Grow weeping love grass in well-draining soil with full sun exposure. Loosen the soil before spreading 3 to 5 pounds of grass seed per 1,000 square feet of land. Cover the seeds lightly to assist germination -- no more than 1/4-inch in silt loam soils or 1/2- to 1-inch in sandy soils.
Water the seed bed regularly during the first month after planting to keep the soil evenly moist most of the time. Afterward, provide the grass 1 inch of water every week, unless supplemented by rainfall.
Protect the ornamental grass from livestock that find it palatable. If the grass is susceptible to grazing livestock, consider enclosing the area in a wood and wire fence. Keep the fence 6 feet high and use high-tensile or barbed wires to keep the animals out.
Divide weeping love grass every three to four years to prevent them from dying out in the center. Cut back the previous year’s growth down to 6 to 8 inches with shears. Determine how many clumps you want to divide the grass into, depending on its size, so each features its own roots and grass blades. Dig out the clump from the soil to reveal its roots. Cut through the roots to divide the clump into smaller sections and transplant them to other parts of the yard.
