Made in-house by our own earthy little family. Our seed bombs are made of a mix of pollinator seeds packed into a ball of earthenware clay and organic soil. The idea of a seed bomb started as part of a guerilla gardening movement to rewild neglected areas. Do you see a place that could use a little love from Mother Nature? Simply toss the seed bombs there and Mother Nature will take care of the rest: over time the seed bombs will naturally break down, and the seeds will sprout a variety of wildflowers. Each recycled paper pack contains 4 seeds bombs.
