Hemarthria altissima seed production is low, but the long, decumbent stems root readily at the nodes making vegetative propagation through sprigging an accepted commercial practice. It is propagated by cuttings planted into wet soil, early in the season if unfrosted planting material is available, or in late summer having allowed a build-up of planting material during the peak season. It appears to give more successful establishment results if the cutting nursery is fertilized with nitrogen 2‒3 weeks before harvest. Freshly mowed stems and stolons of 2- to 3-month old grass are spread over a well-prepared seedbed, partially covered with a disk harrow and rolled to compact the soil around the cuttings. Planting rates of 1 t/ha vegetative material are recommended on "clean" ground or 1.5‒2 t/ha if weeds or other grass are likely to compete. Livestock should be withheld until the grass is established, even cutting and conserving the initial growth flush to ensure establishing plants are not pulled out. When the grass reaches 10 cm or more high, susceptible weeds can be controlled with dicamba. Broadleaf herbicides should not be used for weed control if legumes are planted with the grass.
