How to cultivate Dendrobium officinale

1. Maintenance methods

1. Temperature: Dendrobium plants generally like warmth, and the same is true for Dendrobium sphericalensis. Specifically, the more suitable range is fifteen to twenty-eight degrees. In addition, its cold resistance is not strong, so it needs to be protected from the cold in winter and try to keep the temperature between eight and ten degrees, but of course it does not need to be too high.

2. Light: Dendrobium sphaerocephalum is a shade-loving plant and is very afraid of strong light. When the light is not so strong, a little diffuse light needs to be provided. But in the summer when the light is very strong, and at noon in other seasons, it is best to move it to a cool place.

3. Watering: When Dendrobium sphaerocephalum is growing fast, it requires relatively more water. In addition, during droughts, water demand is relatively high. During the hottest times, daily is best. In winter, it may go dormant, so don't water it too much.

4. Fertilization: Since Dendrobium sphaerocephalum has aerial roots, foliar fertilizer is relatively suitable. It is more appropriate to spray once a week or ten days. In addition, basal fertilizer must be mixed into the substrate.

2. Breeding techniques

1. Reproduction: You can use the method of division. Spring is more suitable. The plants that are large in size and grow densely are selected as mother plants. After removing it from the pot, trim its root system, and then you can divide it into several parts from this point. Try to minimize damage to healthy roots. After dividing, you can plant them separately.

2. Pruning: For Dendrobium plants, the best shading degree is about 60%. Therefore, it needs to be pruned frequently. Generally speaking, concentrated pruning can be done once before spring germination. Generally speaking, just cut off the dry and sick ones.

3. Problem diagnosis and treatment

1. Disease: "Black spot disease" often threatens the health of leaves, which can be controlled by Bordeaux. There is also "soot pollution disease", which is common in spring and can be controlled with carbendazim.

2. Pests: There are many types, such as "non-shield scale insects", "snails" and so on. It can be controlled with dichlorodiphenyltrichloroethane, and the soil needs to be disinfected with quicklime and other substances.
