Join My Little Apothecary at the Amherst Farm and Craft Market at the Amherst Garden Center! We'll be making Seed Bombs using recycled paper and local plant seeds. What is a Seed Bomb? A Seed Bomb is a little nugget made of clay or recycled material and seeds that can be thrown on any ground. Wait and watch the seeds grow and make a space beautiful! Each child will go home with one seed bomb.
