Fertilize the orchids on the balcony

Orchids originally grow in mountains and forests and rely on nature for nourishment. After entering the house, we have to rely on manual supply. Some people think that orchids can grow without fertilization, which depends on the specific situation. If orchids are rich in mud, they can not be fertilized for a period of time, but not for a long time, especially hard plants need timely fertilization. Orchids can be planted without fertilization, but they cannot be planted well and it is difficult to make them blossom. Fertilization is not the more the better, heavy fertilizer will cause fertilizer damage, affecting the growth of orchids.

Fertilization should be reasonably matched according to the growth of orchids, promote leaf bud growth mainly by nitrogen fertilizer, promote root development and flower bud development by phosphate fertilizer, maintain plant health and increase disease resistance mainly by potassium fertilizer. Other elements such as calcium, magnesium, sulfur and iron should also be replenished at the right time. Some people think that summer and winter should stop fertilization, in fact, summer orchid is the period of seedling and long leaves, and the temperature is high and nutrient consumption is much, so it needs nutritional supplement very much. In winter, orchid plants seem to be dormant and stop growing. in fact, orchids are still growing in warm rooms, even vegetative growth has not stopped completely, so fertilization can not be completely stopped.

Fertilizer can be divided into organic fertilizer and inorganic fertilizer, organic fertilizer such as bean cake, bone meal, rice bran water, fish viscera, etc., should be fully fermented, and then diluted application. Its advantage is sufficient fertility, long fertilizer effect, but there is a bad smell, such as poor disinfection, but also easy to bring germs. Inorganic fertilizer referred to as chemical fertilizer, easy to use, no fat odor. In order to keep the environment clean, it is better to apply chemical fertilizer to raise orchids on the balcony. There are many kinds of chemical fertilizers. I often use Huabao, Orchid King, Flower Root Wang and so on. Using the method of applying thin fertilizer frequently, once every seven days to half a month, the effect is better.
