A note about seed balls:
Seed balls, also known as seed bombs, protect the seeds from erosion, foraging, and many other factors. This protective property often results in a slower germination cycle. Wildflowers are also highly variable in their germination rates. Please be patient with your seed balls. If you placed them in a suitable location, soil, and climate, when the seeds are ready, they will grow!
