It is important to use clean and sharp pruning tools to avoid damaging the plant. Deadheading can also be done to encourage new flower growth and prevent the plant from producing seeds.

Propagation of Arthraxon lanceolatus (Roxb.) Hochst. var. puberulus (Chiov.) Mattei

Arthraxon lanceolatus (Roxb.) Hochst. var. puberulus (Chiov.) Mattei, commonly known as hairy whisper grass or lanceleaf whisper grass, can be propagated from seeds, root division, and stem cuttings.

Propagation from Seeds

Seeds of Arthraxon lanceolatus (Roxb.) Hochst. var. puberulus (Chiov.) Mattei can be collected from the matured inflorescence in autumn, cleaned, dried, and stored in cool and dry conditions until spring. In spring, the seeds can be planted directly in well-drained soil. The soil should be kept moist until the seeds germinate, which takes about 7 to 21 days. The seedlings can be transplanted to their desired location once they reach the size of 3 to 4 inches.

Propagation from Root Division

Root division is a common propagation method used for Arthraxon lanceolatus (Roxb.) Hochst. var. puberulus (Chiov.) Mattei. It can be done in early spring when the plant starts to grow again. The clump can be dug up, and its roots can be divided into smaller sections. Each section should have a minimum of one shoot and a well-developed root system. The divided sections can be planted in separate pots or directly in the soil. Water the plant regularly and provide adequate sunlight to help them establish well.

Propagation from Stem Cuttings

Propagation from stem cuttings is a relatively easy and quick method for Arthraxon lanceolatus (Roxb.) Hochst. var. puberulus (Chiov.) Mattei. It can be done at any time during the growing season, but it is most successful in early spring or late summer. Select a healthy stem and cut it just below a node. Remove the leaves from the bottom half of the stem and dip it in rooting hormone. Plant the stem cutting in moist soil and cover with a plastic bag to maintain humidity. Place the pot in a warm and bright location, avoiding direct sunlight. Water the cutting when the topsoil feels dry, but make sure not to overwater it. The cutting will root in about 4 to 6 weeks and can be transplanted to its desired location once it has established well.
