Propagation of Strophanthus klainei De Wild.
Strophanthus klainei De Wild. can be propagated by seeds or stem cuttings.
Propagation by Seeds
Seeds of the plant should be collected when the capsules turn brown and split open. The seeds should be cleaned and dried in the shade for a few days. Stratification of the seeds in moist sand at a temperature of 4°C can enhance germination. The seeds can also be directly sown in the field or in pots with well-drained soil. Germination takes two to six weeks. Young plants should be watered regularly and protected from direct sunlight.
Propagation by Stem Cuttings
Stem cuttings of Strophanthus klainei De Wild. can be taken from young healthy plants. Cuttings about 10-15 cm long should be treated with a rooting hormone and inserted into a well-drained substrate. A mix of sand and peat is suitable. Cuttings should be kept in a humid chamber for about a month until roots develop. Once the new plant has firmly established roots, it can be transplanted to the desired site.
