Seed propagation
Bignonia adenophylla Wall. ex G.Don can be propagated from seeds, which are easily available from nurseries. The seeds need to be soaked in water for 24 hours and then sown in good quality potting soil. The seeds should be covered with a thin layer of soil and should be kept in a warm and humid place. The soil should be kept moist, and the seeds should germinate within 3-4 weeks. Once the plants reach a size of 15-20 cm, they can be transplanted into individual pots or planted into the ground.
Vegetative propagation
Bignonia adenophylla Wall. ex G.Don can be propagated from cuttings or layering.
Cuttings: Cuttings of the plant should be taken in spring or early summer. The cuttings should be taken from the softwood of the plant and should be 12-15 cm long. The lower leaves should be removed, and the cuttings should be dipped in a rooting hormone and planted in a well-draining soil mix. The cuttings should be kept in a warm and humid place and should be watered regularly. The cuttings should root within 2-3 weeks, and once they grow to 15-20 cm, they can be transplanted into individual pots or planted into the ground.
Layering: Layering is another method of vegetative propagation. In this method, a low-lying branch of the plant is bent down to the ground and covered with soil. The branch should be wounded using a knife or a sharp blade to encourage root development. After a few weeks, the branch should have developed roots, and it can be separated from the mother plant, transplanted into individual pots or planted into the ground.
Propagation of Bignonia adenophylla Wall. ex G.Don using any of the above methods is easy and can be done at home with a little knowledge and effort.
