How to raise osmanthus, potted osmanthus cultivation methods and precautions (more watering sun)

Speaking of osmanthus, I believe everyone is familiar with it. Many people think osmanthus can only be planted in the ground, but it is not. With the advancement of potted technology, osmanthus can also be cultivated at home. Osmanthus fragrance floating ten miles, deeply loved by people. However, many people do not know how to raise potted osmanthus flowers. Let's take a look at the cultivation methods and precautions of potted osmanthus flowers.

1. How to raise potted osmanthus flowers to avoid strong sun exposure

The fragrance of sweet-scented osmanthus is famous for its fragrance. We said earlier that sweet-scented osmanthus can be cultivated in potted plants at home, so how to raise sweet-scented osmanthus? In the cultivation methods and matters needing attention of potted sweet-scented osmanthus, what we need to pay attention to is its watering amount and light. Sweet-scented osmanthus likes the sun, but to avoid the strong sun, watering should pay attention to water thoroughly. As long as we pay attention to these two points, growing sweet-scented osmanthus is not a problem.

2. Culture methods and matters needing attention of potted sweet-scented osmanthus

1. Selection of pots and flowerpots.

When potted sweet-scented osmanthus is planted, the potted soil can be prepared with mud / rotten leaf soil: garden soil: sandy soil at 5:3:2, or garden soil: barnyard manure: River sand at 1:1. When putting on the basin, mature organic fertilizer and bone powder should be added as base fertilizer. When potted sweet-scented osmanthus, it is recommended to choose a tile pot with good air permeability. The bottom fan follows the tile to facilitate drainage.

2. Planting time

How to raise potted osmanthus? First of all, we should pay attention to its planting time. The planting time of sweet-scented osmanthus should be from November to early December in late autumn, or from February to March in spring, and the seedlings should be planted in spring as far as possible to avoid freezing injury in winter. After putting on the basin, it should be watered thoroughly, put it in a ventilated place to slow down the seedlings, and move to a sunny place for maintenance after 1 week.

3. Watering

Sweet-scented osmanthus potted soil should grasp the principle of whether it is dry or irrigated, and if it is watered thoroughly. Generally, it is watered every 3-4 days in spring and autumn, once every day at high temperature in summer and every 7-10 days in winter. It must be watered in the morning and evening in summer and before or after noon in winter, so that the water temperature is close to the soil temperature and does not cause sudden cold and heat and damage the root system. Appropriate amount of water should be watered in autumn, and the basin soil should be prevented from getting too wet or stagnant water in the rainy season.

4. Fertilization

Osmanthus fragrans mainly watch flowers and should provide adequate fertilizer. During shoot shooting, nitrogen fertilizer could be applied twice to promote the growth of branches and leaves, while phosphorus fertilizer was mainly applied before flower bud differentiation and flowering. Before applying fertilizer, the basin soil should be a little drier, and it is appropriate to loosen the soil so that the fertilizer can be absorbed. Water should be watered once on the second day of fertilization. If compost or stable compost is used, it must be completely rotten before use. When applying chemical fertilizer, the concentration of calcium superphosphate should not exceed 2%.

5. Pruning

The shaping and pruning of sweet-scented osmanthus should be carried out after autumn, and the upper branches should be cut off to balance the tree potential. The branches that are too dense should be thinned, and the diseased branches should be removed to concentrate nutrients for flowering. Plastic pruning combined with water and fertilizer management can improve the robust growth of sweet-scented osmanthus bonsai and maintain a graceful posture. Knowing how to raise potted sweet-scented osmanthus and how to raise it, now let's take a look at its points for attention.

Matters needing attention in cultivating sweet-scented osmanthus

1. Osmanthus fragrans is a long sunshine flower, which likes strong light and is resistant to semi-shade. Lack of light, excessive dampness, easy to produce soot disease, causing fallen leaves, long, thin branches, poor flower bud differentiation, and then affect flowering, or can not blossom.

2. Osmanthus fragrans requires high fertilizer and water conditions, and insufficient nutrition will lead to poor growth and affect the quality of flowering. It is required to apply nitrogen-based fertilizer before shoot germination in December, June and September.

3. Smoke prevention and pollution sweet-scented osmanthus is most afraid of smoke pollution. In the environment polluted by soot and dust, the leaves will lose green, become smaller and easy to fall off, blossom less, flower quality is poor, or even do not bloom. If there is dust stain, spray water to wash the leaves and keep the leaves clean. The above are how to raise sweet-scented osmanthus, potted sweet-scented osmanthus culture methods and points for attention, I hope to help you.

Pure love, sincere

Magnolia (Michelia alba), alias: White Burmese flower, white orchid, Burmese sweet-scented osmanthus, Tiannu Mulan, Huang Gran, Huang Guolan, etc. The tree belonging to Magnoliaceae and Michelia is derived from the natural cross between Michelia champaca and Michelia mandshurica. It grows in South China, Southwest China and Southeast Asia. It is an evergreen native plant. Its flowers are shaped like buds of Pueraria lobata and can grow to a height of 10m and 13m. It is common in the south of our country, which is easy to grow and fragile, and is often adopted by passers-by. Flower words: pure love, sincere. It is designated as one of the "six flowers" in the "five trees and six flowers" by Buddhist monasteries.

1. Morphological characteristics.

Growth habit

Evergreen trees, up to 17 m tall, with wide branches and a broad umbrella-shaped crown; DBH up to 50 cm; bark gray; scented branches and leaves; shoots and buds densely yellowish white puberulent, hairs gradually falling off when old. Leaves thinly leathery, long elliptic or lanceolate-elliptic, 10-27 cm long and 4-9.5 cm wide, apex long acuminate or caudate-acuminate, base cuneate, upper glabrous, lower sparsely puberulent, reticulate veins conspicuous on both surfaces when dry; petiole 1.5-2 cm long, sparsely puberulent; stipules cuneate to middle of petiole. Flowers white, extremely fragrant; tepals 10, lanceolate, 3-4 cm long and 3-5 mm wide; connectives of stamens protruding long tip; gynoecium puberulent, pistil stalks ca. 4 mm, carpels mostly rudimentary, usually partially rudimentary, forming sparse aggregate fruits of follicles as receptacles extend at maturity; follicles bright red when ripe. Flowering from April to September, blooming in summer, usually sterile.

2. Growth environment

Sex like light, afraid of high temperature, not cold-resistant, suitable for slightly acidic soil. Like warm and humid, not resistant to drought and waterlogging, sensitive to sulfur dioxide, chlorine and other toxic gases, poor resistance.

3. Distribution range

Distribution: cultivated in Beijing and south of the Yellow River Basin. In ancient times, it was mostly planted in front of pavilions, platforms, buildings and cabinets. Now it is more common in gardens, factories and mines to plant alone, scattered planting, or on both sides of the road as street trees. There are also potted plants with piled scenery in the north.

Originally from Java, Indonesia, it is now widely planted in Southeast Asia. China's Fujian, Guangdong Hanmi Hatton, Guangxi, Yunnan and other provinces and regions are very popular, many provinces and regions in the Yangtze River basin pot, overwintering in the greenhouse. There are also about 49 species of plants of the same genus. The flowers of Magnolia have a very unique and pleasant aroma, so they are generally planted as ornamental plants to bring aroma to the garden. White orchids can generally bloom twice, the first in summer, the second in autumn, summer flowers are more, the color is generally milky white. Leaves light green, alternate, long elliptic and apex pointed, leathery, epidermis glabrous, ca. 10-20 {%}-m.

4. Methods of reproduction

Reproduction: commonly used striping and grafting propagation. The striping was kept moist by high-altitude pressing from June to July, and took root about 2 months later. Grafted with two-year-old Magnolia as rootstock, the branches of white orchid with the same thickness as rootstock were selected in the plum rain season, then healed in 60-70 days and cut off from the mother plant to form seedlings. White orchid can be propagated by grafting, striping, cutting, sowing and other methods, but the most commonly used are grafting and striping.

To trim potted white orchids, choose the appropriate height, cut off the terminal buds and cut some side branches with shears. After the terminal bud is cut off, it is beneficial to how long the lateral branches are, and the longer the buds are, the more they bloom.

Grafting [grafting propagation] there are two grafting methods, one is relying on grafting, the other is cutting grafting.

Connecting: depending on the time, from spring to autumn, the whole growing season can be carried out. Most of them are carried out from April to July. The best place to lean on is 70 cm from the ground. After being tied up, it is wrapped in a mass of mud and wrapped in leaves to prevent Rain Water from scouring. It can be cut off after about 60 days. Grafting is an easier way to survive, but it is not as exuberant as cutting.

There are also two kinds of striping propagation: ordinary crimping and college crimping.

① ordinary striping: the pressing is best carried out in February to March, cut the base of the branch to be taken into half the depth, then cut up a section, and then stick a tile in the middle, then gently press into the soil without breaking, insert it into the soil with "U"-shaped thick wire, fix it, prevent it from warping, and then pile it on the soil. After the root bud is sent out, the strip can be cut off and planted in spring.

② high branch crimping: select robust and disease-free twigs (1.5-2cm in diameter) on the mother plant before volley, cut the cracks in the lower part of the basin fork, then cover it with bamboo tube or bottomless clay pot, fill it with culture soil, tie it tightly with string outside, be careful not to touch it, often spray a small amount of water, keep moist, and grow new roots around May of the following year.

5. Main value

Garden value white orchid plant shape erect branched, generous. It can be cultivated in the open courtyard in the south, and it is the backbone tree species in the southern garden. Potted plants in the north can be arranged in courtyards, halls and conference rooms. Small and medium-sized plants can be displayed in the living room and study. Because of its fear of smoking, it should be placed in the air circulation place. In addition to being able to view both flowers and leaves, as a spice plant, white orchid can also be used as both spice and medicine. White orchids contain aromatic volatile oils, antioxidants and fungicides, which can beautify the environment, purify the air, and fragrance the rooms; and the essential oils and dried spices extracted from them can also be used for beauty, bathing, diet and medical treatment. Not only the extract of Magnolia can be used medicinally, but also the whole flower can be used as medicine directly. it is said that it has an excellent effect on chronic bronchitis, chronic cough, prostatitis and so on.

In addition, white orchids can also be used to smoke scented tea. according to relevant records, pure white orchid tea "has a tight shape, dark green color, fresh and long-lasting aroma, strong and mellow taste, bright yellow-green soup, and bright leaves." In the 1960-70's, some girls in Hong Kong and Guangdong liked to insert it in their hair. After the 1980s, most of the hairpin flowers were middle-aged and elderly women.

The flowers are white and fragrant, blooming between summer and autumn, the flowering period is long, and the leaves are dark green. It is a famous ornamental tree species in the garden, mostly planted as street trees. Flowers can extract essence or smoked tea, can also be extracted for medicinal use, there are qi turbid, equivalent to treating cough. Fresh leaves can be extracted sesame oil, called "Magnolia leaf oil", can be used for the deployment of essence; root bark medicine: treatment of constipation.

Skin care effect

White orchid extract can brighten the complexion and improve the dark yellow and uneven skin tone. Many cosmetics have added white orchid as an active ingredient.

Fengshui value 1. White orchids are white flowers, which are more suitable for growing in bedrooms, and are especially recommended to people whose signs are mice and pigs, because these two kinds of people are most suitable for planting flowers and plants belonging to gold and water. At the same time, in the year of Yi Geng, people who belong to gold in the five elements, such as those born in 1955, 1960, 1965, 1970, 1980, and 1985, whose Mantissa is 5 and 0, are the most suitable for growing white flowers or plants that seem to kill them. for this kind of friends, white orchid is a good choice. In addition, the flower language of the white orchid: pure love, sincere. Planting white orchids in the bedroom is helpful to promote the relationship between husband and wife.

2. The growth environment of white orchid not only improves the growth environment of the house, but also improves the dominant fengshui environment of the owner. Magnolia flowers like to be warm and moist, should be well ventilated, have sufficient sunshine, fear cold, avoid dampness, neither shade nor sunburn, which gives the owner a standard to judge whether the home environment is suitable for warmth, moist and ventilation. if a home's white orchid grows well, it proves that these writing conditions have been achieved. These conditions are the criteria for judging whether a house is good or bad. If you don't know whether your fengshui is good or not, plant a white orchid to judge.

3. The fragrance of white orchids creates a good fengshui at home. As we all know, there is a kind of perfume called white orchid, which works quite well: aromatherapy relaxes the mind, relaxes the mind, promotes appetite and stimulates the body's potential immunity; aromatherapy can purify the air and improve air quality. create a pollution-free human living space; aromatherapy can promote metabolism, reduce fatigue and help maintain respiratory skills; aromatherapy can create a romantic atmosphere, romantic aphrodisiac, promote lust Aromatherapy can regulate physiological function, beauty, relieve mental pressure, promote exuberance and improve work efficiency. Let's just imagine that usually we live at home, where we can eat well, live well, work smoothly, and have good health. The use of white orchid perfume can keep us alive. The main ingredient of white orchid perfume is white orchid, put a white orchid at home, believe that its effect is less than where, the above ideal of life can be realized sooner or later.

6. Culture technology

Potted white orchids in flowerpots and soils should be cultivated in soils that are loose, breathable and rich in humus. Usually choose tile basin with good air permeability, purple sand basin (cylinder) or plastic basin with more bottom holes. The soil in the basin had better have a certain amount of granular soil of different sizes to facilitate water seepage and air permeability.

Change pots and pots of appropriate size according to the crown size and age of white orchids to facilitate the exuberant growth of plants. During the operation, you should wait for the pot to dry, tilt the pot (jar) slowly (or upside down), hold the basin in one hand, grasp the plant in the other, and pour out the white orchid and move it into the new pot. The new basin (tank) should be padded with a small amount of loose soil in advance, then irrigated thoroughly, and the planting can be stable.

Planting location from March to April every year, the pots and jars with white orchids are removed from the outside and placed in a sunny place. High temperature in summer, should be appropriate to choose a sunshade net or build a simple shade, so that the white orchid can not only shine on the morning sun, but also avoid the strong light in the summer afternoon (so as not to burn branches and leaves due to exposure). Fertilization during the vigorous growth period of white orchids (usually in May, June or July and August of each year), flower fertilizer should be applied to white orchids every half a month or so, or a little nitrogen, phosphorus and potassium compound fertilizer should be applied at intervals of about 20 grams, 2 grams to 6 grams each time.

The specific operation is: first use a small shovel to draw several vertical and horizontal ditches of the soil in the basin, then slowly spread the fertilizer into the ditch, then cover it with the topsoil in the basin, and pour some water. Make the fertilizer gradually infiltrate into the root of the plant with each watering. Do not spread the fertilizer directly to the root, so as not to "burn the root" due to the heavy fertilizer effect of the soil around the root. It is better to apply thin fertilizer frequently, cake fertilizer is better, no fertilizer is applied in winter, fertilizer and water are irrigated every 4 days from July to September, once every 6 days from July to September, and once after several times of fertilizer application.

Proper watering is the key to the conservation of white orchids. White orchids should not be overwatered or overwatered. The correct watering method should be to moisten the soil in the basin at one time, but it is not necessary to water the soil in the basin when it is slightly dry. Remember not to water every day, but you can often spray water on the leaves with a small spray can. In summer, water should be irrigated not less than three or four times a month (plus spraying water on the leaves). The easier way to master is to water the white orchid as long as you see its leaves drooping. It is watered two or three times a month in autumn and once or twice a month in winter.

Because of the fleshy root system, it is afraid of stagnant water and is not resistant to dryness. Water once out of the house in spring, then once every other day; once in the morning and evening in summer, foliar water should be sprayed if it is too dry; once every 3 days in autumn; buckle water in winter, as long as the basin soil is slightly moist; pour the stagnant water in time after rain.

The temperature is not cold-resistant, except for South China, all other areas should enter the room for maintenance in winter, the lowest room temperature should be kept above 5 ℃, and the time to leave the room should be from Qingming to Grain Rain.

7. Plant maintenance

Management and maintenance in July, August and September is the peak growing season and full bloom of white orchids. During this period, if not properly maintained, the leaves will wither, even the whole plant will die. If well maintained, it will flourish and bloom continuously. According to the author's experience, the maintenance here should master the following points:

⒈ light to soft white orchid like light, summer can be placed under a shaded shed, open the curtain in the morning to allow it to receive sunshine, after 9 o'clock should cover the cover, shelter from the sun, especially to avoid the noon bright light.

⒉ water should be diligent.

White orchids like to be moist, and they should be often watered in summer, and it is best to water once every morning and evening. In high-temperature weather, they should also spray water twice on the leaves and around them in the morning and afternoon to increase humidity, because their roots are fleshy roots and are afraid of stagnant water. should also be less watered or not watered on cloudy and rainy days. In case of rain, the drainage in the basin should be paid attention to in time to prevent the root from soaking and rotting, resulting in the death of the whole plant. Because the white orchid is a typical acidic flower, afraid of alkali, the water alkalinity in the north is greater, and the leaves are easy to yellowing and falling off after long-term use, so it is best to use Rain Water at intervals when watering, and ferrous sulfate can also be used for watering.

⒊ fertilizer to the big white orchid in the growing period like big fat water, not only should be well watered, but also should be well fertilized. It is best to use liquid fertilizer to fertilize, mix horseshoe slices, sesame paste and ferrous sulfate at the ratio of 1 to 1 / 0.5 and soak in water for a week. After fermentation, the effect is better when diluted with water every 5 days. The flowers and leaves are broad and thick, and the flowers are fragrant. Disease-resistant white orchids are most vulnerable to red spiders in summer. It is usually necessary to spray more water to the leaves and plants to increase humidity and prevent the occurrence of insect pests. If there is a small number, you can use a sprayer to wash the leaves with clean water. If the number of insects is more, 1000 times the amount of triclofenac EC can be sprayed to get rid of insects.

After the white orchid enters the winter, the following points need to be done to survive the winter safely.

⒈ temperature. Temperature is the key to whether white orchids can survive the winter safely. After entering "the Autumn Equinox", the white orchid should be moved indoors, and the temperature should be maintained at 5: 10 ℃. When the temperature is too high, it should be cooled properly.

⒉ humidity. Spray into the air frequently to increase the humidity of the surrounding environment. Windows should be opened for ventilation from 10:00 to 2 pm on sunny days, but cold winds in the north should be avoided.

⒊ illumination. After moving into the room, the white orchid should be placed in a sunny place.

⒋ water. Watering should be controlled, watering should not be allowed until the basin soil is completely dry, and fertilization is prohibited.

⒌ is the transitional stage before and after the Qingming Festival. When the temperature is warm, the plants can be moved to the outdoor sunny shelter at noon, foliar water spraying can be carried out, and then moved indoors in the afternoon. When the temperature is stable above 10 ℃, it can be moved to the outdoor for normal maintenance. Note: White orchids are tropical tree species, like warm light, afraid of cold and smoke, raised in the north pot, need to pay attention to the following 6 points:

1, do a good job of anti-freezing and warm work, the indoor temperature is maintained above 12 degrees during the day and not less than 6 degrees at night, otherwise it is vulnerable to low temperature and cold damage. Circulate the air and keep the soil moist in order to survive the winter safely.

2. The Beginning of Summer moves back and forth to the outdoors and should be placed in a sunny ventilation place. The sunshine should be more than 6 hours. Only when there is enough light, can it grow well. If there is not enough light, it will grow branches and leaves, blossom less or not. And in the hot summer season, the sun intensity, should be a little shade, so as not to burn leaves and tender stems.

3. Prevent smoke pollution, keep the leaf surface clean, and spray the leaf surface if necessary, so as to facilitate the normal development and growth of the plant.

4. White orchid is fleshy root, the temperature is higher in summer and autumn, the watering amount should be large, and the basin soil can be kept moist in winter. It is necessary to effectively prevent the basin soil from getting too wet or stagnant water, otherwise it will affect the growth of the root, and when it is serious, it will make the root black and rotten, causing the leaves to fall off and die.

5. From moving outdoors to the end of June, alum fertilizer water was irrigated every 7-10 days to make the soil slightly acidic. The rapidly available phosphate fertilizer can also be applied at flowering stage to make it spit incense continuously.

6. Before entering the room, withered branches, diseased branches, overgrown proud branches and over-dense branches should be removed to minimize the nutrient consumption of the plant. When leaving the room, the old leaves in the lower part of the branches can be properly removed, which is beneficial to the growth of new branches. In addition, it is necessary to pay attention to aphids and other harm to twigs and shoots, which must be controlled in time.

8. Species differences

Species of the same genus: yellow orchid, also known as yellow Burmese cinnamon, orange, sweet and moist like sweet-scented osmanthus, more fragrant than white orchid! The florescence is later than that of Magnolia.

Michelia flowers, smaller than Magnolia, yellow-white, solitary in the axils of leaves, with banana-shaped fragrance.

9. Plant culture

Pure love, sincere

How to raise Osmanthus fragrans in four Seasons? what about the leaves of Osmanthus fragrans?

Sweet-scented osmanthus is a plant that blossoms all the year round. There are many potted sweet-scented osmanthus in the north, and they have high economic value, so many flower friends will breed them indoors. So, how to raise sweet-scented osmanthus in the four seasons? What about the leaves of sweet-scented osmanthus in the four seasons? Next, I would like to introduce the culture methods of sweet-scented osmanthus, as well as the reasons and solutions for the loss of leaves of sweet-scented osmanthus.

How to raise sweet-scented osmanthus in the four seasons

1. To choose a good basin of soil.

Osmanthus fragrans like slightly acidic, well-drained, fertile sandy loam. Osmanthus fragrans grew slowly in strong acid soil, yellow leaves withered and few branches, and in the soil with pH 3-4, the two-year-old seedlings had 2-3 branches in the same year, and the branch length was only 6cm, which was 2 times less and 1-2 times shorter than that in the soil with pH 6. In alkaline soil, leaf withered ginger appeared in two or three months and gradually died.

two。 Watering

Osmanthus fragrans like high temperature and dry environment, so it is necessary to have a good grasp of watering. It is most appropriate to water more in the summer to keep the soil moist at about 50%. And when it is overcast and rainy and sprouting, ah, less watering, anyway, the basin soil is stagnant water, so as not to cause rotten roots. Shade treatment in summer, the temperature can not be higher than 35 degrees Celsius, and spraying water around the flowerpot can achieve the cooling effect.

3. Fertilizer application

The bloom lies in fertilizer, and sweet-scented osmanthus likes pig dung. Can be mixed in the basin soil, or cooked and dried in the basin bottom. The amount of fertilizer application is based on the pot height of 1amp 4, and the fertilizer should be covered with a layer of soil about 1 inch to 2 inches thick, and then planted with cinnamon, there is no need to apply fertilizer within a year. In places where there is no pig dung in the city, the horns of donkeys, horses and mules can be watered into water. They can be watered once when they sprout in spring and every 7-10 days before August. Can also be fried with sauce dregs, soybeans, peanuts, research into noodles, dig ring root holes buried in the basin soil. It is observed that if you are fat, the flowers will be prosperous and fragrant, and the flowers will be 2 times and 3 times more. Lack of fertilizer, few branches, few flowers, no fragrance.

4. Pruning

The four seasons sweet-scented osmanthus can be pruned in the roar of spring and autumn, after blooming in autumn for the first time, and then pruning off the longer and too dense branches of the plant to leave sturdy short branches. The second pruning is before sprouting in early spring, pruning off dead, weak and diseased branches so that it can sprout better. Generally meet the requirements of short and strong, thick trunk and symmetrical branches and leaves.

5. Prevention and control of diseases and insect pests

The diseases and insect pests of sweet-scented osmanthus in the four seasons are more harmful, such as brown spot, blight, anthrax and so on, which can be eliminated by corresponding drugs or manually.

What about the leaves of sweet-scented osmanthus in the four seasons?

1. Sweet-scented osmanthus trees turn over the soil in four seasons

When buying sweet-scented osmanthus trees, whether to bring flowerpots, sweet-scented osmanthus trees change pots, resulting in sweet-scented osmanthus tree root injury recovery time is very long.

Remedy: if the root injury is not serious, new leaves can be sent, and pruning can not be observed to save life.

2. Osmanthus fragrans are placed outdoors.

Sweet-scented osmanthus is a woody plant, which is not suitable to be placed indoors for too long in summer. Generally, it should be put outdoors for about 2-3 days, and let it bask in the sun and drink dew, otherwise the leaves of sweet-scented osmanthus will fall off or turn yellow in the four seasons, and eventually die.

3. Osmanthus fragrans trees are watered in four seasons

(1) too little watering

The water was not done well, because the cinnamon tree grew in the basin for a long time, and the water we watered did not soak the basin soil, but flowed away directly from the edge of the basin, resulting in a lack of water. If this is the case, you can use a container slightly larger than the basin to fill the water, put the whole flowerpot in the water and let the pot soil absorb the water. Wait for the laurel tree to return to exuberant growth and choose to change the pot.

(2) overwatering

Sweet-scented osmanthus tree leaves fall off, too much water, the four seasons sweet-scented osmanthus is a drought-tolerant plant, watering should not be too often, pot soil drainage is poor or too wet, will cause poor growth, root rot, leaf shedding, and eventually lead to the death of the whole plant.

The above is for you to introduce the four seasons sweet-scented osmanthus culture methods, as well as the four seasons sweet-scented osmanthus leaf reasons and solutions, we are clear? Please pay attention to more household knowledge.
