Cultivation methods and precautions of Dendrobium officinale

1. Maintenance methods

1. Temperature: Dendrobium sphenanthera is suitable for growing in warm places, specifically between 15 and 28 degrees. In a too hot environment, it will have an adverse effect on its growth. Therefore, it needs to be adjusted in summer. In addition, the temperature should not be too low in winter, so it is more appropriate to place potted plants indoors.

2. Light: Dendrobium sphenanthera prefers a semi-shady or semi-sunny environment. In other words, it should not be too dark, nor should it be exposed to direct sunlight. Therefore, it can be adjusted according to the season and the intensity of light. It can be exposed to mild light, but needs to be shielded from strong light.

3. Watering: Dendrobium sphenanthera likes moisture. Its distribution area is mainly where the annual rainfall is above one thousand millimeters. If you raise it yourself, you need to replenish water in time. In addition, the air humidity should be above 60 percent. Therefore, pay attention to humidification when it is dry.

4. Fertilization: Dendrobium plants have aerial roots, so it is best to use foliar fertilizer to supplement fertilizer. Generally speaking, it is used during the growth period, once a week to ten days.

2. Breeding techniques

1. Reproduction: It can be propagated by cuttings. It can be done together with repotting. The materials chosen are mainly slender stems with many nodes. Then, it is time to choose a substrate with better air permeability. You can treat the wound with wood ash before inserting it. After insertion, place in a moist, cool place. Do not water for a week.

2. Pruning: For Dendrobium sinensis, its density should be kept at around 60%. Therefore, if the branches are dense, they need to be pruned in time. In addition, diseased and dry branches must be pruned off in time.

3. Problem diagnosis and treatment

1. Disease: "Black spot" is more common, which will cause many black spots to appear on the leaves and can be treated with Bordeaux. Then there is "soot mold disease," which causes a layer of black substance to appear on the leaves. It can be treated by spraying carbendazim in time.

2. Pests: There are "non-shield scale insects" and "snails", etc. If the number is small, they can be captured manually.
