How to grow orchids in hot summer?

Chinese orchids like soft sunlight and hate direct sunlight; they like a cool, dry and ventilated environment and are afraid of humid and hot places. Although orchid grass is afraid of sultry heat, it is not afraid of high temperatures, because high temperatures can induce the leaves of orchid grass to thicken, enhance the toughness of orchid grass growth, and thus improve the adaptability of orchid grass itself to the environment. The ancient Yilan seniors and Laolan people in Jiangsu and Zhejiang areas often practice in the summer of dog days. Grass, we are well versed in the habits of orchid grass. In hot summer, we keep orchid grass a little dry and not too humid. On the one hand, we can avoid the soft rot and stem rot caused by high temperature and high humidity, and on the other hand, we can control the water. Prompt the orchid grass to differentiate into flower buds, accumulate nutrients, and form autumn buds and flower buds in autumn.

For the planting and management of orchids in summer, there are roughly the following aspects that we need to pay attention to:

1. Pay attention to the ventilation of the orchid site: when growing indoors, open all indoor windows. , to allow the air to fully convection, and you can also use a fan to discharge the hot air to ensure that the indoor air is fully convection. In this way, even if the temperature in the orchid room is higher than 35℃~40℃, there is no need to worry about falling grass. But one thing you must pay attention to is that the orchid cannot be exposed to direct sunlight and needs to be shaded and cooled.

2. Keep the orchid site dry: Many novice orchid lovers are worried about the damage caused by the high temperature in summer to the orchids. They like to spray water on the leaves of orchids or use humidification equipment to increase the humidity of the site and achieve cooling. The result is black spots on orchid leaves or even soft rot. Although the temperature is high in summer, the humidity is also relatively higher than in other seasons. If the relative humidity of the orchid house is blindly increased, the high temperature and high humidity will make the orchid house a place for rapid breeding and reproduction of various germs. When the air ventilation is not good, Due to transpiration, orchids are prone to disease and death. Moreover, I personally think that the humidity required by orchid grass is not necessarily the relative humidity in the environment, but the absolute humidity in the orchid pot where the orchid grass grows. Therefore, keeping the orchid room or orchid raising place dry is definitely the best way to help orchid grass survive the hot summer. Important key.

3. Strictly control the timing of watering: Summer is the period when orchid grass grows rejuvenated and flower buds differentiate. During this period, watering of orchid grass must be strictly controlled. During the day, the temperature is too high and the planting material is not dry. Watering should be done in the evening or evening when the temperature is slightly lower, because orchid grass will gradually enter a semi-dormant state when the temperature is higher than 30°C. If water is given at this time, the orchid grass will not be able to absorb it and will instead become waterlogged. In the orchid pot, the orchid roots can fester and become hollow, which can easily lead to soft rot and stem rot, leading to irreparable losses. In addition, strict water control in the summer to keep the orchid pot slightly dry can induce The orchid grass itself generates a sense of crisis and promotes the differentiation of flower buds. Therefore, strict control of water supply and watering timing in hot summer is an important issue in summer orchid grass management.
