When will Dendrobium candidum, "Chinese immortal grass", bloom? How many times a year do you bloom? How can it blossom?

Dendrobium candidum, also known as Dendrobium, Black Section Grass, Yunnan Iron, Iron Dou, is a common valuable traditional Chinese medicine in daily life, with laudatory names such as "life-saving fairy grass", "gold in medicine", "Chinese fairy grass" and so on, so it is planted in many places. when will Dendrobium bloom? How many times a year do you bloom? How can it blossom?

Dendrobium candidum blossoms once a year, and blossoms from April to June every year. The petals are yellowish green and the florescence is from March to June. Racemes often emanate from the upper part of a leafless old stem with 2 × 3 flowers; inflorescence stalks 5 × 10 mm long, with 2 × 3 short sheaths at base; inflorescence rachis repand-curved, 2-4 cm long; floral bracts scarious, pale white, ovate, 5 × 7 mm long, apex slightly obtuse; pedicels and ovary 2 × 2.5 cm long. The plant blossoms, generally does not sprout new leaves after falling leaves, but sprouts new branches in the root of the stem in the following spring, while the old stem gradually shrinks and no longer blossoms.

As the flowering time of Dendrobium candidum is very short, so the timing of picking is very important, must be picked in time, early lack of drug power, too late easy to rot. It can be said that Dendrobium candidum flower is also the most precious part of Dendrobium candidum, and its price is higher than that of Fengdou. It is understood that the iron maple bucket on the market is about 30 yuan per gram, while Dendrobium candidum flowers are sold for 20.8 yuan per bag of 0.5 grams. Compared with Dendrobium candidum, its flowers are more suitable for daily tea health care.

How do you plant it?

1. For the seed material of potted Dendrobium candidum, 1/3 of the pot bottom should be covered with stones with a particle size of 2-3 cm, and the upper 2/3 should be covered with fine crushed bark and grained stones.

2. The best season for pot transplanting and propagation of Dendrobium candidum is from the Spring Equinox to Qingming Festival, which is also the sprouting season. Pay attention to the depth, too deep to bury the germination point under the plant material, it will affect the germination rate, too shallow root is difficult to moisturize, affect growth, we should pay attention to the season and cultivation techniques.

3. Maintenance and management: in the pot planting method of Dendrobium candidum, various environments and methods of domestic Dendrobium are different. Planted on the balcony or window frame where Rain Water cannot be drenched directly, during this period of spring, because Dendrobium herbs love the sun, it is suitable for direct sunshine; open-air balcony planting should pay attention to heavy rain or too much rainfall, easy to rot roots and seedlings, the upper shed cover for prevention. According to the actual situation, watering is generally 5-7 days, but not too wet or too dry.

4, summer and autumn season: the balcony or window frame without Rain Water is sprayed at 6 am every day, and the open-air balcony is covered with a shade shed to prevent Rain Water or strong sunlight.

5. Spray water once every 7-10 days on the balcony or window frame in winter, suitable for direct sunlight, do not spray water below 5 ℃, fertilize, smash longan shell and litchi shell and put them on the basin surface. Watch out for snails.

Harvest: sprout harvest at the end of spring every year, cut off more than three-year-old stems and branches, leaving buds, so that they can continue to grow.

Note:

In the summer and autumn high temperature season, the moisture content in the substrate should be controlled as much as 40% to 50%. In the winter after November, the temperature gradually decreases, and Dendrobium candidum basically stops growing and enters a dormant state when the temperature is below 10 ℃. At this time, the requirement for moisture is very low, and the water content of the substrate should be controlled within 30%.

Among the pot planting methods of Dendrobium candidum, it is better to plant Dendrobium candidum in spring (March-April) and autumn (August-September), especially in spring than in autumn. This is mainly to make full use of the spring March, the climate rebounded, the wind and the sun are warm, the spring rain such as oil, the golden season of recovery of all things, suitable temperature and humidity, sunshine, Rain Water and other conditions are conducive to stimulating the rapid germination of axillary buds at the base of the stem of Dendrobium. At the same time, it grows aerial roots for young buds to absorb nutrients and water, so as to achieve the growth purpose of first roots and then buds. After the preparatory work before planting is done, we can choose the best planting season to vigorously develop the production of Dendrobium.
