Regular pruning of this species of Heterotis angolensis helps to promote healthy growth, increase yield, and prevent the plant from becoming too bushy or overcrowded.
Propagation of Heterotis angolensis (Cogn.) Jacq.-Fél. var. bambutorum (Gilg & Ledermann ex Engl.) Jacq.-Fél.
Heterotis angolensis (Cogn.) Jacq.-Fél. var. bambutorum (Gilg & Ledermann ex Engl.) Jacq.-Fél. can be propagated through various methods, including seeds, cuttings, and division of rhizomes.
Propagation through seeds
Seeds of Heterotis angolensis (Cogn.) Jacq.-Fél. var. bambutorum (Gilg & Ledermann ex Engl.) Jacq.-Fél. can be sown directly into the soil or in pots. The seeds should be sown in a suitable potting mix that is well-draining and rich in organic matter. The soil should be kept moist, but not waterlogged. The seeds usually take around 2 to 3 weeks to germinate. Once the seedlings have grown to a reasonable size, they can be transplanted into their permanent location.
Propagation through cuttings
Heterotis angolensis (Cogn.) Jacq.-Fél. var. bambutorum (Gilg & Ledermann ex Engl.) Jacq.-Fél. can also be propagated through stem cuttings. The cuttings should be taken from mature plants during the growing season. The cuttings should be around 4 to 6 inches in length and should have at least 2 to 3 nodes. The cuttings should be dipped into rooting hormone and then planted in a well-draining potting mix. The soil should be kept moist, but not waterlogged. The cuttings usually take around 4 to 6 weeks to develop roots. Once the roots have formed, the plant can be transplanted into its permanent location.
Propagation through division of rhizomes
Heterotis angolensis (Cogn.) Jacq.-Fél. var. bambutorum (Gilg & Ledermann ex Engl.) Jacq.-Fél. can also be propagated through division of rhizomes. This method is usually done during the dormant season. The parent plant should be dug out carefully, and the rhizomes should be divided into sections. Each section should have a healthy shoot and a portion of the rhizome. The sections should be replanted into their permanent location, ensuring that the soil is well-draining and rich in organic matter. The newly planted sections should be kept moist, but not waterlogged, until they have established themselves in their new location.
