Peckish No Grow Seed Mix is a special blend that uses ingredients that will not grow in your garden. Ideal for gardeners! All the seed?s husks have been removed so the mix is 100% edible. The ingredients have also been flaked or kibbled which damages the endosperm and prevents them from growing* ? this means there will be no weeds! This mix also contains our Calvita? Vitamin Pellet, a unique blend of vitamins and minerals to help garden birds stay healthy. Furthermore, our Peckish No Grow Seed Mix is now in plastic free packaging so you can feel even better about feeding the birds.
