Propagation of Pennisetum pedicellatum Trin.
Pennisetum pedicellatum Trin., also known as long pedicelled fountain grass, is a warm-season perennial grass that is native to Africa. It is commonly used for erosion control, soil stabilization, and as a forage crop for grazing animals. Propagation of this plant can be done through various methods:
Seed Propagation
One of the most popular ways to propagate Pennisetum pedicellatum is by seed propagation. The seeds of this plant can be obtained from mature plants or from plant nurseries. The seeds should be sown in well-drained soil in early spring or summer, and should be covered lightly with soil. Water the soil regularly until germination, which usually takes 7-21 days. The young seedlings should be transplanted into individual pots or into the ground once they reach 4-5 inches tall.
Division
Division is another propagation method that can be used for Pennisetum pedicellatum. The plant should be divided in the spring, just before the growing season begins. First, dig up the plant carefully, making sure to damage the roots as little as possible. Then, divide the root ball into several sections, each with a healthy number of roots and shoots. These sections can be planted directly into the soil or into pots.
Cutting Propagation
Cutting propagation of Pennisetum pedicellatum is also possible. Take softwood cuttings from new growth in the spring or summer. Dip the ends of the cuttings in rooting hormone, and plant them in a well-drained potting mix. Water the cuttings regularly, and keep them in a warm, humid place until they root. Once they have rooted, the cuttings can be transplanted into pots or the ground.
