African Jasmine Propagation Methods
A comprehensive guide to the propagation of African Jasmine, covering the planting process, propagation methods, and details as follows:
There are many propagation methods for African Jasmine, including seeding, cutting, layering, and division.
African Jasmine Seeding
Collect mature fruits between October and December, extract the seeds, and broadcast or drill them into a loose and fertile sandy loam seedbed. Cover the seeds with 2 to 3 centimeters of soil and mulch with straw or plastic film to keep warm and prevent frost. Alternatively, store the seeds in sand until the seeds crack and show white before sowing. Seeds sown at the end of autumn and beginning of winter will not germinate until the following spring. Remove the mulch after germination and strengthen water and fertilizer management; after summer begins, provide shade to expect the cultivation of tall, well-shaped plants.
African Jasmine Cutting
Propagation by cuttings can be carried out from late April to October, but it is best to do so during the plum rain season from June to July for ideal rooting results. Use healthy branches 1 to 2 years old, 12 to 15 centimeters long, with 2 to 3 half leaves, and make the lower cut just below the node at 0.2 to 0.3 centimeters. Plant the cuttings in peat, sandy loam, vermiculite, or yellow heart soil, with peat providing the best rooting results. Cover with plastic film to retain moisture, and provide shade during sunny weather. Roots can form in 1 to 2 months, with a survival rate of over 80%.
African Jasmine Division
Between March and April, when the plants begin to sprout, remove the clump from the pot or dig up the ground plant, shake off some of the soil, and cut the plant where the roots are weakly connected with a sharp knife, ensuring each clump has at least 2 to 3 stems and some intact roots. Plant them separately in the ground or in pots. Additionally, many suckers will grow on the roots near the ground, which can be cut from the root and planted separately, a very simple and convenient method.
African Jasmine Layering
① Low layering, in southern regions during April, strip the bark or make an incision on the middle to lower part of 2 to 3-year-old healthy branches at the base, then press and bury them in pre-dug trenches in the ground. Cover with thick soil, and after about 40 to 50 days, roots will form. Between July and August, separate the rooted branches from the parent plant and plant them separately in the ground or in pots. This method is commonly used in production.
② High layering, for potted plants in northern regions after moving out of the greenhouse in late April, strip the bark 0.5 centimeters below the node on 2-year-old healthy branches, with the width of the strip being about three times the diameter of the branch. Wrap wet mud or peat moss in plastic film around the stripped area, leaving an opening for water at the top of the soil clump. Keep the soil clump moist, and roots will form in 2 to 3 months. Enthusiasts can use this method to propagate a small number of plants to gift to friends.
Management Tips
African Jasmine grows well in warm climates, with an optimal growth temperature of 18°C to 32°C. When summer temperatures exceed 38°C, growth is suppressed. In some parts of South China, it can overwinter outdoors, while in areas north of the Yangtze River, potted plants require a greenhouse temperature of no lower than 3°C to 5°C in winter.
