How they Work
A seed bomb is a little capsule with everything you need to grow a plant all bundled up. The clay has lots of root-encouraging nutrients. The Worm Castings will give the seeds a nice fertilizer, good for land that hasn't been cultivated or worked on for a while. The indigenous seeds are custom made for your area. They will know how to grow given the conditions.Now all they need is a nice rain. The perfect time to throw these is right before a light rainy season. The rain will melt the clay to expose the seeds, and your seed bombs will grow.
