Hydro mulching is the process of protecting seed and vegetation with a slurry coating of mulch applied with a sprayer. The history of hydro mulching is over 4 decades deep. As such, the industry has developed many applications and benefits over conventional mulching operations.
"When hydroseeding was first developed, it primarily was a mix of seed, fertilizer, and water. Then in the early '60s they incorporated mulch, which became hydromulching, creating a one-step process rather than two. Sometimes there is a need to hydroseed to get a better seed/soil contact, then come back over with a mulch cap of anywhere from 800 to 2,500 pounds per acre."
