Orchid Management in July

The most important thing in rainy season and hot summer is watering environment management. the most important point in summer environmental management is cooling. In temperature management, artificial cooling is limited. But because it is the rainy season, the temperature will not rise too high this month. The problem is that the occasional sun raises the temperature inside the orchid room. The shading rate should be set to more than 60%, and it is important to open all the windows so that the orchid is not exposed to a sudden rise in heat. For the balcony orchid room of the building where it is difficult to assemble the sunshade material, it should be completely open to cover only the orchid without the window where the sunshade material can be installed. Just shading is not enough, but also do a good job of ventilation. Ventilation can use devices such as blowers or fans, but use skylights and windows for natural ventilation as much as possible. You can also often sprinkle water on the floor of the orchid room to reduce the temperature by evaporating water. In view of the tropical night phenomenon that begins in the last ten days after the end of the rainy season, the water in the basin should be drained as far as possible. Slightly reduce the amount of water, after watering must be ventilated. Nutrition management during this period, the temperature is mainly high temperature and humidity, so basically no fertilization, but have to consider the growth of new buds. At this time, there is no real fertilization, just foliar fertilization, which can be regarded as the supply of nutrients. Foliar fertilization, as far as possible in cloudy days or evening, the concentration should be lower than usual, and often fertilize. But when the rainy season is over, it is safe not to apply fertilizer. Prevention of diseases and insect pests this is the most likely period of occurrence of diseases and insect pests. First of all, the reproduction of pests such as slug and shield scale is very vigorous. In particular, the slug must pay attention to it, it will eat the new buds. Slugs hide in dark, damp places during the day and are hard to find. When it comes out at night, turn on the flash to observe, and it is easy to find slugs around the orchid basin. If there were insect pests last year, they will also occur this year, so we must pay attention to them. On the contrary, shield scale is mostly found in dry and hot environment. It mainly sucks juice around the dorsal bone, and spraying does not work, so you should pay attention to killing it. Secondly, corruption and soft rot are the representative spots in summer. For example, corruption only hurts new buds, but soft rot can spread to the whole orchid, with fatal consequences. Keep in mind that these symptoms are hard to find in healthy orchids or orchids that are normally watered. Usually, watering and environmental management should be done thoroughly to prevent these pathogens from infecting orchids.
