Select a field or area for the seedbed with well-draining silt-loam or clay-loam soils. Bromegrass needs a pH of 5.5 or higher, and it grows best with a pH of 6.0 to 7.0.
Prepare the seedbed for planting by lightly disking it with a tractor, or digging and raking a smaller area by hand, a few weeks before planting. Use herbicides if necessary to discourage germinating weeds.
Plant bromegrass seeds in a firm, moist seedbed in either spring or late summer.
Use a seed drill attachment for a tractor to plant bromegrass seed. Use a hopper-type fertilizer spreader calibrated for seed to broadcast bromegrass, or broadcast the seed by hand in small areas.
Plant seeds at a depth of 1/4 to 1/2 inch deep.
Use 20 pounds of seed per acre if you're planting bromegrass alone, or 5 pounds if you're planting in combination with other seeds, such as alfalfa, timothy or wheat. That equates to a planting rate of 50 seeds per square foot alone, or 15 seeds in combination.
Apply nitrogen fertilizer once in early spring at a rate of 50 pounds per acre, and again after each of the first two harvests, then fertilize annually.
