Cuttings Propagation
Stachytarpheta urticifolia Sims can also be propagated by vegetative cuttings. Cuttings should be collected from the stem of the plant during the growing season. The cuttings should be at least 6 inches long and have 2-3 nodes. The lower leaves should be removed, and the cuttings should be dipped in a rooting hormone to enhance root formation. The cuttings should be planted in a well-draining soil mix and kept moist. The cuttings will root in 2-3 weeks.
Division Propagation
Another method of propagation is through division. This can be done during the growing season. The plant should be carefully dug up, and the roots should be separated into two or more divisions. Each division should have some roots and shoots. The divisions should be planted in a well-draining soil mix and kept moist until they are established.
In conclusion, Stachytarpheta urticifolia Sims can be easily propagated through seeds, cuttings, and division. Depending on the preference of the gardener, the most suitable method can be selected to propagate the plant.
