Is the osmanthus tree easy to raise?

Question 1: Is Osmanthus fragrans easy to raise? Osmanthus fragrans has strong vitality and is an ornamental plant that is easy to grow. Osmanthus fragrans likes light and should be planted in an open area with sufficient light; However, some shade is needed at the seedling stage. Osmanthus fragrans is not cold-resistant, and the lowest temperature in winter is close to -20℃. Osmanthus fragrans has low requirements on soil and water. The soil should not be too wet, especially to avoid water accumulation, so that the roots will rot and the leaves will fall off, leading to the death of the whole plant. What effect does it have on air humidity? Requirements. Osmanthus fragrans is not tolerant to dry and barren soil, otherwise it grows very slowly and its leaves are generally yellow. It is adapted to grow in slightly acidic soil, and alkaline soil will lead to physiological iron deficiency of osmanthus fragrans. Osmanthus fragrans can't be polluted frequently, otherwise there will be a phenomenon that only leaves grow and no flowers bloom.

Question 2: Is it good to raise osmanthus at home? Perfect for people who want to lose weight.

Recently, Zhong Fang Cosmetics Co., Ltd. and Osaka University found that the fragrance of osmanthus fragrans has the effect of losing weight and relaxing easily.

Osmanthus fragrans is pronounced kinmokusei in Japanese and "Jin Guihua" in Chinese characters, which is actually not exactly the same as Osmanthus fragrans in China. Japanese-Chinese dictionary translates Japanese "kinmokusei" into osmanthus fragrans or osmanthus fragrans, and its fragrance varies with different varieties.

Experiments have proved that it is not Japanese "Jin Guihua" that has the effect of losing weight, but China's osmanthus. The fragrance of "Jin Guihua" is rich, while that of osmanthus fragrans is soft.

Professor Takashi Yamamoto of Osaka University found in his research that the fragrance of osmanthus fragrans can inhibit the increase of a component called orexin, which can feed the center and cause a great increase in appetite. In the experiment, Zhong Fang Cosmetics Company put gauze with osmanthus flowers on the chests of ten female volunteers, so that their noses could smell osmanthus flowers at any time. 12 days later, the volunteers said that they felt particularly good and in a good mood during the experiment. They felt satisfied before and after meals, and their weight and body fat decreased.

Question 3: How can osmanthus grow well? According to the growth characteristics of osmanthus fragrans, it is better to put it on the southeast balcony. If you must put it indoors, you should also choose it in front of the southeast doors and windows, so that you can receive the light to the maximum extent.

How to water potted osmanthus, from late autumn to early spring, wait until the pot soil is slightly dry or the leaves are a little wilted, and then water it once and for all. During the vigorous growth period in late spring and early autumn, water more. If you have no experience, you can water it once when the leaves are wilting, or wait until the surface of the pot soil is white and slightly cracked. Generally, when it is hot in summer, you can water it twice a day, once in the morning and once in the evening. It should be noted that if there is too much water supply, it will cause falling flowers. It is difficult to control the watering of family flowers. The most mechanical method is not to dry (wither) without watering, but to water thoroughly. When there is too much water, the leaves turn yellow.

Adjusting the temperature osmanthus is a little afraid of cold and heat. It grows only when the temperature is above 15℃ at night. For the northern region, to make it bloom during the National Day, it is necessary to move indoors before August and autumn, keep the temperature above 15℃, stop fertilization, water less (water after wilting), and then move out for maintenance in mid-September before it can bloom during the National Day.

It is difficult to find some flower soil in the city now, so you can make it yourself. 5 bowls of garden soil (made on site) 1 bowl of yellow sand. If you can get some sawdust, you'd better add 1 bowl. If there is no sawdust, use half a bowl of yellow sand instead. This is just to provide a ratio. Stir these things thoroughly and evenly, and the flower soil will be ready.

The reason for ventilation is that natural air circulation can increase the air humidity around potted flowers, increase the content of carbon dioxide around leaves, and recycle the air around leaves with germs (we will notice that moldy air is mostly a closed small space, and the air is not circulated, which is very conducive to the reproduction of various germs. This is the same as "running water does not rot"), which makes potted flowers less likely to get sick. Now many residential buildings have closed doors and windows, and the air is not circulating, especially in air-conditioned rooms. In order to save energy, the air conditioner only circulates indoor air and does not exchange with outdoor air, so its air will become more and more stale and the air humidity will be very low. Therefore, it is good for flowers and people to open doors and windows for ventilation sooner or later.

How to prune before the temperature rises above 15℃ in spring, and use household scissors or sharp blades to cut off dead branches, twigs and branches with pests and diseases, so as to make way for new branches and not give opportunities for pests and diseases to propagate. Combined with the tree shape, in the growth period, a small number of unwanted new branches are removed, and limited nutrients are concentrated to make the flowers more lush. This is the same as people, "many children make the mother bitter." But be careful, you can't cut off all the new branches, because only new branches can grow flower buds. After the flowering period in beginning of autumn, it is necessary to combine the tree shape, thin some branches that are too dense, and cut off some branches that are particularly high.

Propagation method: When the temperature rises to above 15℃ in early spring, the unbranched branches are cut into a section of about 10- 12 cm, with at least three leaf nodes or bud eyes, and inserted into a flowerpot filled with more than half a pot of nutrient soil with a depth of 1/3 (about 3-3). In the meantime, open the film every 5-7 days to breathe (one hour). Generally, hydration is not needed. If it is too dry, you can spray some water with your mouth.

Pest control If pests are found, household spray insecticides can be used; When diseases are found, the diseased leaves or branches are directly cut off.

Post-flowering treatment

Osmanthus fragrans can grow well if the pots are turned over and maintained according to the above method. After the next spring, osmanthus will be replaced with a slightly larger flowerpot. Put 3 cm of nutrient soil at the bottom of the big basin, add two caps of compound fertilizer and spread evenly; Then put the osmanthus down, cut off the root system outside the hole at the bottom of the pot, gently shake it a few times, pull it out together with the soil lump, be careful not to spread it out, put it in a big pot, add soil, press it slightly, and pour water.

Question 4: How to raise osmanthus Q: How to cultivate osmanthus? There are many kinds of osmanthus fragrans, such as osmanthus fragrans, osmanthus fragrans, Yin Gui osmanthus fragrans and Osmanthus fragrans. Osmanthus fragrans likes warm, dry and sunny environment and fertile and well-drained slightly acidic soil. Potted osmanthus needs to be replaced once a year before germination in spring, and the densely aged fibrous roots should be pruned properly. From April to September, it should be cultivated in a ventilated and sunny place, and the water should be dry and wet. Avoid watering too much or accumulating water in the basin after rain. During flowering, you should not water too much, otherwise it will easily lead to falling buds. Osmanthus fragrans likes fertilizer. In the growing season, the decomposed thin liquid fertilizer is applied every 7 ~ 10 days, and the dry fertilizer (sauce residue, about 50g per pot) is applied before and after flowering. Before flowering, it can promote flowering; Application after flowering will promote the growth of new branches in the coming year. Osmanthus fragrans is an aromatic flower, and it likes fertilizers containing phosphorus and potassium. Therefore, during the whole growth period, more fertilizers containing phosphorus and potassium should be applied appropriately. In late autumn, it is necessary to move to a cold room above 0℃ for wintering, so as to keep the basin soil slightly moist and make it fully dormant, which is conducive to flowering in the next year. Q: How to make osmanthus blossom more? A: In order to make osmanthus blossom more, we need to grasp four main links: good selection of pot soil, timely watering, skillful topdressing and proper pruning. (1) Osmanthus fragrans likes slightly acidic soil. Potted plants can be mixed with 5 parts of mountain mud, 3 parts of humus and 2 parts of sand, or half of humus and sandy loam can be used as culture soil. If the soil is too acidic, it will grow slowly and its leaves will turn yellow. In alkaline soil, leaves will wither or even die after about 2 ~ 3 months. (2) Water in time. Osmanthus fragrans should be watered with "two less and one more", that is, less water should be watered before new shoots appear, less water should be watered in rainy days, more water should be watered in dry weather in summer and autumn, and the water content of basin soil should be kept at about 50% at ordinary times. Drainage should be done in time in rainy days to prevent water in the basin from rotting roots, otherwise it will be easy to "drown". (3) Skillfully applying topdressing. Osmanthus fragrans likes pig manure, and the flower proverb says, "Be fragrant with osmanthus fragrans, and prepare more pig manure tanks". If Osmanthus fragrans leaves the room in early spring, it can be applied with decomposed dilute pig manure, about once every 10 ~ 15 days from April to May, and once every 7 ~ 1 0 days from June to July. When applying for the last 1 time at the beginning of August, osmanthus fragrans will flourish, blossom a lot and taste fragrant. There is no pig manure in the city, so you can use decomposed cake fertilizer solution. If fertilization is insufficient, there will be fewer branches and flowers, which will not be fragrant. (4) appropriate pruning. Osmanthus fragrans has developed root system and strong germination. Mature osmanthus trees germinate twice a year. Therefore, in order to make Osmanthus fragrans flourish, it is necessary to prune it properly to maintain the physiological balance between reproductive growth and vegetative growth. Generally, it is necessary to cut off long branches, thin branches and branches of pests and diseases, so as to facilitate ventilation and light transmission, concentrate nutrition, and promote osmanthus fragrans to breed more and fuller flower buds, and then bloom luxuriantly. Q: Why don't potted osmanthus flowers bloom? A: Osmanthus fragrans likes strong light, so it is warmer. Water is not allowed, for fear of oil fume. Osmanthus fragrans does not bloom, which is generally caused by five primary reasons. (1) Improper maintenance in winter. After entering the house in winter, let it sleep in a low temperature place, and it will thrive and flourish in the coming year. If the room temperature is high, osmanthus fragrans can't fully hibernate, germinate and spread its leaves in advance, and its branches are thin and consume a lot of nutrients. After leaving the house in spring, it is easy to shrink and die when encountering drought and strong wind. Too much watering in winter or insufficient light in the place where it is placed will easily cause a large number of leaves to fall off, which will affect the flowering in the coming year. (2) The planting place is too shady. Osmanthus fragrans is a long-day plant and likes strong light. If plants don't get enough light during the growing period, branches and leaves will grow in vain, which will affect the formation of flower buds. (3) lampblack. Osmanthus fragrans is not resistant to smoke and dust. If you let it live in a place with air pollution, it will grow badly, its leaves will become smaller, it will fall off easily, and there will be few or no flowers. (4) Insufficient nutrients. Potted osmanthus fragrans do not change pots and soil for a long time, resulting in insufficient nutrients and inability to stretch roots. Therefore, potted plants are changed every 1 ~ 2 years, and a small amount of hoof pieces are used as base fertilizer. (5) Overwatering. Osmanthus fragrans should avoid stagnant water, and dry and wet alternate in the growing period. If there is too much water or even rain, the water in the angel basin is easy to rot and fall leaves. Q: How to breed osmanthus? A: The propagation of potted osmanthus fragrans mostly adopts docking method, which is carried out on the first day of summer solstice. The rootstock is 2-3 years old Ligustrum lucidum with a diameter of 0.8 cm. Two-year-old osmanthus fragrans with the same thickness as the rootstock is selected as the scion, the rootstock is moved to one side of the scion, and the cortex is peeled off from the joint, and the length is 3-5 cm. Then cut a section with the same size as the rootstock at the same height of the scion, and cut it smoothly. The two layers are close together, tied tightly with plastic strips, and then ... >>

Question 5: Are osmanthus trees easy to raise in Beijing? What should I pay attention to? Osmanthus fragrans is difficult to grow in Beijing, which is a dilemma caused by climatic conditions. Soil quality can be configured, but climate factors are difficult to change. Osmanthus fragrans can't adapt to the growth in too cold places, and even if it can be planted, it is difficult to bloom. It is planted for flowering, even if it can live, it will not grow well, leading to various abnormal phenomena. Unless there are osmanthus trees that can adapt to the growth in cold areas, if there are, they can be planted. There seems to be no such variety at present. I met a osmanthus tree that has been transplanted to the north for four years, and it is also not growing well. Needless to say, even after flowering, it is difficult to see the leaves, dead or alive. This is all caused by temperature. Since it is difficult to plant, there is no need to talk about anything that needs attention. This is my personal opinion, for reference only.

Question 6: How to feed domestic osmanthus trees 1?

Guihua Gynostemma pentaphyllum

Flowers like slightly acidic soil, so potting soil can be mixed with humus or peat, garden soil, sandy soil or river sand (ratio 5:3:2). After the potting soil is made, the pH value should be kept at 5.5 ~ 6.5. Before putting the culture soil into the pot.

Disinfect with 0. 1% potassium permanganate solution. Ceramic tile basin is the best choice, and good water permeability and air permeability are the selection criteria. Because the soil matrix is limited, which is generally 1 ~ 2 years, it is beneficial for Guangxi to change the pot in early spring.

Flowers thrive.

Water tank

Flowers like high-temperature drying, so we must master the principle of "two less and one more", that is, water less before new buds sprout, less in rainy days, more in summer and autumn drought, and water at ordinary times to maintain soil water content.

About 50% is better. Pay attention to prevent the water in the basin from rotting the roots. When the summer temperature does not exceed 35℃. Therefore, when it is hot and dry in summer, you must pour enough water, once a day in the morning, and look at the dryness and wetness of the basin soil at night.

If it is dry, water it again and shade it at noon to avoid the influence of high temperature. It is best to spray water around the flowerpot frequently to cool down.

three

Osmanthus fragrans likes organic fertilizer. Generally, after osmanthus fragrans germinates in spring, it should be smeared with fully decomposed pancake fat water or pig manure every 10 days. It is best to apply compound organic fertilizer after July. The last application of liquid fertilizer, mainly phosphate fertilizer, in early September can promote the growth and flowering of osmanthus fragrans.

four

Trimming basin

It is best to plant osmanthus with short and strong trunk and well-proportioned branches and leaves. If it can't meet the requirements, it can be pruned after serving. Generally, it can be trimmed in spring and autumn. The first pruning is carried out after flowering in autumn, and the pruning should be based on the plant growth.

Prune the overgrown branches properly, so that thick short branches are evenly left on each side branch, and cut off long branches. The second pruning was carried out before germination in early spring, and some dead branches, weak branches and winter pests and diseases were cut off.

five

There are many pests and diseases to control osmanthus fragrans, so here are no examples. The main thing is to observe and spray in time.

Matters needing attention

When choosing osmanthus fragrans, it is best to choose varieties with strong resistance.

Indoor cultivation should pay attention to ensuring adequate light of osmanthus fragrans.

Question 7: Can osmanthus be planted in the north? Yes, you can. There are several kinds of osmanthus, such as June laurel and August laurel. I have a pot of June laurel at home. There has never been complicated fertilization management, just watering it on the balcony, and it grows well. I think Osmanthus fragrans is a good flower to raise.

Question 8: Can I put osmanthus trees at home? Is it good for feng shui? Osmanthus fragrans is one of the top ten traditional famous flowers in China. It is an excellent ornamental and practical garden tree, which has the functions of greening, beautification and fragrance. Osmanthus fragrans is necessary. Especially in the Mid-Autumn Festival when laurel trees are in full bloom and the night is quiet and full moon, it is refreshing to taste the wine and smell the fragrance of Chen. In ancient Chinese poems about flowers, there are also a considerable number of poems about Guangxi. Since ancient times, it has been deeply loved by the people of China and regarded as a traditional famous flower.

Osmanthus fragrans likes warmth, strong resistance, high temperature resistance and cold resistance. Therefore, it can overwinter in the open air in the areas south of Qinling Mountains and Huaihe River in China. Osmanthus fragrans likes sunshine, but also can resist shade. In full light, it has lush foliage and dense flowers. In the shade, its branches and leaves are sparse and flowers are scarce. So it is not suitable for indoors.
