainage, aeration, and helping to reduce fungus gnat infestations naturally.

Uses & Benefits:

  • Decorative top dressing for plant pots and terrariums

  • Mix into compost for improved drainage and soil health

  • Natural barrier against fungus gnats

  • 1kg bag 

By choosing Shell on Earth, you’re helping to reduce waste in the UK fishing industry, where over 5,000 tonnes of shells are discarded each year.

As a natural marine product, occasional traces of organic material may remain. Any sea aroma will quickly fade once opened and won’t affect performance.
