Seed balls are carefully selected non-GMO seeds rolled in our special blend of worm castings & 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. Supplied in a long lasting timber counter display with an assortment of 30 tins of seed balls. Typically there are 5 varieties of Seed Balls, depending on time of year and availability of seeds: Bee Friendly Flowers, Kitchen Herbs, Field of Poppies, Leafy Greens and Cottage Garden Flowers.
