African Jasmine cutting
Sharing with everyone the experience of propagating African Jasmine, the cutting of African Jasmine can certainly bring you help. Let's learn about it together!
African Jasmine has a long blooming period, flowering in winter and summer, with the most brilliant flowers in spring and summer. In the early morning or at dusk, the faint fragrance is refreshing. African Jasmine is an evergreen (climbing) shrub or small tree of the Loganiaceae family, originally from the southern part of our country and Southeast Asia. It can grow up to 5 to 12 meters in gardens. It prefers warm temperatures and sunlight but requires avoiding the intense sunlight of summer; it thrives in environments with high humidity and good ventilation, and is intolerant of cold, dry frost, and sharp drops in temperature. It grows best in loose, fertile, and well-drained soil. It has a strong germination and suckering ability and is particularly tolerant of repeated pruning. The flowering period is May, and the fruiting period is from October to December.
Methods of propagating African Jasmine:
1. Seed sowing:
Collect mature fruits between October and December, remove 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 cold. Alternatively, the seeds can be sand-stored until the seeds crack open before sowing. Seeds sown in late autumn and early winter will only germinate the following spring. After germination, remove the mulch promptly and strengthen water and fertilizer management. In summer, provide shading to expect the cultivation of tall, well-shaped plants.
2. Cutting: Cuttings can be made from the end of April to October, but it is best to do so during the plum rain season from June to July for ideal rooting results. Use 1 to 2-year-old healthy branches as cuttings, 12 to 15 centimeters long with 2 to 3 half leaves, and make the lower cut 0.2 to 0.3 centimeters below the node. Insert them into peat, sandy loam, vermiculite, or yellow heart soil, with peat soil providing the best rooting results. Cover with plastic film to keep moisture and provide shading on sunny days. After 1 to 2 months, they can root, with a survival rate of over 80%.
3. Division: Between March and April, when the plants start to germinate, remove the clump-shaped plants from the pot or dig up the plants from the ground, shake off some of the soil, and cut apart the roots where they are weakly connected with a sharp knife. Ensure each clump has at least 2 to 3 stems and some intact roots, then plant them separately in the ground or in pots. Moreover, many suckers will grow on the roots near the ground, which can be cut from the root with suckers and planted separately, also very simple and convenient.
4. Layering:
① Low layering: In April in southern regions, make a ring-shaped stripping or notch on the lower middle part of 2 to 3-year-old healthy branches at the base, then press them hard into a pre-dug trench in the ground, cover with thick soil, and after about 40 to 50 days, they can root. Between July and August, cut them apart from the mother 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 house at the end of April, make a ring-shaped stripping 0.5 centimeters below the node on 2-year-old healthy branches, with the stripping width about 3 times the thickness of the branch. Then wrap wet mud moss or peat with plastic film around the stripped area, leaving a water inlet at the top of the soil clump, maintaining the moisture of the soil clump, and after 2 to 3 months, they can root. Enthusiasts can use this method to propagate a small number of plants to give to friends.
