How to Divide Miscanthus
Perennial miscanthus grass provides an attractive addition to the landscape. The fountain-like growth habit is green through spring and summer. The brown foliage remains ornamental through the fall months and into winter. Miscanthus grows from a swollen root storage system called a rhizome. The rhizome pieces can each grow into a new plant if divided properly. Miscanthus tolerates division once every two years. Does this Spark an idea?

1
Dig up the rhizomes in spring after the new growth begins. Loosen the soil around the base of the plant with a trowel, then lift the entire rhizome from the ground.
-
2
Cut the rhizome into 4- to 6-inch-long pieces, using a clean knife. Cut each piece so it contains at least two nodes or stems.

Plant each rhizome piece into a prepared well-drained bed that receives full sunlight. Set the rhizome so the top is 4 inches below the soil surface. Space the plants 2 to 3 feet apart in all directions.
-
4
Water the bed thoroughly after replanting to settle the soil and collapse any air pockets around the rhizomes. Wet the soil to a 6-inch depth.
-
5
Water the miscanthus one to two times a week so the soil remains moist and doesn't dry out completely while the rhizomes are establishing. A 2-inch layer of mulch helps retain moisture and protects the rhizomes from spring temperature fluctuations.
