  According to the University of Colorado, ornamental grass is an effective way to add varying textures to the yard. In fact, you can grow ornamental grass to contribute interest in the summer with blooming flowers and in the fall with dramatic foliage. Growing ornamental grass at home allows you to divide the plant and put it into in different locations without a trip to the nursery.
  
  

Timing

• Timing is an important consideration when dividing ornamental grass for use in other areas in the yard. Warm season ornamental grass, such as Hameln Grass, Miscanthus Adagio Grass and Prairie Dropseed Grass, should be divided any time between the spring and midsummer months. Avoid dividing this grass when it is flowering, however. Cool season grass types, such as Karl Foerster Grass, Autumn Moorgrass, Blue Oat Grass and Tufted Hair-Grass, can be divided in the early spring or early fall months. If you are dividing evergreen or sedges, do it in the springtime.
  
  

Dividing Methods

• Division of ornamental plants should be done on a rainy or cloudy day to keep their root systems from drying out. Creating more ornamental grass to plant is no good if it results in a dead main plant. According to Blue Stem Nursery, you can jam two potato forks into the crown of your ornamental plant. The crown is the center of the plant. Jam the forks, so that they are back to back from each other. By pushing apart the forks, you can release a part of the ornamental grass to plant. Another way of dividing consists of building a trench around the clump of grass. Pulling up the ornamental grass by jamming a landscaping bar underneath the root system will expose the bottom of the plant in the trench. Gardeners can take a few bunches of grass by cutting through a portion of the bottom with a hacksaw. You should replace the dirt of the main ornamental plant and give it a good dose of water.
  
  

Planting

• Like most plants, ornamental grasses thrive in well-draining soil. Your new planting site should be in a sunny location and be free of other vegetation. You may want to spray the area a few weeks before with a nonselective herbicide to kill off any surrounding vegetation. It is best to set the ornamental grass in its new planting location at the same depth it was planted when it was attached to the main ornamental plant. By keeping the planting hole's soil moist but not saturated, you can help the small clump establish roots. Fertilizing your ornamental plant is rarely recommended. Ornamental plants do not need fertilizer, and rapid growth cannot be supported by the thin stems of the plant.
