In general, we choose humus rich, loose and fertile soil to cultivate orchids, which can be directly planted with saprophytic soil or configured by ourselves. The sapropel, perlite and river sand are mixed evenly according to the proportion of 7:2:1 to make culture soil. Perlite can also be replaced by compost.
Different varieties of water demand is different, but generally follow the principle of moistening but no ponding, to keep the basin soil moisture state.
In autumn, the climate is relatively dry, and the water content can be increased appropriately, or spray water on the leaves with a watering can to increase the air humidity. In spring and autumn, water once every two or three days. In summer, the light is strong and the evaporation is strong. You can water once or twice a day
Winter temperature is low, orchids have basically entered a dormancy period, at this time to reduce the amount of water, to avoid waterlogging roots or freezing, water once a week.
Orchids like semi shade environment, avoid direct sunlight, especially Mulan. When curing orchids, shade treatment shall be carried out in spring, summer and autumn. Shade shed can be built or placed under the eaves and other cool and ventilated places for maintenance, which can receive scattered light. The light in the morning and evening is the best. Winter can be placed in the light of the indoor windowsill, direct sunlight can not reach the place.
Orchids like a warm environment. They usually thrive at normal room temperature. The temperature is controlled at 15 to 25 degrees. The temperature is relatively low in winter, so it's better to move him into the room for maintenance. The temperature is about 11 degrees, and it's 5 to 10 degrees at night. Pay attention to ventilation during indoor maintenance, and the humidity should not be too high. The temperature is too high in summer. Don't be burned by the sun. Keep the temperature below 28 ℃.
Do not apply too much concentrated fertilizer to orchids. Use liquid fertilizer or foliar fertilizer. In the period of vigorous growth, you can apply a half month to 20 days of rotten cake fertilizer water, which is also thin fertilizer. Because the root system of orchid is special, it is succulent root, in order to avoid rotten root, the fertilizer that applies should go through putrefaction..
