What are seed balls?

Introduced in the 70s, seed balls are a form of “guerilla gardening” whereby seeds, soil and clay are mixed together into tidy germination bombs that are said to have an 80% higher success rate than simply broadcasting seeds onto soil.  Adding red potters’ clay to the mix protects the seeds from being blown away by wind or consumed by insects or birds.  Generally, seed balls don’t require watering and you should NOT bury or plant them.  Simply toss them in a vacant lot, your front yard, or a wildscape situation like a ranch or roadside.  Wait for the rain to melt away the clay casing, and nature will do the rest.
