I like the environment with high air humidity and good ventilation, and I am not resistant to cold, dry freezing and sudden drop of temperature.
The medium is fertile, well-drained loam or sandy loam, which keeps good ventilation, can avoid pests and diseases, and likes high temperature.
Whether planted in the ground or potted, you need enough water, but the roots must not accumulate water, otherwise the roots will rot easily.
Fertilization should be diligent and thin, and more organic liquid fertilizer should be applied.
Water in spring and autumn to keep the soil moist; Beware of water accumulation in rainy season; In hot summer, spray water once in the morning and evening to humidify and cool down; When potted indoors in winter, it is advisable to keep the soil slightly moist. When the temperature is relatively high around noon, spray appropriate amount of water on the leaves.
Autumn needs good light and sufficient fertilizer.
Sufficient sunshine must be given in winter, and the temperature should be kept at about 65438 05℃, and it can be increased to about 25℃ with the increase of temperature in spring.
Question 2: How does African jasmine blossom? Now that the African jasmine season has passed, we can only wait for next year. In April next year, bury 30 high-phosphorus and potassium compound fertilizers in the pot, because phosphorus can promote the formation of flower buds and make them more suitable for flowering, and potassium can make flower branches strong and flowers long and long. Usually keep the pot soil dry and wet, so that more flower buds can be formed. If it is planted indoors, it is better to keep it in the sun for two days in the morning and evening 1-2 hours. Usually placed in a sunny and ventilated place indoors.
Question 3: How to make African jasmine blossom? can
Question 4: How to make African jasmine grow faster? The growth environment of African jasmine should be adapted to local conditions. For example, planting in temperate regions of South China can safely overwinter without special care; However, if the winter climate north of the Yangtze River is cold and the temperature difference between day and night is large, potted plants should be planted in the greenhouse, and the temperature should not be lower than 3~5℃, and the lowest temperature should not be lower than 0℃, otherwise their leaves will be easily frozen.
As for soil, African jasmine likes fertile soil with good air permeability, so it grows best on loose and fertile loam with good drainage. The soil can be made of 7 parts humus, 1 part river sand, 1 part retting organic fertilizer and 1 part fermented sawdust.
Whether potted or planted, you need enough water. The soil in the basin should be kept slightly wet in spring, autumn and winter, and easy to dry in summer, so it can be sprayed once in the morning and evening. In the rainy season in the middle and lower reaches of the Yangtze River, it is necessary to guard against the erosion of roots by water in the basin. African jasmine grows fast and is relatively resistant to shearing, so it can be pruned according to personal preference without worrying about affecting its growth.
According to the above methods, African jasmine can grow well and quickly.
Question 5: How often and when do African jasmine flowers bloom? African jasmine needs to grow very big to blossom. Corolla diameter should be greater than 1 m. Once it blooms, it will bloom in late spring and early summer every year. These flowers are white and fragrant.
Question 6: How can African jasmine flower in plain? Put it in a bright and ventilated place on the balcony to increase the light intensity, add some nutrient solution every time you water it, and often spray potassium dihydrogen phosphate on the leaves to promote the flowering of plants.
Question 7: How to prune African jasmine? African jasmine is usually pruned during the growing period so as not to affect the viewing. If the lower blade falls off seriously, it must be cut again. The specific method is: put the plants in suitable environmental conditions about half a month in advance (such as in sunny places in spring or in scattered places in summer), and apply appropriate amount of hot farming net fertilizer to promote growth. When the growth is normal after half a month, each branch should be cut short, and the position of cutting short depends on the size of the plant. Generally, the interception length is about 15 cm, and it can be kept to 30 cm, so it should be flexible. After pruning, the watering times can be controlled. Due to the decrease or disappearance of leaves, transpiration is extremely low and water demand is not great. However, in the future, it is best to choose the fertilizer and water irrigation of the hot agricultural investment promotion network every time. With the growth of new branches and leaves, the fertilizer and water management of the hot agricultural investment network can be increased. Potted African jasmine flowers are usually changed once a year. When changing pots, some old soil and residual roots around the root system of Jasmine were removed and replaced with new culture soil to improve the aggregate structure and nutrients of the soil again, which was beneficial to Riley's growth. Change pots and water them like watering pots, so as to facilitate the close contact between roots and soil and restore growth. Before changing pots, Riley should prune once, leaving only the branches of the previous year about 10 cm, and cutting off dead branches and branches that are too dense and too thin.
1. Planting African jasmine in the southern part of the soil requires a loose and fertile sandy loam with good drainage. Potted African jasmine in the north can be prepared with 7 parts of humus soil, river sand 1 part, retted organic fertilizer 1 part and fermented sawdust 1 part. African jasmine can loosen soil/kloc-0 times a month in the growing season, and always keep the root system in a good permeable state. In addition, potted African jasmine can be changed every 1 to 2 years.
2. Potted African jasmine with fertilizer should be topdressing with thin decomposed cake fertilizer once a month during the growing season, and topdressing with phosphorus and potassium fertilizer before flowering in May to promote the flowering of plants; After autumn, add 1 or 2 times of phosphorus and potassium fertilizer to ensure safe winter. In order to prevent the leaves from turning yellow, 0.2% ferrous sulfate was added to potted plants in the northern region during the growing season. Sufficient base fertilizer should be applied when planting in the ground, and cake fertilizer should be applied to the periphery of root system in late autumn, with 0.5 ~1kg per plant;
3. Temperature: African jasmine grows well in warm climate, and the suitable temperature for growth is 18℃ to 32℃. When the temperature is higher than 38℃ in summer, it will inhibit the growth of plants. In some areas of South China, ground planting can overwinter in the open air, and potted African jasmine in the north of the Yangtze River requires that the greenhouse temperature should not be lower than 3℃ to 5℃ in winter.
4. Illumination African jasmine likes sunshine, and the primary environment is mostly semi-cloudy. In South China, as a landscaping tree, it is best to choose a shady place for planting; Potted plants in the north of the Yangtze River can receive enough sunshine in spring and autumn, and it is required to build a shed for shade in summer, or move to the shade of a big tree to avoid direct sunlight for at least a few hours before and after noon; It is particularly noteworthy that in June and July, after a long period of rain, the temperature suddenly rose and the light was very strong. We must do a good job of shading to prevent the seedlings and leaves from being burned. Potted African jasmine in public places should have enough scattered light, or be placed by the window, not too dark, otherwise the leaves will turn green, yellow or fall off.
5, moisturizing African jasmine, whether planted in the ground or potted, needs enough water, but the roots must not accumulate water, otherwise it will rot easily. Water in spring and autumn to keep the soil moist; Beware of water accumulation in rainy season; In hot summer, spray water once in the morning and evening to humidify and cool down; When African jasmine is potted indoors in winter, it is advisable to keep the soil slightly moist. When the temperature is relatively high around noon, spray a proper amount of water on the leaves. 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 probably because of accumulated water and rotten roots, and it is necessary to turn over the pots and change the soil in time; In summer, if you neglect watering, so that the newly picked shoots wither and droop, you can't water the basin soil immediately. You can spray some water on the leaves first, and then water the basin soil properly after the leaves recover slightly.
Question 8: How to maintain the leaves of African jasmine so as not to turn yellow?
The suitable outdoor temperature of African jasmine in northern China is about 20-30 degrees, so we should always pay attention to the weather changes (especially in spring and autumn, the temperature difference between morning and evening changes greatly). If the temperature is too high, it will stop growing, and if the temperature is too low, it will easily freeze to death.
In addition, the choice of soil in the basin is also very important, not too hard, so as not to make the roots unable to grow systematically. It is a good choice to add some rotten leaves or organic fertilizer to the soil.
Another important factor is sunshine. Long-term sunlight refraction in summer will shorten the life span of African jasmine. We can find something to keep out the long-term direct sunlight. If it is potted, it can be moved to the shade.
Another problem is water. It is difficult for many people to control the amount and time of watering African jasmine. In hot summer, you should spray water on jasmine leaves in the morning and evening. For the soil at the bottom, don't water it too much, don't be too dry, especially if there is no water supply at the bottom, it will rot the roots.
After autumn, many potted African jasmine leaves turn yellow and fall off, becoming unsightly. The main reason for the smell of wine is that the weather turns cold and Molly can't stand it. The first thing we should do is to clean up these yellow leaves, and then move the potted jasmine to a warm room.
It is suggested that the indoor temperature should be kept at 8- 10 degrees, and then the flowerpot should be watered every three or four days to see if it is damaged. If it is damaged, it is necessary to replace it with a good flowerpot. In addition, attention should be paid to frequent window ventilation to ensure the circulation of indoor air.
It should also be noted that if the bedroom is protected against African jasmine, it is recommended not to have too many trees, so as to avoid the low oxygen concentration in the bedroom at night, which makes people feel chest tightness and shortness of breath.
Question 9: How to raise African jasmine indoors? To make him immortal, please answer that African jasmine likes loose, fertile and well-drained sandy loam, which can be mixed with humus, river sand and peat. Always loosen the soil during the growing season to maintain good air permeability. Change the soil every one or two years. The suitable growth temperature is 65438 08℃ to 32℃. The temperature above 38℃ in summer will inhibit the growth of plants, and the indoor temperature is not lower than 5℃ in winter. In spring and autumn, you can receive enough sunshine, and in summer, you can avoid direct sunlight and provide proper shade. Sufficient scattered light can ensure the healthy growth of African jasmine, but too cool environment is easy to cause the leaves to yellow or fall off. Water supply should be sufficient, but the basin soil should not accumulate water, otherwise the roots will rot easily. Water in spring and autumn to keep the soil moist; In summer, spray water on the leaves to humidify and cool down; Reduce watering in winter. Topdressing nitrogen fertilizer once a month during the growing season can add 0.2% ferrous sulfate; Appropriate application of phosphorus and potassium fertilizer before flowering.
Question 10: How to cultivate the soil during the jasmine period in Africa in summer: It is better to cultivate jasmine soil in fertile sandy and semi-sandy soil. If planted in slightly acidic soil with pH value of 6-6.5, the root system will be dense and grow vigorously.
Maintenance of flowering period: Do not spray water on the flowers during flowering period to prevent the flowers from falling early and the fragrance from disappearing. When it rains, move the potted jasmine to a shelter.
Fertilizer and water: When jasmine is in full bloom in summer, we should pay attention to keeping the soil moist. Jasmine likes fertilizer. Top-dressing 1 times of decomposed dilute liquid fertilizer every 3-5 days, or spraying Huazhuangdiling to make the buds strong, the petals plump and the flowering period prolonged. If the pot soil is hardened, loosen the soil and fertilize it. In autumn, the amount of watering should be appropriately reduced and fertilization should be gradually stopped. Before the outdoor minimum temperature drops to 5 degrees, move the potted plants to the indoor sunshine. When you enter the room for the first time, be sure to open the window for ventilation. And control watering.
Pruning: As the flower proverb says, "Jasmine is not pruned, showing weak branches and few flowers" and "Pruning must be tough, and flowers will be stable", but people often pay attention to fertilizer and water while ignoring pruning, and even the dead branches after wintering are unwilling to prune, resulting in weak branches, small leaves, indecent plant shapes and insufficient flowers. Pruning of jasmine is very important in summer, except that the delicate branches after wintering are cut off in spring, leaving only a thick base for new buds to germinate. The branches after flower failure should be kept for 3-5 knots in time, and the top should be cut off to promote the germination of new buds and ensure the flourishing of flowers. (Pay attention to coating anti-corrosion film on the trimming mouth to reduce nutrient consumption. )
