For loose and fertile soil rich in humus, humus soil or self-made nutrient soil is recommended. Keep the soil moist and water it once every two or three days in spring and autumn, once or twice a day in summer and once a week in winter. Avoid direct sunlight and keep cool. Temperature, normal room temperature is enough. Fertilizers should go through decomposed liquid fertilizer.

1, soil

Orchids are generally planted in humus-rich, loose and fertile soil, which can be planted directly with humus soil or configured by themselves. Humus soil, perlite and river sand are evenly mixed according to the ratio of 7:2: 1 to make culture soil, and perlite can also be replaced by compost.

Step 2: Moisture

Different varieties have different water requirements, but generally follow the principle of wetting but not accumulating water to maintain the micro-tidal state of basin soil. The autumn climate is dry, which can increase moisture appropriately. You can also spray water on the leaves with a watering can to increase the humidity of the air. Water should be poured every two or three days in spring and autumn, and once or twice a day in summer with strong sunshine and strong evaporation.

In winter, the temperature is low, and orchids basically enter the dormant period. At this time, it is necessary to reduce the amount of water appropriately to avoid water accumulation, root rot or freezing, and water it once a week.

3. Lighting equipment

Orchids like semi-cloudy environment and avoid direct sunlight, especially orchids. When orchids are maintained, shading treatment should be carried out in spring, summer and autumn. You can build a shading shed or put it under the eaves and other cool and ventilated places for maintenance, which can accept scattered light and get the best illumination in the morning and evening. In winter, it can be placed indoors under the window sill with light and out of direct sunlight.

4. Temperature

Orchids like warm environment and can thrive at normal room temperature, and the temperature is controlled at 15 to 25 degrees. The temperature is low in winter, so I moved him indoors for maintenance. The temperature is about 1 1 degree, so it is more appropriate to keep him indoors for 5 to1degree. Pay attention to ventilation, and the humidity should not be too high. The temperature is too high in summer, so don't get sunburned. Keep the temperature below 28 degrees.

5. Fertilizer

Don't apply too much concentrated fertilizer to orchids, use liquid fertilizer, or use Woye amino acid foliar fertilizer. In the vigorous growth period, decomposed cake fertilizer can be applied once every half a month to twenty days, which is also a kind of thin fertilizer. Because the roots of orchids are special and fleshy, in order to avoid rotten roots, the fertilizer applied must be decomposed.
