Family Culture skills of Dendrobium

Dendrobium, along with Cartland, Phalaenopsis and Wandai Orchid, is one of the largest genera in Orchidaceae. There are 1500 to 1600 native species, of which about 60 species are native to China. According to its biological characteristics and ecological requirements, Dendrobium can be divided into two categories: deciduous Dendrobium and evergreen Dendrobium. The deciduous Dendrobium extracted inflorescence from the upper part of the pseudobulb every year, sprouted from the base after flowering, and grew into a new pseudobulb, and the leaves fell off at the end of the growing period or in the following spring. The leaves of evergreen Dendrobium can remain unwithered for several years, and the inflorescence is often drawn at the top or upper node of the pseudobulb.

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 flower shape, beautiful, gorgeous and colorful, many species smell fragrant, is an important cut flower species, can also be potted.

In order to raise Dendrobium well, we should do the following according to the biological characteristics of different kinds of Dendrobium.

Shading

Dendrobium is often attached to tree trunks or rocks in the tropical rain forest in its place of origin, so it likes the semi-shaded environment. During the peak growth period of spring and summer, it should be shaded by 60% to 70%, but it needs more sunlight during the winter dormant period. Generally, it can shade 20% to 30%, or no shade.

Heat preservation

Dendrobium likes high temperature and humidity. The overwintering temperature of deciduous species 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.

Proper watering

Dendrobium not only likes to have enough water, but also avoid being too wet, which will cause rotten roots and poor growth, or even death. Fallen leaves can be properly dried and watered less in winter, but potted materials should not be too dry and air humidity should not be too low. Evergreen species still need to maintain sufficient moisture as long as the greenhouse temperature is high in winter.

Frequent spray

In the sunny, dry and hot growing season, water should often be sprayed around the pot plants to improve air humidity. The humidity in the rainy season is relatively high, so you can stop spraying and pay attention to not accumulating water in the basin.

adequate manuring

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