Hydromulch is a mixture of fertilizer, seed, and shredded wood bound by a sticky, water-based compound, which helps the hydromulch to stick to the soil on hillsides and steep slopes.
Hydromulch seed includes a mixture of different grass seeds.
Some of the grass seed immediately begins to grow and the other seed sprouts up to 36 months later. Hydromulch prevents erosion and other damage caused by severe wildfires allowing the land to be reclaimed. In July of 1993, a military supply ship loaded with cargo containers docked at Sunny Point Military Ocean Terminal 30 miles south of Wilmington, North Carolina. When the cargo containers were opened, a swarm of adult Asian gypsy moths emerged. The ship was ordered back to sea.
