Throw a seed bomb at the ground and watch the flowers grow! Seed bombs are little nuggets of clay, compost, and native seeds that you throw at the ground. You can throw them in your yard or in a neglected space to help turn it into a flowering wonderland. Plant your seed bombs in Spring, Summer and early Fall and make them out of flower, herb, or even vegetable seeds. You just make'em and throw'em! When you throw your seed bomb, it will break apart as it hits the ground and a gentle rain will soon help the seeds begin to grow. Watch the video below to find out how.
According to Sean Sheppard, of The Backyard Farmer in Richmond, Virginia, "plants are tough. We often see them busting out of the sidewalk or through an impossible crack in a building, but they manage. Our seed bombs are basically a start-up for the plant, providing nutrient rich (from the compost and azomite) but stable (from the clay) growing medium. If the plant can germinate and use the nutrients in the seed bomb to stay alive for a few weeks, it will eventually find other sources of water and nutrients as it gets bigger and stronger."
Making seed bombs is a great activity to do at home or at school. Here is the Backyard Farmer's favorite recipe for
Making Your Own Seed Bombs:
