Orchids like semi overcast environment. They need good shade in spring and summer to grow normally. They are afraid of strong sunlight. If the light is too strong, it will affect the absorption of water and normal metabolism. However, sunlight is the basis for the synthesis of nutrients. In autumn and winter, we need to supplement enough sunlight, which can be put in a better place.
It is suitable for growing in slightly acid sandy soil, rich in humus, with sufficient nutrients, with overall permeability and good drainage effect, so the special orchid soil is very suitable.
Temperature control is an important factor in keeping orchids well. The most suitable temperature for growth is about 20-28 ℃. It can't stand the cold. It's better to control the temperature of overwintering at about 10 ℃, not too low.
There are many factors for applying water. If the surrounding temperature is low, less water can be poured properly, and more water can be poured when the temperature is high and evaporation is fast in summer. It is also necessary to consider the size of basin soil and the state of plant growth, and water according to the specific situation.
Spring and summer and autumn are two periods of vigorous growth. More fertilizer can be applied once a week to ensure. From the beginning of autumn and winter, the growth is gradually slow, so we should apply less fertilizer.
