4 ways to cool down orchids' "internal heat" so they bloom all summer long
Summer is hot, and orchids enter the most difficult growing season of the year. How to reduce their "internal heat" and lower the temperature so orchids safely make it through summer is the issue flower lovers care about most. Given the hot, dry characteristics of summer temperatures, flower lovers can use the following 4 methods to cool down the orchids' "internal heat," and they will bloom all summer long.
1. Shade and cooling
Summer sunlight is extremely intense. Flower lovers can use double-layer shade nets to provide shade, increasing the shade density of the orchid-growing environment and reducing light intensity and water evaporation, so as to keep the environment cool.
2. Evaporative cooling
The evaporation of water can absorb a large amount of heat from the air and increase air humidity, which not only lowers the ambient temperature but also increases air humidity for the orchids' growth needs and promotes photosynthesis.
If you have a dedicated orchid room for care, flower lovers can use a misting device indoors to cool with water mist, or use a spray bottle to wet the floor and surrounding walls of the orchid room, achieving a cooling effect through water evaporation. In the orchid room, you can also use the method of setting up a water trough to store water and lower the temperature inside the orchid room.
3. Ventilation and cooling
Strengthening ventilation in the orchid-growing environment can produce a very good cooling effect. On summer afternoons, the temperature inside an orchid room is usually extremely high and very stuffy. Orchids will stop growing because of this, close their stomata, stop respiration and photosynthesis, and enter a temporary dormancy.
High temperature and high humidity also easily cause pathogens to multiply in large numbers. Therefore, strengthening ventilation in the orchid room not only has a cooling effect but also prevents pathogens from multiplying in large numbers under high temperature and high humidity, maintains the orchids' photosynthesis, and enhances the orchids' resistance.
When caring for orchids normally, also pay attention to replenishing nutrients for the orchids in time, and improve the orchids' disease resistance through the accumulation of nutrients. It is generally recommended that flower lovers use an organic nutrient solution specially made for orchids, diluted with water at 500 times and poured at the roots. In summer, orchids that are still in their growth period can all use it. Diluted according to the ratio, it will not cause root burn.
4. Air conditioning cooling
In addition, orchid enthusiasts who have the conditions can use air conditioning to cool down, keeping the orchid room always at a temperature suitable for orchid growth and extending the orchids' growth period. When using air conditioning to cool down, keep the day-night temperature difference at around 10°C to maintain the orchids' normal metabolism.
