A detailed guide to African jasmine propagation methods, easily learn propagation techniques

Cutting propagation

1. Timing

The cutting time should be chosen from April to October, but it is best in June-July, when rainfall is more abundant and rooting is faster.

2. Substrate

The most common is soil culture, and the substrate is best acidic fertile soil, preferably made from peat soil, sandy loam, vermiculite or yellow subsoil.

3. Cuttings

Making cuttings is a key part of cutting propagation. Take relatively robust growing branches, cut off a section, then cut them into 12-15 cm pieces, so that each cutting has 2-3 leaves, cut off all the remaining leaves, and make the cut position best located 0.3 cm below a node.

4. Cutting

Insert the prepared cuttings into the prepared substrate, then cover with plastic film to retain moisture, place them in a shady place for care, and do not let direct sunlight hit them.

Seed propagation

1. Timing

Generally, African jasmine fruit ripens in July, so seeds are usually collected from October to December. After collecting the mature fruit, remove the seeds and store them in sand.

2. Soaking

Take out the seeds and soak them in warm water for 5 minutes, evenly scatter them on a sandy loam seedbed, cover with soil at a thickness of 2-3 cm, and add rice straw or plastic film for warmth.

3. Care

During the care period, keep the soil moist. Generally, seedlings emerge only in the spring of the following year. After emergence, promptly remove the rice straw or plastic film, then strengthen fertilizer and water management, and pay attention to proper shading so the plants can grow healthily.

Division propagation

1. Timing

Division is the simplest propagation method for African jasmine, and its timing is generally chosen in March-April.

2. Division

Remove the whole African jasmine plant together with the soil from the flower pot, use a tool to cut it apart from the base fertilizer where the root system connection is relatively weak, divide the plant into several clumps, keep 2-3 stems per clump, and ensure the root system is not damaged, then plant them separately.

3. Care

After division, water once, making sure to water thoroughly, keep the soil moist, and place it in a shady spot. Generally, no fertilizing is needed during care, and normal growth can resume after about half a month.

Layering propagation

1. Timing

Generally chosen in April.

2. Layering

Dig a trench in the potting soil, then choose a robust branch at the base of the African jasmine, perform ring barking on the middle-lower part of the branch, then press the separated part and bury it into the dug trench, and cover with sandy soil.

3. Management

Generally it will root after one month, but wait until July-August, then separate it from the mother plant and transplant it elsewhere. During the layering process, also pay attention to proper shading.

How to grow African jasmine

1. Soil

The soil requirements for growing African jasmine differ between the south and the north: in the southern region, the planting site should be loose, fertile, well-drained sandy loam. For potted African jasmine in the north, it can be prepared with more leaf mold, river sand, composted organic fertilizer, and fermented sawdust. During the growth period, loosen the soil every month to keep the roots well aerated. Potted African jasmine can have its soil changed once every 1 year.

2. Temperature

African jasmine likes a warm environment, and the suitable growth temperature is 18°C-32°C. If the summer temperature is above 38°C, it will inhibit plant growth; in some parts of South China, ground planting can overwinter outdoors, while potted plants north of the Yangtze River require a winter greenhouse temperature of no less than 3°C to 5°C.

3. Light

African jasmine likes sunlight. In South China, when planted in the ground as a garden greening tree, it is best in a shaded place; for potted plants north of the Yangtze River, full sunlight can be accepted in spring and autumn, while in summer shading treatment is needed, or place it under a large tree, avoiding direct sunlight; for potted plants in public places, relatively sufficient scattered light is required, or place them near a window, and they should not be too dark, otherwise the leaves will lose green and turn yellow or fall off.

4. Water

Potted African jasmine needs sufficient water, but the roots must not accumulate water, otherwise root rot is easy. In spring and autumn, water to keep the potting soil moist; in summer, spray water once in the morning and once in the afternoon to increase humidity and lower temperature; in winter, for indoor potted African jasmine, keep the potting soil slightly moist, and spray an appropriate amount of water on the leaf surface around noon when the temperature is relatively higher.

5. Fertilizing

During the vigorous growth period, potted African jasmine should be given a topdressing of thin decomposed cake fertilizer water once a month. Before flowering in May, apply a phosphorus-potassium fertilizer once to promote flowering. After entering autumn, apply topdressing 1-2 times to supplement phosphorus and potassium for better overwintering. For potted plants in the northern region, to avoid yellowing leaves, add 0.2% ferrous sulfate when watering and fertilizing during the growing season to keep the leaves verdant.
