Planting orchids is a skill. Live fertilization pays more attention to the knowledge of fertilization in four seasons.

Orchids have always been known as a gentleman in flowers, many flower friends like to plant orchids, orchids give people a very quiet feeling, especially in the study put a pot of orchids, feel that the whole study environment has become quiet. But orchids are also notoriously difficult to raise. Here I will talk to you about the fertilization of orchids.

Spring fertilization

Friends who grow orchids all know that it is difficult to raise orchids in spring, the temperature in spring is gradually rising, everything is recovering, and orchids are also gradually recovering. At this time, flower friends should not worry about fertilizing orchids. They should wait until the temperature rises to about 18 degrees before they start fertilizing orchids. Fertilization also needs to consider the weather, plant materials and other issues.

When the weather temperature is relatively low, fertilization must be thin and not too thick. generally, it is combined with watering, and the concentration of fertilizer is about 1/8 of the usual concentration. Foliar fertilizer should also be light, generally 1/5 of the usual concentration on it. This is conducive to orchid sprouting.

In addition, we need to consider the temperature and weather. Because the temperature changes greatly in spring, if it rains continuously, fertilization can be carried out in the morning or evening. If the temperature is relatively low, it is best to do it when the temperature is high in the afternoon. Fertilizer is generally the frequency of balanced nitrogen, phosphorus and potassium fertilizer every ten days or so.

Summer fertilization

Raising orchids is really a very difficult thing, the summer temperature is relatively high, and hot and humid, orchids are very easy to get sick, but it is also the best season for orchids to grow. So fertilizing orchids in summer is also a very fastidious thing. Summer temperature is relatively high, and evaporation is more exuberant, fertilization should be light, not too thick, otherwise it is easy to lead to orchid fertilizer damage and root burning.

The foliar fertilizer of orchid is mainly used in summer. 1/1000 potassium dihydrogen phosphate and urea of the same concentration can be used to spray the foliage of orchid, which should be sprayed in the evening, and then sprayed with water the next morning. Root topdressing is mainly nitrogen, phosphorus and potassium fertilizer, while paying attention to add some other trace elements, fertilizer must be light, generally 1/20 of the usual appearance.

If you encounter plum rain, it is best to wait until sunny evening before fertilizing, and then water the orchid the next morning to avoid fertilizer damage. Every two weeks to twenty days. When the temperature is too high, generally more than 35 degrees will stop fertilizing, to avoid orchid fertilizer damage.

Autumn fertilization

As the temperature drops in autumn, the growth of orchids has entered a slow period, when the most important thing for orchids is to raise roots. Some orchids will enter the flowering stage in autumn, so autumn fertilization should not only pay attention to the frequent application of thin fertilizer, but also pay attention to more phosphorus and potassium fertilizer, less or not nitrogen fertilizer, avoid the excessive growth of orchid flowers and leaves, promote the differentiation of orchid flowers and leaves, and gestate buds. More blossoms.

Winter fertilization

In winter, most orchids have entered a dormant period and stopped growing. Only some orchids will grow, such as winter orchid and cold orchid, but this is only a special case. After entering the dormant period in winter, most orchids will stop fertilizing, otherwise it will easily lead to damage to the roots of orchids, blackening and decay.

The above comes from promoting agriculture through science.
