Propagation of Tacazzea venosa Decne. var. martini (Baill.) N.E.Br.
Tacazzea venosa Decne. var. martini (Baill.) N.E.Br. can be propagated by various methods, including:
Seed propagation
The easiest and most common way to propagate Tacazzea venosa Decne. var. martini (Baill.) N.E.Br. is through seed propagation. The seeds are collected from the mature fruits that have turned brown, usually between October and November. Before sowing, the seeds are soaked in water for one day or treated with sulfuric acid for five to ten minutes. The seeds are then sown in seedbeds at a depth of 0.5-1.0 cm and a spacing of 10 cm x 10 cm. Germination usually takes place within two to three weeks after sowing.
Cuttings propagation
Tacazzea venosa Decne. var. martini (Baill.) N.E.Br. can also be propagated through cuttings. Softwood cuttings are collected from the new growth of the plant during the months of June to July. The cuttings should be 10-15 cm long, with a diameter of 0.5-0.7 cm, and should be taken from healthy and disease-free plants. The cuttings are treated with rooting hormone and planted in a rooting medium of sand and peat moss. The cuttings are then kept in a shaded place with high humidity until roots have formed. This method of propagation is less common and may be considered more difficult.
Division propagation
Another way to propagate Tacazzea venosa Decne. var. martini (Baill.) N.E.Br. is through division. This method involves dividing the mature plant into smaller sections and replanting them. Division is usually carried out during the dormant season, which is in the months of November to January. This method is more often used for plants that have become too large or have outgrown their current location. The divisions should have roots and at least one stem or shoot and should be replanted into a well-prepared site with good soil drainage.
