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 raise White Orchid Culture methods and matters needing attention

White orchids with large flowers, beautiful appearance and slight fragrance, are very valuable ornamental plants. White orchid is a variety obtained from the original hybrid orchid, which is an evergreen plant in Southwest and South Asia. The petals of white orchids are edible and delicious. How to raise them better? Let's take a look at the culture methods and precautions of white orchids.

How to raise White Orchid Culture methods and matters needing attention

First, the culture method of white orchid-- reproduction

White orchids can be reproduced by sowing, grafting and other ways. The most common method of planting and propagation of white orchids is striping, which can make white orchids take root after two months. The white orchid obtained by grafting the branches of orchids in the rainy season can become flowers in about two months.

2. the culture method of white orchid-- covering soil.

White orchids can be planted in pots, and what the soil needs is relatively loose and breathable soil. Clay pots, purple sand and other materials can be used in the soil where white orchids are planted, and the soil particles in the basin should not be uniform. Variable diameter soil particles are more conducive to water permeability.

Third, the culture method of white orchid-pruning

After the white orchid is planted in the pot, it is necessary to have enough plant height and prune off the branches beyond the top, which is more conducive to plant growth and more buds. White orchids can cut off diseased, withered and overdense branches in time before they are moved into the pot. In this way, nutrition will not be absorbed and digested in vain.

Family culture methods and matters needing attention of how to raise white orchids

Reproduction

Grafting, cuttage, striping and sowing are the most commonly used propagation methods of Magnolia, among which grafting and striping are the most commonly used.

Striping should be carried out from June to July, using high-altitude striping method and keeping the plant moist, it will take root in about 2 months.

The biennial branches should be selected for the grafted rootstocks, and the branches of the same thickness as the rootstocks should be used in the Meiyu season. After the grafting is completed, they can heal in about 60-70 days, and then cut off from the mother plant.

Basin soil

The choice of family potted soil should not only pay attention to air permeability and looseness, but also rich in humus.

Flowerpots such as tile pots, purple sand pots and plastic pots with more bottom holes will have better air permeability, and granular soil of different sizes is more conducive to water permeability and air permeability.

Change the basin

The size of the flowerpot needs to be selected according to the crown size and age of the white orchid, which can make the growth environment of the plant more suitable.

Change the basin when the soil is slightly dry, the specific method is to let the basin tilt slowly or upside down, hold the basin while grasping the plant, pour out the white orchid and move into the new basin.

If the replacement is a new basin, you need to sprinkle a small amount of loose soil and base fertilizer in it, and then pour the water thoroughly until the planting is stable.

Planting position

White orchid potted plants are moved outdoors from March to April each year and can be placed in a place with plenty of light.

When it is hot in summer, sunshade net or simple shade shed should be used for cooling maintenance, so that the white orchid can receive sufficient light, at the same time, excessive direct light can be avoided and the branches and leaves of the white orchid can be prevented from being burned by exposure.

Pruning

Attention should be paid to the selection of height when pruning terminal buds and shortening some lateral branches, and the appropriate pruning position will promote lateral branches, buds and flowering.

Before the white orchid is placed indoors, the dry, overgrown, infected and overdense branches should be cut off to minimize the consumption of nutrients; when placed outdoors, the old leaves at the bottom of the branches can be removed as appropriate, which is beneficial to the growth of new branches.

Fertilizer application

White orchids need more fertilizer for growth, and should be fertilized every half a month or so, or 2-6 grams of compound fertilizer (nitrogen, phosphorus, potassium).

Fertilization can not make direct contact between fertilizer and roots, although watering should gradually go deep into the soil to prevent "root burning".

Applying thin fertilizer (cake fertilizer) frequently, there is no need to apply fertilizer in winter. From sprouting to June in the coming year, fertilizer and water can be irrigated every 3-4 days, and every 5-6 days from July to September. The number of fertilization can be changed according to the actual situation.

Watering

White orchids should be properly watered to avoid stagnant water. Like many domestic flowers, the method of "do not dry, do not water" is adopted; do not water too frequently, you can sprinkle water moderately to the leaves and around.

White orchids pay attention to the need to pour out the stagnant water in the basin in time after the rain to prevent the occurrence of rotten roots.

Temperature

White orchids are vulnerable to cold damage, so temperature is the key to whether they can safely survive the winter. Outside South China, they should be kept indoors in winter, and the lowest room temperature should be kept above 5 ℃ until Qingming Festival and Grain Rain can be placed outdoors again.

In the high temperature weather in summer, effective measures should be taken to cool down the white orchid.

Light

Although the white orchid needs sufficient light, it is best to put it under the shaded shed in summer, remove the shelter when the light is suitable, and restore the shelter to its position when there is strong light at noon.

The placement of white orchids indoors should give priority to the transparent position with plenty of sunshine.

Pest control

Common diseases of white orchid include yellowing, root rot and anthrax.

Before the occurrence of the disease, the resistance of the plant should be enhanced by ventilation, loosening the soil and controlling watering; after the disease occurs, scientific liquid spraying should be carried out immediately.

Common pests are red spiders, shell insects, aphids and other insects.

Before the occurrence of insect pests, it is necessary to spray water frequently to increase the humidity to prevent them; after the occurrence of insect pests, clean water can be used to wash the leaves, and insecticides should be sprayed in serious cases.
