No digging or tilling required! Just place these Drop & Grow Flower SeedBallz in the soil. Loaded with seeds, each of the 8 truffle-like clay balls grows clusters of flowers. They're new and improved with minerals added to aid in the "breaking down" process. Do not bury deep; keep moist. Store SeedBallz in a dry, cool place. They are hand-rolled by individuals with developmental disabilities in the USA.
