You need to read in advance to raise orchids in the second hot month in August.

August is coming, which means that a new round of high temperatures is coming. Raising orchids this month is still facing a high temperature crisis, so florists want orchids to get through August smoothly, and some skills for raising orchids in August should be read in advance.

1. There are two seasons this month, the Beginning of Autumn (7-9) and the End of Heat (22-24). The monthly average temperature is similar to that of the previous month, still about 29 ℃. The weather is extremely hot, which is the second high temperature month of the year. The main work is still shading. Close curtains are still used when the temperature is more than 25 ℃. If the temperature is below 25 ℃, a sparse curtain can be used to prevent orchids from being exposed to direct sunlight. Indoor orchids pay attention to ventilation, heat prevention and cooling.

2. Strengthening the ventilation of orchid houses is still the focus of this month's work. Windows should be opened, exhaust fans should be always open, wall fans and ceiling fans should be opened all day to ensure that the air in the orchid room is fresh and can effectively restrain the reproduction of germs, which is a work that can not be ignored.

3. After the Beginning of Autumn, the air humidity decreases, and the water supply is very important. We should water more appropriately and keep in mind the warning of "don't dry in autumn". Especially when there is no rain for a long time, pay attention to watering and moisturizing. If the humidity is too low, you can spray water or spray to the ground to ensure the humidity of the orchid room, prevent the orchid from shrinking leaves and withered tips, and ensure that the orchids thrive.

4. The orchid plant consumes a lot of nutrients in the basin after the high temperature and heat in summer. From mid to late August, it is necessary to apply the common organic fertilizer for orchids once every 10 days, diluted by 500 times, and foliar fertilization once every 10 days, the two can be carried out alternately and diluted 1000 times.

In addition, fertilization in August should appropriately increase the composition of phosphorus and potassium to facilitate the production of flower buds. 0.5% potassium dihydrogen phosphate can be used alternately with organic liquid fertilizer commonly used in orchids, while ensuring the growth of autumn buds and the breeding of strong early spring buds. However, the fertilizer should be thin, and the thick fertilizer should not be applied, and the time should still be carried out in the sunny evening when the temperature is lower than 30 ℃ after the plant in the orchid basin is slightly dry, and the next morning it needs to be watered with "reviving water".

Typhoons often hit in May and August, and flower friends should also do a good job in preventing typhoons from overturning orchid pots and breaking orchid leaves. It is windless and hot after the typhoon, so it is necessary to repair the sunshade net damaged by the typhoon in time to prevent orchids from being burned by the scorching sun.

6. It is not suitable to change the basin, divide the plants and introduce varieties this month. This month ramet, the wound of bluegrass is easy to be infected with germs, it is dangerous, and the old grass is easy to fall out, flower friends should pay attention.
