Made from composted cow manure these pots are as natural as can be! (Don't worry, they don't smell). Whether starting a seedling on a windowsill or in a greenhouse setting, CowPots will hold their shape until the seedlings have grown and are transplant ready for the garden or field. CowPots are planted directly into the ground with the plant. There is no need to remove, break or pierce the pot; it breaks down naturally into soil without restricting the plant’s growth.
