Ten to twelve organic milkweed seeds and red clay are mixed and dried. Each clay ball approximately 1/2" in diameter. Germination rate 66% (Ample seed count in each each seed ball ensures multiple germinations per seed ball). Red clay protects seeds from rodents and other foraging animals and birds. Plant clay seed ball in the fall and winter so that the seeds will naturally cold stratify for increased germination rates. Seed balls planted in the spring may take until mid summer to sprout depending on moisture content of soil. Monarch butterflies lay eggs on the milkweed plant and the caterpillars that hatch feed on the leaves. Once established, the milkweed plant will grow each year from the root stock. The spread of the milkweed plant can be easily controlled by mowing areas where the plant is not desired. It is recommended to gather pods in the fall to control propagation. The seeds can be donated for redistribution to various organizations such as Monarch Watch. PA Department of Agriculture Seed License ID: 007FJY
