The Grass Seed Certification program establishes the genetic purity and germination of varieties, blends, and mixtures. The certification process begins with the proper field history before production and continues through the bagging of a grass seed lot with every step independently verified by Seed Certification personnel. Each buffalo grass seed lot to be certified is sampled by Certification personnel and tested in the state seed laboratory, so the grass seed you buy is the seed that was tested If even one standard in this process failed, the lot is uncertified. You can rest assured that your buffalo grass seed is certified!
