Propagation of Colubrina L.C. Rich. ex Brongn.
Colubrina L.C. Rich. ex Brongn. is a plant that can be propagated through various methods. The plant can be propagated through seeds and vegetative cuttings.
Propagation through Seeds
The plant produces fruits that contain seeds. Seeds can be collected from the matured fruit, washed, dried, and then sown in well-draining, fertile soil.

The cutting should be treated with hormone rooting powder and planted in hormone treated soil. The cutting should be kept moist and warm, and roots should develop in three to five weeks. Once the roots have formed, the cutting can be transplanted to its permanent location.
