Propagation of Tabernaemontana longiflora Benth.
The Tabernaemontana longiflora Benth. plant can be multiplied using different propagation methods such as seeds, cuttings, and layering.
Propagation by Seeds:
Seeds of Tabernaemontana longiflora Benth. can be collected and sown in well-prepared seed beds or containers. Seeds are extracted from the plant pods and dried in the shade for a few days. Sowing should be done during the rainy season. Seeds should be sown no deeper than their diameter. Germination occurs within 2-3 weeks.
Propagation by Cuttings:
