Using a few tricks to raise orchids under high temperature can be the icing on the cake.

In July every year, most cities in the country are between 30 and 35 ℃, and very few areas have a high temperature of 35 to 40 ℃ in a short period of time. Such temperatures generally last until the end of August, and there will be autumn tiger weather of more than 30 ℃ in the first ten days of September. So, how can it be the icing on the cake to raise orchids under high temperature? We need to make good use of these tricks.

In fact, flower friends raise orchids in hot weather and use several tricks to fertilize orchids in the hot season, which can add to the icing on the cake.

1. Fertilization method in high temperature season.

Orchids need to be replenished with nutrients in the hot season and vary with temperature, so skillful fertilization has become the key in this season. From late June to early September every year, although it belongs to the high temperature season, the daily temperature is changing, cool in the morning and high in the day. The high temperature season is also the high incidence period of thunderstorms, and we can choose to use all available space to fertilize in the evening or when it is cool in cloudy and rainy days.

As the weather is changeable in this season, in order to prevent the unpredictable high temperature from coming the next day after fertilization, we must keep in mind that we must increase the amount of water when using it, for example, 500 times the organic liquid fertilizer for orchids is usually used. now it needs 800 times liquid; it is usually once every seven days, but now it is once every half a month.

2. Fertilizer selection in high temperature season

We are very particular about choosing the kinds of fertilizers. Considering that the conversion function of orchid plants in high temperature is weakened, but its absorption function is not weakened with the advent of high temperature, on the contrary, the absorption function is enhanced when transpiration is increased, and fertilizers that are convenient for direct absorption can be selected. such as organic liquid fertilizer for orchids.

This kind of fertilizer belongs to quick-acting organic fertilizer, which can be absorbed and utilized within 1 hour, and the remaining organic fertilizer beyond 10 hours is very difficult to produce fertilizer damage. We have enough safe time to fertilize in the evening or when it is cool and cloudy. However, it should be noted that the concentration is not too high.

If flower friends like homemade organic fertilizer, it is not recommended to use it in high temperature season because it is difficult to determine. Granular organic fertilizer and inorganic fertilizer are not recommended in high temperature season because of their concentrated release.

3. Fertilization objects in high temperature season

The fertilization target should be clear in the high temperature season. Weak grass and diseased grass should be applied cautiously because of their poor root system and poor conversion and absorption function. In that year, the orchid using organic matter plant material, because its plant material is rich in organic components, accelerated decomposition and release in high temperature season can meet the needs of orchids for nutrients, so there is no need to apply fertilizer.

The main targets of fertilization are strong plants and orchids that have not been turned over for more than a year to replace new plants or use soilless cultivation. At this time, clever fertilization can achieve the purpose of strengthening grass in autumn, and at the same time, it will also play a positive role in the cultivation of the second and third generation buds. In addition, good use of summer fertilizer for orchids of flowering age can promote the growth of buds.
