Dendrobium umbonatum Seidenf. 1985 orchid is a species of the Dendrobium genus. It is native to Thailand and Vietnam. This species was first described by Seidenf in 1985.

GROW AND CARE DENDROBIUM UMBONATUM ORCHID
1. Temperature of grow and care Dendrobium umbonatum orchid:
The Dendrobium umbonatum Seidenf. 1985 orchid that can live in both cold and hot areas. In cooler areas, the plants grow and flower more. The ideal temperature of these species is 20 ° C.
2. Humidity of grow and care Dendrobium umbonatum orchid:
Dendrobium umbonatum as well as most other orchids grow well in humid and airy conditions, relative humidity is 70%. If the cultivate are too moist and watery, which is a disadvantage for the growth of the Dendrobium umbonatum because of the possible root rot and the appearance of the seedling that grows from the top of the stem.
3. Light of grow and care Dendrobium umbonatum orchid:
Dendrobium umbonatum is a light-tolerant variety, which can be grown in direct light or diffused light for the Dendrobium umbonatum variety is 70%. So the cover with the shade of 30% underground and 40% on top, with light intensity from 15,000-30,000 lux is very suitable for the development of Dendrobium umbonatum.
Dendrobium umbonatum can be planted under direct sunlight to grow well. However, in order to prevent the leaves from being burned, we have to practice the plants slowly. For Dendrobium umbonatum, it is better to remember that it is better for plants that have burns because excess light than lack of light. Lack of light for these species will cause significant degradation, the number of flowers is also very low, the plant is weak. In contrast, excess light just make the plants worse because the leaves are too yellow or lose all leaves, but the plants will adapt gradually and still ensure the flowering and beautiful flowers. However, ideal light conditions still produce the best results.
4. Watering for Dendrobium umbonatum orchid:
Dendrobium umbonatum is grown in more light conditions: 70% of light is about 20,000-30,000 lux, so Dendrobium umbonatum will be watered more than Cattleya: 2 times / day from May to November, 3 times / day from December to February and once per day from early March to late April. Watering once a day during the rest season will make the pseudobulb of Dendrobium umbonatum shed and wrinkled, but what is sure to happen when the rainy season comes, the shoots will grow very fast and very strong. Flowers will bloom for 3 months after rain, and may last up to December.
5. Fertilizer for Dendrobium umbonatum orchid:
Keep in mind that Dendrobium umbonatum has a straight upright stem which is highly nutritious, so they need lots of fertilizer and can use a variety of fertilizers.
Inorganic fertilizers used, usually 30-10-10, 3 times a week with 1 teaspoon / 4 liters. During the growing season (from the beginning of May to the end of January), one month before the rest season (during the month of February), we apply 10-20-30 fertilizer twice a week to create a tolerance for the plant before the rest season. In the growing season if the plants have flower buds, we substitute 30-10-10 by 10-20-20 fertilizer with the above fertilizer cycle until the flowers withered. During the rest season there is absolutely no fertilizer for Dendrobium umbonatum, or rather it reduces and does not fertilize Dendrobium umbonatum as it completes its annual growth. Dendrobium umbonatum usually completes the growth period in September to October when its last leaves are seen at the top of pseudobulb and stem. When the growth is complete, you reduce irrigation water and fertilizer slowly until nothing else for a period of about 4 weeks, at which time the plant needs as much sunshine as possible.
6. Rest season for Dendrobium umbonatum orchid:
Compared to Cattleya, the rest season of Dendrobium umbonatum is much more needed. Dendrobium's breaks time determines the quality of flowers when the rainy season comes. Depending on the locale, the choice of Dendrobium umbonatum breaks is different.
7. Repot Dendrobium umbonatum orchid:
Dendrobium umbonatum is a very sensitive orchid when its cultivate is unsuitable for its development and it appears that some seedlings grow on the top of the pseudobulbs. When this happens, you must repot, because the cultivate in the pot is damaged. This phenomenon is due to the fact that the cultivate is too moist like coconut fiber. Therefore, the roots in hydrothermal conditions will be completely rotten. By instinct to survive, orchids will respond by growing some young seedlings on top to maintain the race.
Observing the occurrence of seedlings growing on top shoots will also help the gardener to check that the planting method. Especially in terms of watering and fertilizing. In addition, once every two years, we need repot, because during growth period, moss growing in the pot, cultivate is damaged, the plant imbalance.
Repotting is similar to that of Cattleya. Dendrobium and Cattleya are very similar in breeding, meaning they also cut three pieces and sequences as well as Cattleya, but Dendrobium's rest season is two months. So we have to cut Dendrobium into 3 pieces before Cattleya 1 month.
All of the above factors are essential for orchids in general. To make the plant more beautiful, more durable, we have to study to make the climate, water, humidity, light, wind, fertilizer... like the original environment of each plants.
