1. A method for forming an erosion control device, the method comprising:
placing a composted filling into a first tubular mesh enclosure formed from a mesh material having a nominal opening size of between approximately 0.125 inches and approximately 0.5 inches, said first tubular mesh enclosure having a first opposing pair of ends, at least one of said first opposing pair of ends sealed, said first tubular mesh enclosure defining a first length and a first generally oval cross-section defining a first major diameter, a first ratio of said first length to said first major diameter greater than approximately 100, said composted filling being compost containing less than about 5 percent by dry weight of inert or foreign materials, said compost produced according to an aerobic composting process meeting a United States federal government composting regulation, the compost being weed seed-free, disease-free, insect-free, refuse-free, and contaminant-free, the compost comprising compost particles wherein at least 70% of the compost particles pass through a 0.375 inch sieve and no more than 2% of the compost particles are longer than 3 inches, the compost having a moisture content of less than 60%, the compost comprising less than 1% by dry weight of inert, foreign, or man-made materials; sealing at least one of said first opposing ends; placing a plurality of filling supplements into said first tubular mesh enclosure; providing said first tubular mesh enclosure to a location prone to sediment-containing water flow; compressing said first tubular mesh enclosure to have a substantially flat-bottomed cross-section; securing said first tubular mesh enclosure to a surface; attaching a second tubular mesh enclosure to said first tubular mesh enclosure; and inserting a living plant or plant seed into said filling through a hole created in a side of said first tubular mesh enclosure. |
