It is valued for its fine, curly leaves and ability to grow in a variety of soil types and conditions. Propagation of Arthratherum subacaule Nees is relatively straightforward, and the plant can be propagated by seed, division, and cuttings.
Propagation by Seed
Arthratherum subacaule Nees produces small, brown seed heads in late summer or fall. These seed heads can be collected and dried in a warm, well-ventilated location. Once the seeds are dry, they can be planted in pots or directly in the ground. The seeds should be planted shallowly and covered with a thin layer of soil. Keep the soil moist but not waterlogged, and the seeds should germinate within 2-3 weeks.
Propagation by Division
To propagate Arthratherum subacaule Nees by division, dig up an established clump of plants in early spring or fall. Use a sharp, clean knife or shovel to divide the clump into smaller sections. Each section should have several healthy roots and shoots. Replant the sections immediately in a location with well-draining soil and full to partial sunlight. Water the newly divided plants regularly until they are established.
Propagation by Cuttings
Arthratherum subacaule Nees can also be propagated by taking stem cuttings in the spring or summer. Cut a 3-4 inch section of stem from the parent plant, making sure the cutting has at least one node. Remove any leaves from the lower two-thirds of the cutting and dip the cut end in rooting hormone. Insert the cutting in a container filled with moist potting soil. Cover the container with a plastic bag to maintain high humidity and place it in a location with bright, indirect light. Once roots have formed, transplant the new plant into a pot or directly in the ground.
