I heard for the first time that Dendrobium can keep fit. In fact, Dendrobium flowers are particularly beautiful, even more beautiful than orchids. Many friends like to raise Dendrobium because they like to watch it bloom. In fact, Dendrobium is not very beautiful, and its maintenance and shape are similar to orchids. 1. The root system of Dendrobium is very thick for flowerpots. The flowerpot should be made of purple clay pot or clay pot with good water permeability as far as possible, and it can also be parasitized and maintained with wood and stones. Rotten pine bark can be used as pot soil, and thicker bark has stronger water-locking function. When watering, you can lock some water, and the excess water will not accumulate when it seeps out. Then some large particles are added to the basin soil, so that the roots can be restrained on it and attached to it, thus stabilizing the effect ratio. 2. The original environment of Dendrobium candidum is in a humid mountainous area, and epiphytes are attached to trees, so I like an environment with sufficient scattered light or semi-shade, and I can't direct strong light, otherwise the leaves will turn yellow and fall off easily. 3. Dendrobium nobile likes the environment with high air humidity, and its growth temperature is between 15-25 degrees. If you put Dendrobium in a humid environment as much as possible, spray it once a day to increase the humidity of the air. 4. Fertilization Dendrobium also needs fertilization during the growth period, because its root system is relatively strong and it can supplement liquid fertilizer two or three times a month. If the elements of nitrogen, phosphorus and potassium are complete, they can be sprayed on the leaves according to the ratio of 1: 1000. You can also water it, and put a little dry manure or dry cow dung in the flowerpot to increase nutrition. Some Dendrobium can bloom continuously all year round, so it is necessary to spray phosphorus and potassium fertilizer on the leaves frequently to promote flowering.
