Hi all, M father recently purchased a piece pf property to retire on and has had it cleared and a home put in. His propert is 2 level plots seperated by a hill roughly 15-20 degrees and 10 ft up the embankment. He has been looking for something to plant on the hillside to stop or at least drastically slow erosion. What I told him to consider was some stuff the highway department uses . It looks like a "sheet" of hay , they unroll it on the shoulder of the road spray something blue on it and in a few days grass is growing in it. Does anyone have any clue what this is. Or any other ideas to help remedy this? Thanks for any input.
