Scientific Dendrobium officinale cultivation techniques: improving planting quality

Dendrobium officinale is quite particular when it comes to cultivation, and the Dendrobium officinale that many people grow may not be of high quality. So what are the Dendrobium officinale cultivation techniques? How can the cultivation quality of Dendrobium officinale be made higher?

1. Site selection for planting

Dendrobium officinale has some requirements for the environment that differ from those of other plants, and the planting requirements are for a somewhat shady and damp place. It is best to choose a slope that does not face the sun and has a relatively gentle gradient. It is even better if there are more rocks, but the rocks must not be too large. If there are weeds that are too dense, they need to be dealt with in a concentrated way. Before planting Dendrobium officinale, it is best to spread a layer of plant ash.

2. Planting methods

Dendrobium officinale is generally planted by division propagation. Choose a disease-free, robust mother plant of Dendrobium officinale and cut from it rhizomes about two years old. Then prune away some of the older branches on it, leaving new roots 2 to 3 cm long. When planting, it is best to plant it close against rocks or large trees.

3. Daily management

1. Temperature: the most suitable growing temperature for Dendrobium officinale is 20 to 32 degrees. In a high-temperature environment, good ventilation should be maintained, and in a low-temperature environment, work to raise the temperature should be done well.

2. Light: Dendrobium officinale needs an appropriate amount of supplemental light, but it cannot receive direct strong light, otherwise it will be sunburned. It is best to use scattered light or place it in the sun in the morning and evening to promote growth and keep the leaves green.

3. Watering: Dendrobium officinale needs to be watered once every two to three days to keep the soil moist and the surrounding air humid.

4. Fertilizing: Dendrobium officinale does not usually need much fertilizer. Generally, a slow-release fertilizer is applied once in early spring or at the beginning of winter, usually controlled at 10 to 15 fertilizer granules, and additional fertilizer can be applied appropriately according to the actual situation.

5. Other: Dendrobium officinale often develops some rotting branches and leaves, which should be cleaned up in time. The surrounding weeds should also be taken seriously and cleared away so as not to affect growth.

4. Pest and disease control

The growing environment of Dendrobium officinale is relatively humid, so it is very easy for bacteria to breed and for pests and diseases to be attracted. Therefore, pest and disease control is relatively important. Common diseases include soft rot, black spot and anthracnose; common pests include snails, Fiorinia scale insects and red spider mites. If these pests and diseases appear, the appropriate remedy should be applied in time and pesticide should be sprayed.

In fact, there are quite a lot of things to pay attention to in the cultivation of Dendrobium officinale, so planting requires even greater care. If the above matters are not paid attention to, the quality of cultivation is very likely to be affected.
