In this video, Shirley shows her viewers an effective way to multiply your red fountain grass in order to create more grass from a single plant. After the growing season, find a large, overgrown patch of grass and use a shovel to dig out a section by the roots. After planting the grass in a pot, it is crucial that you shear the top of the plant so that the grass is only 4 to 5 inches tall. This will ensure that the plant focuses on growing roots rather than its blades at the moment. This method of dividing and multiplying red fountain grass will enable any gardener to expand one's garden using only a single plant.
