Piper Sudangrass is a fine-leaved, warm-season bunchgrass. It will produce large amounts of organic matter, cycle nutrients, suppress weeds, and loosen soil with its deeply penetrating roots. An excellent catch crop for excess nitrogen, sudangrass reduces nematode populations as it decomposes. It prefers hot, dry weather (like corn) and withstands drought-like conditions easily. Sudangrass grows quickly and needs to be mowed regularly to control height (up to 7 ft.), increase root structure, and add more organic matter to the field. Plant late spring to early summer once the soil has warmed to at least 60°F/15.6°C; earlier sowings can be outgrown by cool-weather weeds.
