How to raise orchids? First of all, we should understand the growth habits of orchids.

If we want to raise orchids well, we must first understand its growth habits. As long as people who have picked orchids on the mountain have paid attention to the surrounding environment, then we can understand the growth habits of orchids.

The ancients made an accurate summary of the growth habits of orchids:

Happy moist but afraid of dampness; like light but afraid of exposure; like warmth but afraid of heat; like ventilation and afraid of wild blowing.

Specifically, there are the following points that need to be noted:

1. Orchids need sunlight to grow, but scattered light, not direct exposure, and we can't do that either. Full sunshine can be accepted in winter, shade in summer and semi-shade in spring and autumn. Different varieties of orchids require different degrees of shade. 60% for Jianlan, 70% for Chunlan, 70% for Cymbidium, and 85% for Cymbidium. When the sun is too strong, the orchid leaves are yellow, and when the sunlight is insufficient, the orchid leaves are dark green.

2. At what temperature does orchid grow rapidly? Spring orchids grow very fast when the temperature is between 15 and 25 degrees Celsius, Jianlan, 25 to 30 degrees Celsius, and ink orchids 20 to 30 degrees Celsius. If the temperature is too low or too high, orchids may stop growing. In general, orchids grow below 10 degrees and above 40 degrees Celsius. Stop growing.

3. Orchids like fresh air, which is a common feature of all plants. Orchids also like orchids, and the air humidity is very high. Afraid of dryness, the best air relative humidity is 70-85%, Jianlan and Hanlan can be slightly dry, and Chunlan can be slightly moist.

4. Orchids like planting materials, that is, the things we put in the basin are not dry, but they are afraid of stagnant water and are prone to accidents if they are blistered for a long time, so the treatment should have good ventilation and smooth drainage, otherwise, when you turn the basin, you will find, why? Why is the orchid root broken?

These provide a basis for us to raise orchids scientifically, but in practice, we should grasp them flexibly according to different regions, different seasons, different climates and different orchid varieties.
