It is generally a mixture of several media, such as a mixture of small stones, bark, coconut shells, bark, slag, etc., or a mixture of humus soil, peat soil, etc.

Watering Tips

Orchids have a better water storage capacity and consume less water, so they are more drought-resistant. However, orchids have a relatively large demand for water when growing, and watering needs to be adjusted according to the orchid's growing environment and growth conditions.

When the temperature is high, the evaporation is large, so you need to water more, but if the temperature is low, water less. The second thing is light. If there is plenty of sunlight, watering is also necessary. In addition, orchids like rain but fear waterlogging, like moisture but fear humidity. When the weather changes, you should follow the principle of watering more on sunny days, less on cloudy days, and no watering on rainy days.

Basically, when watering, you should adhere to the principle of watering thoroughly and water frequently, but make sure that there is no water accumulation in the soil.

Fertilization tips

Fertilization is very important for plant growth. For orchids, there are many fertilizers to choose from. Well-rotted farmyard manure or special flower fertilizer are both good choices. However, when fertilizing orchids, you must follow the principle of applying thin fertilizers frequently. Basically, apply thin liquid fertilizer every 10 to 15 days, and spray foliar fertilizer from time to time.

Light and temperature

Orchids are shade-loving plants and are relatively afraid of sunlight, but light is also essential for their growth.

During the winter, orchids need full sun. In the summer when the light is strong, orchids need to be shaded. During the day, the morning sunlight is best for orchids because the light is softer at this time, will not burn the orchids, and is more conducive to orchids' photosynthesis. Therefore, it can be exposed to direct sunlight before 7 o'clock in the summer, and needs to be shaded afterwards.

In the actual operation of orchid cultivation, just adjust the light according to the orchid's requirements for light.

The best growth temperature for orchids is between 18 and 30°C. If it is above 35°C and below 5°C, the growth of orchids will slow down. Therefore, orchids should be kept indoors during the winter.

When planting orchids, you should try to choose a spacious and high place that is conducive to ventilation. If you are in a closed room, open the windows frequently for ventilation and be careful not to plant indoor plants too densely.
