UK wildflower seeds, clay, peat-free compost. The balls are made from a mixture of UK wildflower seeds, clay, peat-free compost and chilli powder. By being encased within the balls, the seeds are protected from being eaten by seed predators (such as birds and mice). Once enough water has soaked through the clay, the seeds inside will begin to germinate - helped along by the nutrients and minerals contained within the ball. The chilli powder continues to deter slugs and snails while the seed ball slowly degrades and the seeds sprout. They---re really easy to use - simply scatter on top of soil or compost (no digging or expertise required), water and nature will do the rest.
