Key benefits

  • Gives pots and terrariums a natural coastal top dressing
  • Improves drainage and aeration when mixed into compost
  • A natural barrier against fungus gnats
  • Washed, dried and crushed whelk shells in a 1kg bag
  • Packed in a recyclable, hand-tied paper bag

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.

How to use
  1. Spread the shells over the soil surface as a top dressing
  2. Or mix them into compost to improve drainage

What is your returns policy?

Changed your mind? You can return pots, gifts, accessories and other non-plant items. Email hello@growtropicals.com with your order number within 14 days of delivery, then send the item back within 14 days of telling us. You pay the return postage.

Items must come back unused and in their original condition. If an item has been used, we may reduce your refund by the value it has lost, and for used items this can be the full price.

Live plants cannot be returned because you have changed your mind, but they are covered by our Live Arrival Guarantee.

If something arrives damaged, faulty or wrong, email us with your order number and photos and we will put it right at no cost to you. Full details are in our returns policy.

When will my order arrive and how much is shipping?

Choose your delivery speed at checkout. Express orders placed before 1pm are dispatched the same day, otherwise the next working day. Standard orders are dispatched within 2 to 3 working days and Economy orders within 4 to 5 working days. Once dispatched, every order travels by 24 hour tracked courier.

Delivery is free on orders over £60 with Economy, over £100 with Standard and over £150 with Express. Below that, the charge depends on your basket total and is always shown at checkout before you pay. The full price list is in our shipping policy.

Orders without plants are dispatched Monday to Friday. If your order also includes plants, it goes out Monday to Thursday so the plants are not left in the courier network over the weekend. Delivery can take longer at busy times such as Black Friday and Christmas.
