How to promote orchid blooming

First, light. Light is the main factor to promote the bud formation of orchid plants. The intensity of light varies greatly with different species of orchids. In general, when flower buds are being formed, if the orchid plant is put under bright light, the red, dark red and yellow colors will deepen when flowering. For orchid plants with green or white flowers, the light intensity should be reduced as soon as possible when the bud appears, so as to ensure that the color of the flowers is more elegant, and then re-give more light after flowering. In general, orchids need 2 to 3 hours of light. The leaves are soft and moderately green, indicating normal light. The leaves are dark green and soft, indicating the need for more light, while the yellowish leaves mean less light.

Second, temperature. To promote orchid blossom, it is necessary to make the temperature difference between day and night about 10 degrees Celsius, that is, the temperature of 18 to 21 degrees Celsius during the day and 7 to 10 degrees Celsius at night grows best and blossoms more. When the temperature is high at night, the leaves of the orchid plant will be soft and the flower buds will fall off. Too low temperature can cause blind buds and spots on the leaves. The flowers show brown spots when they are damaged by low temperature when they bloom.

Third, watering. The amount of watering is also the main condition for orchid flowering, and the moisture should be well controlled. If there is too much water, the orchid plant will grow and it is not easy to grow buds. Proper moisture is one of the ways to promote blooming. However, due to the lack of water, the phenomenon of clamping will occur in order to work.
