Propagation through Stem Cuttings
Propagation through stem cuttings is a common method for Juncus obtusatus Engelm., non Kit. The best time to take stem cuttings is during the summer months when the plant is actively growing. The stem cuttings should be 4-6 inches long and should have at least one node. The lower leaves should be removed, and the cutting should be planted in a well-draining soil that has been pre-moistened. The cuttings should be kept moist and in a location with bright, indirect sunlight until they root and establish in their new location.
Propagation through Seed
Propagation through seed is another option for Juncus obtusatus Engelm., non Kit. The seeds can be planted in a well-draining soil that has been pre-moistened. Germination can take several weeks to occur. It is important to keep the soil moist until the plants establish. Once the plants have grown sufficiently, they can be transplanted into their permanent location. Seed propagation is typically not as common as other methods and is not recommended for home gardeners, as it can be difficult to achieve a high success rate.
