Jonathan Green Pasture Grass Mixture contains elite forage grasses that are palatable and easy for grazing animals to digest. This is the ideal grass seed mixture for paddocks and pastures. Jonathan Green’s Pasture Mixture is the best choice for grazing horses and other livestock because these grasses are free of endophytes which have been known to cause illness in some grazing animals if the majority of their diet contains endophytic turfgrasses. This seed germinates 10-21 days.
