Propagation of Gomphocarpus hastatus E.Mey. var. angustifolius Meisn.
Gomphocarpus hastatus E.Mey. var. angustifolius Meisn. can be propagated through seeds, cuttings, and division.
Propagation through seeds
Seeds of Gomphocarpus hastatus E.Mey. var. angustifolius Meisn. can be collected from the pods when they turn brown and start to open. The seeds must be sown right after collection in trays filled with well-draining soil mixed with compost. The trays should be kept moist and placed in a partially shaded spot until the seeds germinate, which usually takes around 14-21 days. Once the seedlings have developed a few sets of true leaves, they can be transplanted into individual pots or directly into a garden bed.
Propagation through cuttings
Gomphocarpus hastatus E.Mey. var. angustifolius Meisn. can be propagated through stem cuttings taken during the growing season. Cuttings should be around 10-15 cm long and taken from healthy, disease-free plants. The lower leaves should be removed, and the cuttings should be dipped in rooting hormone powder before planting them in well-draining soil mixed with perlite. The cuttings should be kept moist and placed in a partially shaded spot until they develop roots, which usually takes around 3-4 weeks. Once the cuttings have rooted, they can be transplanted into individual pots or directly into a garden bed.
Propagation through division
Gomphocarpus hastatus E.Mey. var. angustifolius Meisn. can also be propagated through division, although this method is not commonly used. The plant can be gently dug out of the garden bed, and the root ball can be divided into smaller sections, making sure that each section has a few healthy shoots. The divided plants can be planted in individual pots or directly into a garden bed, and they should be watered regularly until they establish themselves.
