With this matrix, you can make your own easily and without the effort of procuring supplies and the mess of mixing the clay powders and composts. In addition to being a great tool for agriculture and guerrilla gardening, making seed balls is an easy activity with an outstanding success rate. It's a great way to have fun while teaching environmental ethics.

Seed-balls.com makes the matrix to have a very high organic matter content, which mimics the top horizons of the soil, which favor germination. The three types of compost offer a balanced chemistry and slightly acidic-neutral pH, which seeds and seedlings love.

Seed balls were popularized in the late 20th Century by Masanobu Fukuoka, but have been around as an early no-till agriculture practice for thousands of years. because of the ease of dispersal (just tossing the ball on the soil, or throwing it over a fence), it has become a favorite of guerrilla gardeners.
