Propagation of Ipomoea velutipes Welw. ex Rendle
Propagating Ipomoea velutipes Welw. ex Rendle can be done through various methods which include:
Seed propagation
Seeds of Ipomoea velutipes Welw. ex Rendle can be propagated directly into the soil either in a nursery or in a garden. The seeds should be scarified to break the outer seed coat and then soaked in water for 24 hours before planting to stimulate germination. The seedlings should appear within 14-30 days and can be transplanted after 6-8 weeks of growth.
Cuttings propagation
Stem cuttings can be taken from healthy Ipomoea velutipes Welw. ex Rendle plants and rooted in a moist medium such as sand or perlite. The cuttings should be 8-10 cm long with at least two nodes, and the leaves should be removed from the bottom two nodes. The cuttings should be placed in a partially shaded area and watered regularly until new growth appears. After 2-3 weeks, the cuttings should have developed roots and can be transplanted into pots or the ground.
Division propagation
Ipomoea velutipes Welw. ex Rendle can also be propagated through division of the rhizomes. The root clump should be lifted out of the soil and divided into smaller sections, each containing at least one shoot and some roots. The divided sections can be planted in new pots or the ground, and watered regularly until new growth appears.
Overall, propagating Ipomoea velutipes Welw. ex Rendle using any of the above methods is relatively easy and can be done successfully with proper care and attention.
