Q.How Much Powdered Red Clay Do I Need To Make 100 Clay Seed Balls
I am restoring open space and want to place 100 clay seed balls with local grass seeds. I have 5 different local species. How much powdered red clay should I purchase to make 100 balls?

It depends on the size of your seedballs and the ratio you use. Our article says 5 parts clay to 2 parts potting soil or humus and 1 to 2 parts seeds, but I've also seen 5 parts powdered clay to 3 parts compost and 1 part seeds. I have no idea how much a seedball weighs, but doing some sleuthing at ready to use seedballs online, I would guess about one pound would be more than enough.
