Just as everything starts to ripen or blossom, along comes nature's slime monsters to help themselves - ruining your best cultivated efforts. Snails and slugs loathe this stuff - it's ulta-heat treated volcanic rock that has popped like popcorn! It's incredibly lightweight.

Best of all, it sticks to the molluscs impairing their ability to travel to across to your most precious plants. Soon enough they turn away in search of more accessible foodstuff! It's all-natural, odourless and pet safe. Each bag contains 1 litre.

Simply sprinkle a thick ring, an inch or two, around the plant or across the top of the pot plant to form a non-traversable barrier. Also great to add to heavy soils to help aerate it.
