The seeds should be sown in a well-draining soil mixture and covered lightly with soil. The soil should be kept moist until the seeds germinate, which usually takes 1-2 weeks.
Propagation by cuttings
Propagation by cuttings is another method of propagation that is commonly used for Achyranthes aspera L. var. sicula L. Cuttings should be taken from healthy, mature plants during the growing season. The cuttings should be 4-6 inches long and should have several leaves. The leaves on the lower half of the cutting should be removed, and the cutting should be dipped in rooting hormone before planting. The cuttings should be planted in a well-draining soil mixture and kept moist until roots form, which usually takes 3-4 weeks.
Propagation by division
Propagation by division is a method used to propagate Achyranthes aspera L. var. sicula L. by dividing the plant's clumps. The clumps can be divided in the spring or fall when the plant is not actively growing. The plant should be dug up carefully and divided into smaller sections, each with its own roots. The divided sections should be planted in a well-draining soil mixture and kept moist until they become established.
These methods of propagation can be used to propagate Achyranthes aspera L. var. sicula L. successfully. It is recommended to choose the method that is most suitable for the specific needs of the plant and the grower's capabilities.
