Vegetative propagation is an asexual method of reproduction in which plants can grow and reproduce from stems, roots, and leaves. New plants can grow from the detached parts (stems, roots, and leaves) of the old plant because it has sufficient cells to divide and produce a new individual. Cutting and grafting are two different methods of vegetative propagation.


Vegetative propagation is practiced due to the following advantages:

  • Vegetative propagation helps in maintaining the characteristics and features of the parent plant.
  • Cultivation of plants through vegetative propagation consumes less time.
  • Vegetative reproduction helps in bringing the desired characteristics of the plant, such as immunization to diseases through budding and grafting.
  • It helps to develop plant varieties with useful characteristics and is also helpful for plants that rarely produce flowers.
