Division Propagation
Propagation of Tephrosia secunda can also be done through division. Mature plants can be dug up and divided into several smaller plants. It is essential to ensure that each plant section has enough roots to support its growth. These sections can be planted directly into the field or in pots with a suitable potting mix.
In conclusion, there are various methods to propagate Tephrosia secunda, including seed propagation, cutting propagation and division. These methods are easy and require minimal resources and skills. Successful propagation of Tephrosia secunda guarantees a steady and continuous supply of the plant for use in agriculture and medicine.
