How to grow Dendrobium officinale

1. Maintenance methods

1. Temperature: Dendrobium primula likes warmth, and the temperature between 15 and 28 degrees is more suitable, which can be seen from its distribution range. In addition, it is not very cold-resistant, so the potted plants can be kept indoors all the time.

2. Light: When Dendrobium officinale is first planted, it does not require much sunlight and can be placed in a semi-shaded place with a little scattered light. It can then be adjusted according to the season. In spring and autumn, good light can be provided. If the light at noon is too strong, light can be provided in the morning and evening. In summer, it needs to be placed in a cool place.

3. Watering: In the early stage of planting, not much water is needed, so spraying can be used. After that, the amount of watering needs to be adjusted according to the dryness and wetness of the substrate. Generally speaking, a semi-dry and semi-wet state is better. In very hot weather, water once a day. It will go dormant in winter, so you can reduce the amount of watering.

4. Fertilization: Generally speaking, potassium fertilizer is the most important fertilizer for it. After germination, fertilize once a week.

2. Breeding techniques

1. Repotting: Repotting needs to be done regularly, but not too frequently. Generally speaking, once a year or once every two years is more appropriate. It is more appropriate to repot before germination in spring. Don't repot when the temperature is too low, otherwise its roots will be frozen. The new soil used for repotting can be prepared with coconut coir, dead branches, peat soil and other materials, which can effectively ensure the development of the root system.

2. Pruning: This step is also very important in the maintenance of Dendrobium officinale. The first thing is to trim its branches and leaves, and regularly cut off the old and dry ones. Another thing is its shape, because it can be appreciated and its shape can be adjusted.

3. Problem diagnosis and treatment

1. Diseases: The most important one is called "soy pollutant disease", which occurs more frequently from March to May. The infected leaves need to be removed in time and then sprayed with medicine.

2. Pests: The main one is called "snail", which will eat leaves and flowers. You can spray pesticides in time.

IV. Other issues

1. Toxicity: Dendrobium officinale is not poisonous, so there is no need to worry about its harm.

2. Can it be kept at home: Yes. It is quite ornamental because its flowers have a peculiar shape and are a good place to place potted plants at home.
