How to cultivate white orchids in winter, control indoor temperature/reduce watering

Winter is a relatively difficult period for most plants, and the white orchid is no exception, and it does not have a strong resistance to the severe cold, so we must pay special attention to it when raising it, about how to raise the white orchid in winter. What do you need to pay attention to? Next, the editor will take you to learn about it.

How to raise white orchids in winter

If we want to know how to raise white orchids in winter, we first need to take anti-freezing measures, and then we also need to pay special attention to temperature control, watering, fertilization and so on. The details are described in detail below. Let's take a look at it.

1. Anti-freezing management

In winter, we usually keep white orchids indoors, but even if we keep them indoors, we have to take anti-freezing measures. We need to pour an appropriate amount of antifreeze water into the soil, which can improve the resistance of white orchids to cold weather.

two。 Temperature control

On how to raise white orchids in winter, temperature control is a very important link, it is generally best to control the indoor temperature above 5 ℃, so that white orchids will not appear frostbite because the temperature is too low, and must be ventilated, not too closed, otherwise it is easy to let diseases and insect pests enter, which we should remember.

3. Fertilization management

Winter is the dormant period for white orchids, so there is no need to fertilize them, we only need to fertilize them once in the first half of the winter, and we can return to the normal fertilization frequency when the winter is over.

4. Watering management

About how to raise white orchids in winter, watering is also a very important point, but there is not a specific frequency, we can maintain the principle of not drying and watering, wait until the basin soil is dry, the amount of watering should not be too large, generally appropriate amount of watering, to keep the soil with a certain degree of moisture, so as not to frostbite plants because of too much water.

5. Light management

White orchid is a kind of light-loving plant, although we usually raise it indoors in winter, you still have to let it receive appropriate light for a period of time every day, which can be chosen when the temperature rises at noon every day. at this time, we can move it to the outdoor direct sunlight and move it back indoors when the sun is about to set, which can increase the cold resistance of the white orchid.

Conclusion: after reading the above contents, I believe we all have a certain understanding of how to breed white orchids in winter. In fact, the conservation methods of white orchids in winter and the usual maintenance methods still have something in common. We can refer to the culture methods of white orchids. I believe it can bring some help to everyone.

How to raise white orchids? Pot culture methods and matters needing attention of white orchids

White orchids have a strong aroma and a long flowering period, blooming from June to October. Put one in the pocket, or a few in the living room, the aroma can last for more than ten days, even after drying and shrinking scorched yellow, using it to make tea is still very fragrant. Family cultivation of white orchids, to have a larger balcony and courtyard, and to have sufficient Yang Guan, because it is Xiyang flowers and trees, otherwise it is not good.

How to raise white orchids?

1. White orchids are neither drought-tolerant nor wet-tolerant. The weather in summer and autumn is hot, evaporation is fast, water demand is large, and watering should be timely. It is advisable to keep the soil slightly wet. Its roots are thick and fleshy, and it is most afraid of waterlogging, so the basin soil should use leached humus soil. Do not be caught in the rain in the mildew and rainy season, if the pot soil is wet for a long time, it will rot, causing the leaves to yellowing and fall off and die, which is difficult to save. This should pay special attention to the white orchid that is dormant in the room, because of the large magnolia planted in the cylinder, the wall of the cylinder is impervious to glaze, and the plant evaporation is small at this time, the topsoil in the jar is easy to dry, and the heart soil is difficult to dry. If you only see the white on the table, it will make the basin soil often wet and die. People plant white orchids to death, which often leads to this malpractice. Therefore, the basin soil is easy to be a little dry in winter, and the heart of the tank is dry, so you must not water it.

2. White orchids like fertilizer, but avoid concentrated fertilizer. In addition to pouring enough basic fertilizer when changing pots every 2-3 years, generally, after flowering, water with rotten bean cake or fishy water is watered every 7-10 days. It is necessary to master the principles of sparse application, regular application, evening and so on. Stop fattening after cool autumn.

3. White orchids are afraid of cold and like the sun. They should have more than 10 hours of sunshine every day. Even if dormant in winter, it can not be shaded for a long time, otherwise it will affect flowering in the coming year. It is more afraid of the cold than jasmine. It enters the room in early November and overwinters, and can not leave the room for maintenance until the middle of April of the following year.

4. White orchids are not resistant to pollution. Besides cannot plant in the factory area, the family maintenance also should not put in the kitchen overwintering, avoids the lampblack pollution.

Matters needing attention in potted white orchid culture

1. The fleshy root of the white orchid is most afraid of stagnant water. The potted soil needs to be acid soil with good drainage, and the basin bottom should be covered with 3-4 cm thick granular furnace ash or broken tiles to make water layer.

2. the sun is strong in midsummer, so it should be properly shaded around noon, or moved to the shade from June to August. Liquid fertilizer should be applied every 1-2 weeks in the peak growing season (May-September), and the basin soil should be kept moist regularly. In summer, it is also necessary to spray and wash the leaves and sprinkle water to the ground to make the environment moist.

3. It should be kept indoors in winter, the room temperature should be kept at about 12 ℃ during the day, and the minimum at night should not be less than 5 ℃. When you first enter the room, you should not water too little. Before and after the Winter Solstice, the white orchid entered the dormant period, need to control watering, stop fertilization and pay attention to proper ventilation.

4. If yellow leaves are found in the cultivation process, 0.2% ferrous sulfur solution should be sprayed 2-3 times in time, which can make the leaves gradually change from yellow to green. It is forbidden to apply thick fertilizer. Sufficient basal fertilizer should be applied when changing pots every 2-3 years. Thin and rotten bean cake water and fishy water should be applied every 10 days after flowering, and fertilizer should be stopped after cool autumn. Need to light more than 10 hours a day, in the winter dormancy period should also be placed in the indoor weak light or scattered light, to avoid lampblack pollution. Never move the white orchid into the kitchen during the winter. There are two kinds of yellow leaves in white orchids-chlorosis caused by iron deficiency and root rot caused by excessive water.

① chlorosis: the main basin soil is alkaline.

② root rot disease: the root system is black and rotten, and the leaves are yellow and shedding, resulting in the death of the whole plant. Therefore, it is usually necessary to wait until the basin soil surface is white before watering, and often loosen the soil.

5. Maintenance and management in spring. When shedding flowers, poke short from about 3-4 stem nodes under the residual flowers, and remove some old stems and over-dense stem nodes to facilitate ventilation and adapt to the family balcony environment. After flowering in March, there is a short period of dormancy, fertilizer and water should be stopped.

6. In summer, crab melon orchid can grow slowly at 15 ℃, and grow faster when the air is moist at about 25 ℃. When the temperature exceeds 30 ℃, even if it is in shady environment.

7. during the maintenance of autumn and winter, the temperature is still high in early autumn, foliar water and environmental sprinkling should continue. From September, crab melon orchid gradually returned to growth, and sunshine could be seen in the morning and evening with the decrease of temperature in mid-late September. In the middle and last ten days of October, all-day sunshine should be given to promote flower bud differentiation and more pregnant buds. To the first and middle of November, the temperature turned cold, crab melon orchid to enter the house for the winter, the room should also be sunny place. However, direct sunlight should be avoided in the flowering period to prolong the flowering period, the watering in autumn should be appropriate, and the basin soil should remain moist, not dry, not waterlogged, too dry, too wet, sudden drop in temperature or excessive temperature difference between day and night, which will cause falling flowers and buds.

8. Due to the low temperature in winter, the evaporation of crab melon orchid is also reduced. Attention should be paid to watering. Rotten roots often die because of too much watering in winter. Autumn and winter is the period when crab melon orchid blossoms. Every 7-10 days, topdressing with more phosphorus should be applied and fertilizer should be stopped during flowering. The temperature is changeable in winter, so it is necessary to do a good job of heat preservation and ventilation. It is necessary to prevent freezing when the room temperature drops to 5 ℃. It is common to culture crab melon orchid in some families in the south of the Yangtze River. Although it is full of buds, it is difficult to bloom when the room temperature is not kept at about 15 ℃.

White orchids can bask in the sun

Magnolia flowers like warmth, love the sun, need enough sunshine throughout the year, winter dormancy should shine a little sunshine when keeping warm, summer and autumn growth and flowering period, there should be enough light. Sufficient light, good growth, more flowering and fragrant flowers; lack of light, thin growth of branches and leaves, few flowering and poor fragrance. In addition, the basin soil should be watered when it is dry, especially in high temperatures in summer and autumn, and the basin soil should be watered thoroughly when it is dry. If the basin soil is too dry for a long time, it will cause leaf yellow shedding and affect growth. However, it should be noted that the drainage of the basin soil must be unobstructed to prevent stagnant water, otherwise, the roots and leaves will rot, and the method of fertilization, like Milan and jasmine, can be adopted to apply "thin fertilizer frequently".

White orchids shed a large number of leaves during the winter

White orchids often encounter a large number of fallen leaves when they spend the winter indoors or in the greenhouse, especially when the greenhouse is hot and cold. The reason: the first basin of soil is not dry and wet, sometimes dry and sometimes wet, fleshy roots can not bear, causing leaf water backflow, there are fallen leaves. Second, the same situation will happen when the room temperature rises, the environment is muggy and there is no timely ventilation. There is another reason, because of the cold.

In order to prevent a large number of white orchids from falling leaves during the winter, the amount of water should not be too much after the basin soil is dry. Keep room temperature between 5-10 ℃, not too high or too low. It is necessary to increase environmental humidity and indoor ventilation to keep the air flowing. In this way, the phenomenon of falling leaves of white orchids can be reduced. In addition, the white orchid after falling leaves, as long as the terminal bud is alive, the leaves will grow again after the spring comes out of the house.

How do white orchids survive the winter

Potted white orchids enter the room for the winter and often lose their leaves. At first, brown dots and dry tips appear on the leaves, then fall off, and then grow new leaves again. The main reason is that the room temperature is too high. When the temperature exceeds 15 ℃, the relatively dormant orchids sprout again. After the new buds occur, the old leaves will fall off because of the physiological phenomenon of metabolism in the new town. However, these new leaves and shoots, due to indoor light and temperature and other conditions are not enough, new leaves are weak, very easy to yellow.

Home potted Magnolia, after "the Autumn Equinox" into the room, the room temperature should not be too high, about 10 ℃ is more suitable. Pay attention to indoor ventilation, but do not directly open windows to blow cold air, potted flowers should be placed in places with sufficient light, controlled watering, and fertilization is prohibited.

After "the Beginning of Winter", if the temperature drops, you can make a plastic shed to cover the brandy, which can not only ensure a relatively stable temperature, but also ensure a certain temperature and prevent smoke and dust pollution. Note that the shed should have vents to avoid excessive temperature, enough to make the mold develop. Try to cool down when the room temperature is too high in spring.

Before and after the Qingming Festival, you can move outside at noon on a clear and windless day, put it in the leeward and sunny place, and spray water to the page. At night or in case of cold spell, it should be moved back indoors, so that when the temperature is stable above 10 ℃, it can be maintained normally outside.

How to grow white orchids? White orchid cultivation techniques and pest control methods!

The white orchid has a long flowering period and thick green leaves, so it is a popular garden ornamental and green seedling, so do you know how to grow the white orchid? Do you know how to control diseases and insect pests of white orchids? Do not know quickly Huinong net editor to have a look, the following timely Huinong net Xiaobian finishing the prevention and control of white orchid diseases and insect pests!

Ecological habits of white orchids:

White orchids like warmth and are not resistant to cold. The northern potted plant should be moved indoors in winter and placed in a sunny place. The chamber should be kept above 12 ℃, and 15 ℃ is the most suitable. Under this temperature, the leaves can be kept. If the cold causes the leaves to fall in winter, it will affect the flowering the following year. White orchids like sunshine and cannot bear shade. When the weather gets warmer in spring, move it outside and put it in a sunny place. The summer climate is hot, the air is dry, can be properly shaded, and fully watered and sprayed.

White orchids like water, can not bear to dry early, afraid of waterlogging. If the leaves are found to be red, it means that the root system has been damaged by water, and it is necessary to stop or reduce watering, otherwise it will cause fallen leaves. Water less when it is cool in autumn. In order to prevent stagnant water, you can pad some broken bricks and tiles at the bottom of the basin to facilitate drainage and avoid rotten roots and yellow leaves.

White orchids like acidity, and acidic or slightly acidic sandy loam is suitable for soil. Although most of the soil or water in the north is alkaline, it is easy to cause poor plant growth and yellowing of leaf color. In this case, to reduce watering, while using black alum water to water flowers, can gradually eliminate the yellowing phenomenon, so that the leaf color slowly turn green.

White orchids like fertilizer and water, and can be watered with alum every 4-5 days in the growing season, usually in the afternoon and then in the evening to dilute the fat and water to disperse the root heat and prevent root burning. Fertilization has been stopped since August. White orchids sprout twice a year. The first time in spring, the second time in summer. Branches can grow more than 50 centimeters a year. Before the second germination, there is a period when the branches stop growing. At this time, it is necessary to maintain sufficient light and strengthen fertilizer and water management to promote the second germination. Generally speaking, the mature bean cake can be watered once every 3 or 4 days, so as to achieve the purpose of blooming at the same time.

Cultivation and management skills of white orchids:

White orchids are not resistant to pruning and maintain their natural state in principle. In summer, attention should be paid to timely cutting off overgrown roots and dead branches in order to maintain a beautiful tree shape and reduce nutrition consumption.

The work of coming out of the room of white orchids is very important. When the weather is getting warmer from winter to spring, evaporation increases significantly in the northern region because of the dry climate. If the white orchid is poorly managed in winter and its roots are damaged and moved out in a hurry in early spring, it will make a large number of leaves fall off, branches shrink, or cause death. When you find this kind of situation, you must not rush out of the room, first restore the root system indoors, wait for the branches and leaves to grow vigorously, and then gradually move out. Summer should be put on the benefits of good ventilation, because the climate is dry and hot, poor ventilation, it is easy to cause red spider plant harm and disease.

The pots of white orchids are changed every 1-2 years, mostly before leaving the room from March to April. The soil uses acid sandy loam with loose and fertile soil and good drainage.

White orchids are often propagated by grafting. The time is from May to August. Magnolia is used as rootstock and one-year-old branches are used as scions. It can be cut in about 40 days. It can also be propagated by striping. Cuttage propagation is not easy to survive, so it is not often used.

Control methods of diseases and insect pests:

The main diseases and insect pests of white orchids are Rhizopus, aphids and shell insects.

(1) Rhizopus: mildew and white hairs on the roots. The main reason is that the basin soil is too wet. The root soil can be removed to reveal the root of the disease, and then removed with gypsum powder to sterilize. It can also be poured with light lime water after the basin soil is slightly dry.

(2) aphids, sprouting in spring is often harmed by aphids. Aphids are very small and adults have or do not grow wings. The reproduction is very fast, and the harm is serious. It has piercing and sucking mouthparts, which usually gather on branches, leaves, buds or pedicels, absorbing sap from tender tissues, causing branches and leaves to wrinkle and deform, flowers growing poorly or not fully blooming. The honeydew it secretes from time to time cultivates a kind of coal fouling bacteria, which spreads virus disease and many other hazards, and produces a layer of black cover in the damaged branches, affecting normal photosynthesis and ornamental value. The control method is to ensure that the plant is ventilated and transparent, and the foliar surface is often sprayed with boiling water. Aphids can be sprayed with 800x fenitrothion or 2000 times omethoate.

(3) scale insects, which are often harmful to the back of the leaves. The method of control is the same as that of other flowers.

The above is the summary of the growth habits and cultivation management techniques of white orchids by the editor of Huinong Network. I hope it will be helpful to the growers!
