What are the breeding methods and matters needing attention of African jasmine in "Maqian family"? How often is it watered? How to make it blossom?

The original name of African jasmine is Grey, and its alias is carp bile, ash thorn wood, yellow fruit, small yellow fruit, its plump plant shape and green leathery leaves, is a very popular indoor foliage plant in recent years. But how to raise African jasmine? What are the breeding methods and matters needing attention?

African jasmine is native to the evergreen (climbing) shrub or small tree of Loganaceae in southern China and Southeast Asia, formerly known as Cinnamomum officinalis (see Atlas of higher plants in China, Flora of Yunnan, etc.). It is similar to the jasmine of Melilidae only in that the leaves are opposite and the flowers are fragrant. Because the homonym of ash wood is similar to jasmine, and in order to make the name good and easy to sell, the florist gave it a new name "African jasmine". Distributed in southern China and Southeast Asia and other countries.

Culture methods and precautions of African jasmine:

1. [soil] the cultivation of African jasmine in the southern region requires that the planting site should be loose, fertile and well-drained sandy loam. The potted African jasmine in the north can be prepared with 7 parts of rotten leaf soil, 1 part of river sand, 1 part of retted organic fertilizer and 1 part of fermented sawdust. African jasmine can loosen the soil once a month during the growing season, keeping its roots in a good state of penetration. In addition, the soil of potted African jasmine can be changed every 1 to 2 years.

2. [fertilizer] potted African jasmine applied thin mature cake fertilizer and water once a month in the growing season, and phosphorus and potassium fertilizer once before flowering in May to promote plant flowering, and added phosphate and potassium fertilizer 1 or 2 times after autumn to pass the winter safely. Potted plants in northern China, in order to prevent leaf yellowing, 0.2% ferrous sulfate was added during the growing season. When planting in the ground, it is necessary to apply sufficient base fertilizer, and at the end of autumn, cake fertilizer is applied in trenches outside the root system, 0.5 to 1 kg per plant.

3. [temperature] African jasmine grows well in a warm climate, and the optimum growth temperature is 18 ℃ to 32 ℃. When the summer temperature is higher than 38 ℃, it will inhibit plant growth. Some areas of South China can survive the winter in the open field, while pot cultivation in the north of the Yangtze River requires that the greenhouse temperature is not lower than 3 ℃ to 5 ℃ in winter.

4. [light] African jasmine likes the sun, and the primary environment is mostly in a semi-shaded state. South China is planted as garden greening trees, and it is best to choose a place with side shade; potted plants in the north of the Yangtze River can receive full light in spring and autumn, and in summer, it is required to build a shed for shade, or move it under the shade of big trees, at least to avoid direct sunlight for several hours before and after noon. It is particularly noteworthy that the temperature rose sharply and the light was very strong on a sunny day after a long rain from June to July. Shading must be done to prevent young shoots and leaves from being burned. Potted African jasmine in public places requires sufficient scattered light, or placed near the window, should not be too dark, otherwise it will cause the leaves to lose green and yellowing or fall off.

5. [moisture] African jasmine, whether planted in the ground or potted, requires sufficient water, but the roots must not accumulate water, otherwise they are easy to rot. Watering in spring and autumn to keep the basin soil moist; beware of stagnant water in plum rain season; in hot summer, spray water once in the morning and afternoon to humidify and cool; for indoor potted African jasmine in winter, it is appropriate to keep the basin soil slightly tide. and spray water to the leaves when the temperature is relatively high around noon. In spring, summer and autumn, under the condition of normal fertilization, if the lower leaves of potted African jasmine turn yellow and fall off, it is likely to be due to stagnant water and rotten roots, so it is necessary to turn the basin and change the soil in time; in summer, if you are negligent in watering, when the newly drawn tender shoots wilt and droop, you can not immediately water the basin soil, but spray some water to the leaves first, and then pour appropriate amount of water to the basin soil after the leaves have recovered a little.

Note: if the home-raised African jasmine is just purchased from the south in autumn and winter, you should do a good job of cold prevention in winter. When the strong cold air in the north goes south and the temperature drops greatly, the electric furnace, heater and coal stove should be used in the greenhouse to ensure that the temperature in the greenhouse is not lower than 5 ℃, otherwise it will be difficult for the frozen plants to resume growth in a short time in the second year. For a small number of potted plants left in the office or room, in addition to adding a set of double-layer plastic film bags, the air conditioner or heater can be turned on at night and must not be taken lightly.

When does African jasmine blossom?

The florescence of African jasmine is from May to June, with terminal flowers and white or yellow-white Corolla. Inflorescences erect terminal, with 1 to 3 flowers, with very short total pedicels, Corolla white, funnel-shaped, fragrant, upper 5-lobed, the whole Corolla trumpet-shaped. However, the flowering age of African jasmine is longer, from 5 years to more than ten years, so it is difficult for ordinary flower friends to last until the moment of flowering.

How to make African jasmine blossom?

African jasmine needs adequate phosphorus and potassium fertilizer during its growth, but people tend to focus on nitrogen fertilizer when applying fertilizer. Indeed, nitrogen fertilizer can grow leaves, keep the leaves fresh green, and hinder the differentiation of flower buds.

For this reason, in the growing season of jasmine, especially in the bud period, it is necessary to apply less nitrogen fertilizer and more phosphorus and potassium fertilizer. In addition to using rotten bone powder and poultry manure as base fertilizer, bone and poultry manure rotting leachate or available phosphorus and potassium fertilizer can also be used as topdressing. African jasmine is a light-loving plant, the balcony in the family can not receive light all day, the plant will be shaded for a long time, resulting in large and sparse leaves, which lengthens the flowering life to a certain extent. So if you want to blossom, you should move the plant to the sun as much as possible. If you live in a building, it is inconvenient to operate, and you are afraid of exposure to the sun. You can move outside every weekend and receive 3-4 hours of direct sunlight. If your African jasmine has been raised for 3 or 4 years, increase the light and it may blossom in the fifth year.
