Orchid management in August

Extreme heat and tropical nights require shading and ventilation environmental management the hot summer and tropical nights that begin after the end of the rainy season are the most difficult months for many Ailan people to manage orchids. But as long as you block out the direct light and open all the windows for ventilation, you can spend the summer safely. You'd better open the skylight, too. In this way, hot air is naturally discharged from the skylight and fresh air flows in. By using this method, the indoor temperature can be 2-3 degrees lower than that outside. When using electric fans, blowers and other equipment, it should be noted that excessive blowing will make the orchid leaves rough. Increase the shading rate as much as possible to darken the orchid room. If the orchid room is on the ground and the ceiling has some leeway, you can add a sunscreen film indoors. If the orchid room is located in the building, keep the orchid shelf away from the window as far as possible, with an additional curtain on the curtain. At this time, the shading material must be fixed to avoid the curtain touching the blue leaf when the wind is blowing. Orchids are rarely injured by the heat if they are well ventilated in the shade. Orchids that grow taller in the rainy season become stronger, and new buds that are not growing well grow as much as possible. Watering management at this time, the main reason for orchid injury is watering. Usually wait for the makeup soil to dry in the evening before fully watering. After watering, open all the windows for ventilation, and use electric fans and blowers to blow weak wind. Use cotton swabs and brushes to remove excess moisture from soaking new buds. Orchids can also be managed with peace of mind during the hot summer periods, which last at night and are hot during the day. If it is forced to lower the temperature or worry too much about the drying of the orchid basin, pouring too much water on the orchid will hurt the orchid. When there is a cool breeze in the morning and evening after the middle of the year, you can return to normal watering. The orchid pot that is normally watered in summer dries naturally, the root of the orchid also has vitality, and the flower bud differentiation is also very good. Nutrition management orchids grow actively this month, and exuberant breathing activity is formed as the night temperature rises. In theory, the nutrition of orchids should be increased at this time, but in fact, many Ailan people consider the side effects of extreme heat and do not apply fertilizer. During this period, when the rain and temperature drop, you should choose active agents or fertilizers that can be fertilized on the foliar surface. At this time, it must be noted that choose cloudy or rainy evening or night, when the wind is low. When there is a strong wind, you need to close the window and re-fertilize. When spraying in the air with a sprayer, the amount of fertilizer applied is based on the fact that there are no water droplets on the leaf surface. To prevent diseases and insect pests in summer, the greatest harm to orchids is the injury of new buds caused by excessive humidity in flowerpots, and even develops into soft rot, injuring the whole pot of orchids. In addition, there is the phenomenon of aging from the outer leaves of the old seedlings. Pests can invade new buds. Far from the city, the new buds of orchids are also eaten by rodents and insects. The excessive dampness of the flowerpot is caused by overwatering at once. If the orchid itself does not grow well, or if the roots are watered normally, it will also hurt the orchid, so usually pay more attention to observe the orchid basin to see if there is anything abnormal. If there is an orchid basin with uneven drying of cosmetic soil, the number of watering can be reduced. It is normal that the leaves of orchids have aged for more than 5 years. However, if the leaves of orchids that have not been long for a long time turn yellow and gradually dry into brown, they should be carefully checked to see if there is a problem with management. Under the condition of hot weather and excessive consumption of nutrients, it is easy to appear the aging phenomenon in the early stage, and the sudden increase in the amount of daylighting will also appear. In particular, the orchid room of the building is different from the early summer, there are some changes in the period of sunlight in the second half of the month, and sometimes there will be sudden exposure to the sun. Therefore, you should check the time period of sunlight at any time to avoid direct sunlight.
