Culture skills of Dendrobium

Dendrobium, along with Cartland, Phalaenopsis and Wandai Orchid, are the four major tropical ornamental orchids, which is one of the largest genera in Orchidaceae. According to its biological characteristics and different ecological requirements, it can be divided into two categories: deciduous Dendrobium and evergreen Dendrobium.

There are many varieties of Dendrobium. At present, the common ornamental cultivation are Dendrobium candidum, Dendrobium candidum, Butterfly Dendrobium, Dendrobium nobile, Dendrobium candidum, Dendrobium candidum, Dendrobium candidum and so on. Dendrobium is an important variety of cut flowers and potted plants because of its beautiful flower shape and beautiful appearance.

In order to raise Dendrobium well, we can start from the following aspects:

Block out the light. Dendrobium often grows on tree trunks or rocks in tropical rain forests in its place of origin and prefers semi-shady environment. During the peak growth period in spring and summer, the sun can be shaded by 60% Mel 70%, but more sunlight is needed during the winter dormancy period. Generally, it can be shaded by 20% Mel 30%, or not.

Keep warm. Dendrobium likes high temperature and humidity. The overwintering temperature of deciduous Dendrobium can be as low as 10 ℃ or lower at night, while that of evergreen species should not be lower than 15 ℃. At the same time, attention should be paid to maintaining a large temperature difference between day and night (10-15 ℃). Too small temperature difference will seriously affect the growth and flowering of Dendrobium.

Water properly. Dendrobium orchid needs plenty of water, but avoid being too wet, which will lead to poor plant growth, rotten roots and even death. Deciduous Dendrobium can be kept dry and watered less in winter, but the air humidity of potted materials should not be too low. Evergreen species need to keep plenty of water if the greenhouse temperature is high in winter.

I spray a lot. In the sunny, dry and hot growing season, water should often be sprayed around the plant to increase air humidity. High humidity in the rainy season, you can stop spraying and be careful not to let the flowerpot accumulate water.

adequate manuring. Dendrobium likes to apply thin fertilizer frequently, applying mature cake fertilizer and water every 7-10 days during the growth period, or 0.1% all-element compound fertilizer outside the root. When deciduous species are dormant and evergreen species are forced to dormancy due to low temperature, fertilizer should be stopped.
