Cultivation Propagated from seed. This grass rapidly becomes sod-bound if sown pure, and is nearly always sown in mixtures with alfalfa, sweet clover, red clover or Lotus corniculatus. Growth starts early in spring with a further period of growth in early autumn under favorable moisture conditions. 2 O 5 based on soil needs. Nitrogen fertilization is required for optimum hay, pasture or seed yields in most areas.
Plants spread rapidly from rhizomes.
Harvesting Bromegrass is long-lived if irrigated, fertilized and harvested properly. It provides palatable pasture and hay if not too mature. It resists over-grazing and trampling, but will not persist under close grazing. Old, unproductive, sod-bound swards may be improved by heavy disking and overseeding with a legume or by applying nitrogenous fertilizer in spring. In some areas, such as Kansas, it becomes sod-bound just a few years after planting.
