Orchid growth not only requires sufficient light and the right amount of moisture, but also a good ventilation environment. Ventilation is not only a requirement for orchid living habits, but also promotes the respiration, photosynthesis and transpiration of orchids, and strengthens the metabolism of orchids. In addition, ventilation can also effectively regulate the temperature and humidity of orchid breeding sites, and curb the reproduction and harm of fungi and insects. However, ventilation also requires a certain amount of skill, otherwise it can backfire. Here are a few points to note for orchid ventilation.
1. Choose the right pot
To truly meet the ventilation requirements of the festive orchid, you first need to choose the right pot. Orchids prefer a hydrophobic and breathable environment, so the choice of pots is crucial. It is recommended to use a pottery pot with a hydrophobic and breathable bottom and a porous bottom edge. Such pots ensure the permeability of the root system and avoid root rot caused by stagnant water. At the same time, the material of the pottery pot itself also helps to regulate the temperature and humidity in the pot, providing a stable growth environment for the orchid.
2. Use a loose and breathable matrix
In addition to pots, the choice of substrate is also crucial. The root system of the orchid needs a loose and breathable environment to be able to breathe freely. Therefore, it is recommended to use loose and breathable substrates such as perlite, volcanic stone, pine bark, coconut shell, grass charcoal, etc. These substrates not only provide good air permeability, but also maintain moderate humidity to prevent the roots from being too dry or too wet, which I used to grow with Matsuragi King 1:1 mixed volcanic stone.
3. Set up hydrophobic breathable hoods and catheters
In the process of orchid maintenance, the effect of ventilation can also be further improved by setting up a hydrophobic vent hood and a conduit. A hydrophobic vent can create a small environment around the orchid, both to maintain humidity and to ensure air circulation. Catheters can help drain excess water and avoid root problems caused by standing water. These auxiliary measures can better meet the needs of orchids for ventilation.
Fourth, the orchid pot display is sparse
The ventilation of orchids requires not only efforts from the pot and substrate, but also the placement of the orchid pot. The display of orchid pots should not be too dense, and a certain distance should be maintained so that the air can circulate freely. Too dense placement will affect air flow, resulting in increased local humidity, which can easily breed germs and pests. Therefore, the distance between the orchid pots should be kept at least 10 cm to ensure that each orchid can be well ventilated.
Fifth, I like the gentle wind
Although orchids like the wind, the stronger the wind, the better. Orchids like the gentle breeze, that is, the wind that makes the leaves of the orchid tremble slightly. Excessive wind not only tends to blow the orchid leaves, but also causes the leaves to rub against each other, causing mechanical damage. These injuries provide an opportunity for germs and viruses to invade and therefore need to be avoided. In the case of strong winds, the orchid can be protected by setting up a wind shield or moving indoors.
6. Adjust temperature and humidity
Ventilation can not only regulate temperature and humidity, but also effectively curb the reproduction and harm of bacteria and insects. Orchids have different needs for temperature and humidity in different seasons. Spring and autumn are the peak months for orchid growth, and it is necessary to maintain a high humidity at this time, but at the same time, it is necessary to pay attention to ventilation and ventilation to avoid diseases caused by excessive humidity. In summer, when the temperature is high, it is necessary to appropriately reduce the humidity and strengthen ventilation to avoid the occurrence of diseases in the high temperature and high humidity environment, but be careful not to affect the growth of orchids due to too dryness. In winter, it is necessary to maintain a low humidity, but also pay attention to ventilation to avoid frost damage caused by low temperatures and high humidity.
7. Avoid mechanical damage
While ventilating, care is also needed to avoid mechanical damage. Orchid leaves are fragile and susceptible to external factors. When placing orchids, the leaves should be avoided from contact with other objects, especially hard objects, to avoid damage to the leaves. At the same time, friction between the orchid leaves should also be minimized, which can be achieved by properly pruning the leaves or adjusting the distance between the orchids.
8. Regular inspection and maintenance
In order to ensure that the orchid is always well ventilated, it is also necessary to carry out regular inspection and maintenance. Regularly check whether the pot is blocked or damaged, whether the substrate is loose and breathable, and whether the ventilation hood and conduit are unobstructed. If there is a problem, it should be repaired or replaced in time. At the same time, regularly clean up fallen leaves and dead branches to avoid the breeding of germs and pests.
