What are the key points for growing orchids? A detailed guide

 Except in early spring and winter, orchids should be placed under open-air shade frames. The shade frame must be well ventilated. When orchids are first brought out in March to April, they can get more sun, and afterward the shading time gradually increases. In winter, orchids must be moved indoors to protect them from the cold, and the room temperature only needs to be kept at 1C to 2C. In addition, after orchids are brought out in spring and before they are brought in in autumn, care should also be taken to prevent frost damage.

 For planting orchids, cake fertilizer is suitable. Mix 4 parts plant ash, 10 parts soybean cake, and 10 parts bone meal thoroughly, place in a vat, add water several times until the soybean cake is soaked and swollen, then cover and seal. After one year of decomposition, make it into dry granules. It can be placed on the surface of the pot when used. If whole manure is used, it should also be decomposed for one year, then diluted with water, and the residue filtered out before use. Generally, fertilizing starts in May and stops at the Beginning of Autumn. The principle is to apply thin fertilizer frequently. Fertilizing should be done in the evening, and the next morning water once with clear water.

 When watering orchids, rainwater or spring water is preferable. Water containing salt and alkali should not be used. If tap water is used, it should be left to stand for several days before use. Watering should depend on the temperature. In spring, the amount of watering should be smaller, and in summer it should be more. The plum rain season coincides with orchids sending out leaf buds, so the potting soil should be slightly dry. After autumn, when the weather turns cooler, the amount of watering should be reduced appropriately, and keeping it moist is enough. In winter indoors, it should be dry, watering frequency should be reduced, and it is best to water at noon. Orchids can tolerate light rain, but continuous rain or heavy rain can easily cause heart rot and leaf rot, so attention must be paid to rain protection.
