You can also trim the plant to the desired height and shape. Pruning stimulates new growth and promotes better blooming.
Propagation methods for Jasminum fluminense Vell. subsp. nairobiense Turrill
Jasminum fluminense Vell. subsp. nairobiense Turrill, commonly known as river jasmine, is a fast-growing evergreen climber that produces fragrant yellow flowers. It is a beautiful plant and can be propagated through various methods such as:
Seeds
Propagation through seeds is one of the easiest and most common methods. Collect ripe seeds in summer or autumn and store them in a cool, dry place. Soak the seeds overnight in water before planting to break the dormancy. Sow the seeds in well-drained soil and keep them moist. Germination will take place within 1-2 weeks and the seedlings can be transplanted once they reach a height of 10-15 cm.
Cuttings
Cutting propagation is a reliable method for obtaining clones of the parent plant. Take cuttings in the spring or summer, when the plant is actively growing. Use a sharp, sterilized knife to take cuttings of 10-15 cm in length. Remove the lower leaves and dip the cut end in a rooting hormone. Plant the cutting in well-drained soil and cover it with a plastic bag to maintain humidity. Keep the soil moist and place the cutting in a warm, bright area, but out of direct sunlight. Rooting should occur within 3-4 weeks and the newly rooted plant can be transplanted to a bigger pot or the ground.
Air layering
This propagation method involves creating a new plant while the parent plant is still growing. Take a healthy stem and remove a ring of bark from the middle of the stem, about 10-15 cm from the tip. Apply a rooting hormone to the exposed area and wrap it with moist sphagnum moss. Cover the moss with a plastic sheet and seal the ends tightly. Keep the moss moist and roots will emerge from the exposed area. Once the roots are 5-10 cm in length, cut the stem below the rooted area and plant it in well-drained soil. Keep the soil moist until the plant establishes itself.
These are the most common propagation methods for Jasminum fluminense Vell. subsp. nairobiense Turrill. Choose a method that works best for you and enjoy growing this beautiful plant!
