Dendrobium is suitable for growing in warm and humid environment, which requires sufficient water and high air humidity. However, it has special requirements for substrate, usually growing in bark, trunk and stone seam. Due to its growth habit, many kinds of plants are planted in the south, and the North needs to provide better growth conditions for maintenance.
1. Matrix selection: Dendrobium has special requirements for matrix. It can't grow in the soil and needs to be configured with bark and sawdust. Generally, the bark of the tree is Jue, pear and camphor. It can also be planted on stone, but there should be moss on the surface.
2. Moderate light: the growth environment of Dendrobium should not be too cloudy or too dry. Too long light is easy to cause its leaves to burn and its stem to turn white, but the absence of light is not conducive to its growth. Can be properly shaded, so that it receives a certain amount of astigmatism.
3. Humidity control: Dendrobium has higher requirements on humidity. Environmental drying is not good for its growth. It is necessary to keep the substrate moist at all times, and at the same time, there should be water in the air. Can regularly spray water to improve humidity, watering should not be more frequent.
4. Reasonable fertilization: the field planted Dendrobium should not be fertilized too much, just twice a year. For the first time in Qingming Festival, nitrogen fertilizer was used to mix animal manure with river mud. For the second time, the river mud was mixed with superphosphate before and after the beginning of winter. Potted words should be according to plant growth situation topdressing, general flowering before the use of phosphorus and potassium fertilizer.
