What are the cultivation methods and precautions for Dendrobium orchids?

People usually have a better understanding of Dendrobium, and Dendrobium orchids are a type of Dendrobium, existing in the form of rare orchids and widely sought after by orchid lovers. Like other Dendrobium species, Dendrobium orchids grow in relatively dangerous and steep places, and harvesting them is not easy, which is why they seem so precious.

How to grow Dendrobium orchids

Dendrobium orchids are mainly distributed in tropical and subtropical regions of Asia. They prefer warm, humid and semi-shaded environments and are not cold-tolerant. The most suitable growing temperature is between 18 and 30°C. Dendrobium dislikes dryness and fears waterlogging, especially when new buds begin to sprout and new roots are forming, when sufficient water is needed. However, if it is too humid, such as when encountering low temperatures, it can easily rot. It relatively prefers light; sufficient sunlight in autumn leads to good flowering and a large number of blooms.

Cultivation methods and precautions for Dendrobium orchids

I. Cultivation methods

1. Soil

To grow Dendrobium orchids, use loose and breathable soil. Peat moss and charcoal can be mixed as its growing medium. At the same time, some tiles can be placed at the bottom of the pot, which will help its roots develop better.

2. Humidity

Dendrobium orchids relatively prefer humid environments. When it is especially hot, some water needs to be sprinkled around them. This way the air humidity will increase, but on rainy days be careful not to let water accumulate in the pot.

3. Temperature

It prefers warmth. Normally, the temperature should be kept at 15-28°C, and the temperature difference between day and night should be relatively large, because if the temperature difference is too small, its growth and flowering will be affected.

4. Light

It relatively prefers semi-shaded environments. In spring and summer, shade treatment should be provided, and quite a lot of shade is needed, about 60%-70%. But in winter, it still needs more light, so no shading may be needed; if shading is required, only 20%-30%.

5. Fertilizing

Fertilizing should begin in the second year, twice each year. The first time is in April, and pig hair, soybean dregs and the like can be used; after fermentation, apply them at the roots to help young buds grow better. The second time is in November, using the same fertilizing method.

II. Precautions

1. Watering. More water should be given in spring and summer, and watering should be reduced after September.

2. Pruning. Pay attention and observe regularly, and promptly cut off old branches, diseased and weak branches, and branches that are too dense.

3. Repotting. Repot it every two to three years to give it better growing conditions.
