Fodder grass grows quite fast, and I was thinking that will generate lots of mulch and should be good. But it grows tall around 3 feet and very dense and after cutting, after 15-20 days, grows back to the same height, especially in rainy season. Also wild pigs nest in between, so it has become a threat.
So thought of managing them bit differently. Just kept rows of grass 10 feet apart and all in between grass were uprooted. In the rows added, mexican sunflower and glyricidea also.
