How to propagate Chinese violet? Detailed introduction to two propagation methods
Chinese violet is a shrub or small tree, evergreen all year round, with a full plant shape. It is an excellent courtyard flower variety, and now flower enthusiasts often grow Chinese violet as potted plants. Artificial propagation of Chinese violet can use cutting and division methods. The editor will briefly introduce them for you.
Chinese violet
I. Cuttings
Chinese violet can be propagated by cuttings, sowing, layering, or division, but in the north cuttings are mainly used. In July to August, take current-year branches, cut them into 8-10 cm sections as cuttings, retain 3-4 top leaves, insert them into clean river sand, and place them in a greenhouse. They can root in 40-60 days, with a survival rate of over 85%.
II. Division
Between March and April, when the plant just begins to sprout, remove the clustered plant from the flower pot, or dig up the clustered ground-planted plant from the soil, shake off part of the old soil, and at the weak connection point of the root system, cut it apart with a sharp knife, so that each clump has at least 2 to 3 stems and part of intact roots, and plant them separately in the ground or in pots. In addition, many suckers will grow on its roots near the ground. They can be cut off from the roots together with the suckers and planted separately.
How to grow Chinese violet. Main value of Chinese violet
Chinese violet has large flowers with a rich fragrance, luxuriant branches and leaves, and a beautiful tree shape. It is an excellent courtyard and indoor foliage plant. So how do you grow Chinese violet? What value does it have? Let us learn about it together next.
I. How to grow Chinese violet
1. Soil: Choose loose, fertile, well-drained sandy loam for cultivation. For potted plants in the north, you can use a mix of 7 parts leaf mold, 1 part river sand, 1 part composted organic fertilizer, and 1 part fermented sawdust. During the growing season, loosen the soil of potted plants once a month, and always keep the root area in a well-aerated state.
2. Temperature: Choose a warm climate environment. The suitable growth temperature for Chinese violet is 18-32°C. When the summer temperature is above 38°C, plant growth will be inhibited; in some areas of South China, ground planting can overwinter outdoors, while potted plants north of the Yangtze River require the winter greenhouse temperature to be no lower than 5°C.
3. Light: Choose a location with ample sunlight but with some shading conditions. In spring and autumn, full sunlight can be accepted. In summer, it is necessary to set up shade or move it under the dense shade of large trees, at least avoiding direct sunlight for several hours around noon; it is especially worth noting that in June-July, after long rainy periods, when a big sunny day occurs, the temperature rises suddenly and the light is very strong, so shading work must be done well to prevent young new shoots and tender leaves from being sunburned.
4. Water: In spring and autumn, water just enough to keep the potting soil moist. In rainy seasons, strictly prevent water accumulation. In the hot summer with strong sunlight, spray water once in the morning and once in the afternoon to increase humidity and lower temperature. In winter, for indoor potted plants, it is appropriate to keep the potting soil slightly moist, and around noon when the temperature is relatively higher, spray an appropriate amount of water on the leaves.
5. Fertilizing: During the growing season, apply once a month a thin, fully decomposed cake fertilizer solution to potted plants. Before flowering in May, apply a phosphorus-potassium fertilizer once to promote flowering. After autumn, apply additional phosphorus-potassium fertilizer 1-2 times to help it overwinter safely. For potted plants in northern regions, to prevent leaf yellowing, add 0.2 ferrous sulfate when watering and fertilizing during the growing season.
6. Pruning: Chinese violet has relatively strong sprouting and suckering ability and is very tolerant of pruning. During the growing period, it can be pruned into any shape at will, usually into a spherical, platform, or fan shape. To maintain a beautiful tree shape, suckering buds at the base of the plant should be cut off in time to avoid consuming too many nutrients from the plant.
II. Main value of Chinese violet
1. Horticultural value: Chinese violet has large flowers, is fragrant, stays green all year round, grows well, has luxuriant branches and leaves, a beautiful tree shape, nearly fleshy leaves, and dark green glossy leaf color. It is an excellent courtyard and indoor foliage plant.
2. Landscaping value: It has strong pollution resistance and is suitable for greening in road median strips, main traffic roads, forest belts, and landscape nodes.
The above isHow to grow Chinese violetand an introduction to the value of Chinese violet. Chinese violet can produce volatile oils that have a significant bactericidal effect, so it is very suitable for growing indoors.

Chinese violet is also called African jasmine. It belongs to the Loganiaceae family and the genus Fagraea. Its full plant shape plus its green leathery leaves make it very pleasing, and it is a popular indoor foliage plant in recent years. After several years of cultivation, it has been found that when the ambient temperature is 20°C to 30°C, roots can be dug from plants in vigorous growth stage, cut into sections, and used for cutting propagation of seedlings. The specific method is as follows:Use leaf mold or fine river sand mixed with a small amount of phosphorus-potassium compound fertilizer and with good water permeability and air permeability as the substrate. In a greenhouse, choose a well-lit place to make a small arch shed. For household root cuttings, a small sunny seedbed can be made in a sunny place, and for a small number, a deep pot covered with film can also be used instead. Spread the substrate evenly in the small arch shed (small sunny seedbed, deep pot), with a depth of not less than 20 cm. In combination with repotting, choose a mother plant with good rooting and no pests or diseases. Carefully remove part of the old soil, dig out roots 0.3 cm to 2 cm thick, and cut root segments 6 cm to 10 cm long with a flat upper cut and a slanted lower cut as seed roots (the amount dug must not exceed one third, otherwise the mother plant will shed leaves severely). If they cannot be inserted immediately after cutting, they need to be tied up and stored in a cool, moist place. Never expose them to wind and sun, so as to avoid excessive water loss. To improve the rooting rate, prepare a 1000 ppm ABT No. 1 rooting powder solution, soak the seed roots for 5 hours, and then insert them upright with the thicker end facing up. If the roots are thin and soft, first make holes in the ground with a small wooden stick and then insert them. After insertion, cover with the culture substrate, preferably so that after watering the top of the root end is level with the ground. Apply 3% carbofuran granules at 15 g/sq m to 30 g/sq m, evenly irrigate with 500 times solution of 95% dichlorvos soluble powder or 2000 times solution of 50% methyl thiophanate wettable powder, then seal with transparent plastic film. After that, spray once a week with 500 times solution of 95% dichlorvos soluble powder, and note that the surface of the cutting bed should always be kept moist. Ventilate when the temperature exceeds 35°C. Normally, roots and sprouts will form in about 45 days. After that, spray 0.3 urea water and 0.3% potassium dihydrogen phosphate solution once or twice a week. When it grows to 10 cm, pinch off the top to promote side growth. When it grows to 15 cm to 20 cm, transplant it into a pot for cultivation, strengthen management, and in the same year a small beautiful Chinese violet can be formed.
