Seed balls are carefully selected non-GMO seeds rolled in our special blend of rich compost (for nutrients), mineral clay (to protect the seeds from birds and insects) and a sprinkle of chilli powder (to deter snails and slugs). * Each tin contains 24 balls * Each ball has 10-50 seeds depending on the seed variety. Our seed balls are lovingly rolled in our factory in Sydney. Scatter and grow. Kitchen Herbs Seed balls typically include Parsley, Basil, Chive and Corainder.
