Have you ever been attracted by the elegant fragrance of orchids, but have suffered repeated setbacks in the process of breeding? Why are your orchids always in poor condition, with yellow leaves, or even slow to bloom? Don't worry, today we will reveal the core point of orchid farming - ventilation, to help you become an orchid farmer!
First, let's talk about why ventilation is so important for orchids. Not only do the leaves of the orchid need to breathe, but its root system also needs to breathe, so it is called "aerial root". In an environment with poor air circulation, it is difficult for the root system of orchids to get the necessary oxygen, and growth will naturally be affected. Therefore, ensuring good ventilation is the first step in raising a good orchid.
So, what kind of ventilation is needed for an orchid, is it windy or breezy? The answer is the latter. Orchids prefer soft, windy winds, just like in nature, they are always shaded by other plants or objects and are not directly exposed to strong winds. Therefore, when cultivating orchids, we try to avoid direct, strong winds.
In addition to the softness of the wind, the source of the wind is also important. The winds formed by warm and cold air and wet and dry air are particularly beneficial for orchid growth. For example, in the shade of a tree or by a stream, a light breeze naturally forms due to differences in temperature or humidity, which is very conducive to the growth of orchids. If you can simulate such an environment, your orchid is sure to thrive.
In addition, wind direction is also an important factor affecting the growth of orchids. Orchids prefer southeasterly winds, which are usually warm and humid, which is conducive to the growth and flowering of orchids. On the contrary, the cold and dry northwest wind is not conducive to the growth of orchids. Therefore, when placing orchids, try to make them as able to blow the southeast wind.
Speaking of which, some people may ask: since ventilation is so important, shouldn't I just use an electric fan to blow the orchid? Although electric fans can produce wind, this straight wind is not to the liking of orchids. Straight wind can easily cause yellowing of the focal tips of the leaves, and even cause mechanical damage to the orchid leaves. Therefore, when we cultivate orchids, we should try to avoid using electric fans and other equipment that generates direct air.
So, how do you make sure your orchids are well ventilated? First, choose a well-ventilated place to place your orchids, such as near a window or balcony. Secondly, you can open the windows regularly for ventilation to allow fresh air to circulate. Finally, pay attention to the density of the orchids and do not overcrowd them, so as not to affect the ventilation effect.
