Use these instructions from KidsGardening.org to make seed balls as a fun and inexpensive way to sow native plants and flowers! Seed balls are a small collection of seeds, compost/soil, and clay. They are commonly used to revegetate areas burned by wildfires but can also be used on a smaller scale in home gardens and classrooms. 

• Clay (can be found at craft stores)
• Potting soil or compost
• Seeds (easy-to-grow varieties)
