Oyster shells are a great addition to the garden. Oyster shells will help kill snails and slugs, keep away moles and de-acidify your soil. Since the shells contain calcium carbonate, which is essentially lime, they can raise the pH of acid soils.

Instructions

  1. 1

    Boil water in a large pot. Place the oyster shells in the pot for a few minutes to kill any bacteria.

  2. 2

    Take the shells out and let them dry.

  3. 3

    Wash and dry your hands to prevent spreading bacteria to the clean shells.

  4. 4

    Place dried oyster shells into your plastic bag, push all the air out of the bag and seal the bag shut.

  5. 5

    Put a towel over the plastic bag and lay both flat on a stable surface.

  6. 6

    Use a hammer to crush the shells until they are in fine pieces.

  7. 7

    Keep the towel around the bag and bring it outside to your garden. Spread the fine pieces and mix them into the top layer of soil.
