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 ℃.
