How to Grow Dendrobium Flowers? A Detailed Guide to Care Methods and Tips

Dendrobium is not only a traditional and precious Chinese medicinal herb, but also an excellent health tonic ingredient, and Dendrobium also blooms, giving it considerable ornamental value. Dendrobium flowers are very similar in shape to orchids, with a captivating fragrance, very beautiful and elegant. So how do you grow Dendrobium flowers?

How to Grow Dendrobium Flowers

1. Light: The native environment of Dendrobium officinale is generally under tree shade and in shaded spots. The growing environment requires moderate shading.

2. Temperature: Dendrobium officinale stops growing and begins dormancy below 5°C. When temperatures are too low, watch out for cold damage, and it is best to keep them above 0°C. When temperatures are too high, around 35°C, growth also stops. The most suitable growing temperature is around 25°C~30°C.

3. Substrate: For planting Dendrobium officinale, it is best to use a substrate with good air permeability and good drainage as the growing material. A mix of orchid stone + granular peat + bark is generally recommended. However, due to large-scale production, the cost is relatively high, so a single bark substrate can also be used.

4. Humidity: Equip a hygrometer, and it is best to keep humidity above 60%. During rainy weather, when humidity is above 90%, ventilation should be strengthened to prevent bacteria from developing.

5. Watering method and water quality: When watering, spray frequently and drench thoroughly less often. Generally, wait until the substrate is dry before drenching thoroughly.

6. Ventilation: "Orchids value ventilation": Air circulation is very important for Dendrobium officinale and can also reduce the occurrence of diseases. Air circulation is equally important for the roots within the substrate, so we recommend using granular materials, and watering must be thorough to bring fresh air into the substrate.

7. Fertilization method: Use compound fertilizer containing trace elements. Apply light fertilizer frequently, and never use heavy fertilizer, otherwise it will cause fertilizer damage. When new shoots sprout each spring, slow-release fertilizer can also be applied as a base fertilizer.

Later-Stage Management

1. Watering: In the later stage after planting Dendrobium, if air humidity is too low, water frequently to maintain moisture. A sprayer can be used to water in the form of a mist.

2. Topdressing: Dendrobium grows in poor soil, so attention should be paid to topdressing. The first time is around Qingming, mainly with nitrogen fertilizer mixed with pig and cattle manure and river mud. The second time is around Lidong, using peanut cake, rapeseed cake, superphosphate, etc., mixed evenly with river mud and pasted onto the roots. In addition, foliar topdressing can also be used.

3. Adjusting canopy density: The canopy density of Dendrobium growing sites is about 60%, so the host trees should be pruned and trimmed regularly to avoid excessive shading or insufficient canopy density.

4. Pruning: Before new growth each spring, while harvesting old stems, cut out dead stems within the clump, and remove diseased stems, weak stems, and diseased roots. After 6~8 years of planting, depending on the growth of the clump base, turn over the clump and divide it again for propagation.

Morphological Characteristics

Authentic Dendrobium officinale is a herbaceous plant with clustered, cylindrical stems, 10~30 cm tall and 3~8 mm thick. After drying, they are grayish-green. The leaves are papery, oblong-lanceolate. Where the leaf tip extends downward, it leaves a ring-like gap, forming a "black node". It has a slight grassy fragrance, tastes bland when chewed, with an initial slippery feeling, and after a long time a strong sticky, clinging feeling.

According to ancient records, authentic old Yanshan Dendrobium officinale is produced in Yandang Mountain, Zhejiang Province. The old Yanshan Dendrobium officinale of Zhejiang Province is full of gelatinous substance, leaves no residue after long chewing, has plump, solid stems, and the best efficacy.

Natural propagation is very difficult. In addition, Dendrobium grows and develops slowly, has small leaf area and low photosynthetic intensity, and has very strict requirements for warm, humid climate conditions. Therefore, wild Dendrobium is on the verge of extinction. Compared with Dendrobium, Dendrobium nobile flowers are even more precious. About 100 grams of Dendrobium are needed to harvest 1 gram of Dendrobium nobile flowers, which can truly be called one in a hundred.

Rare things are precious. Not to mention the low yield of Dendrobium officinale flowers, the requirements for cultivation and picking are also very high. And compared with Dendrobium, preserving Dendrobium flowers is even more difficult. First, the flowering period of Dendrobium officinale is short, so it must be picked at the right time. If picked too early, the medicinal potency will be insufficient, while if picked too late, the Dendrobium flowers may rot. Therefore, the season each year when Dendrobium officinale flowers can truly be harvested is only a short one or two months.
