Anybody have any experience hydroseeding with Sideoats, Big Bluestem, Switchgrass, Little Bluestem, and Indian Grass? We have got this job as a sub on a new high school project. 60,000 square feet to be seeded with the above seed. In the past, when hydroseeding wild flowers, we broadcast seed then mulch over. Would the same process work here or should we mix the seed in the slurry? Thanks in advance!!!
