The Cultivation Method and Precautions for Tian Gong Dendrobium
As a star variety among orchid plants, Tian Gong Dendrobium is highly favored for its elegant flower posture and medicinal value. This epiphytic plant, native to tropical rainforests, can display vibrant vitality on balcony windowsills through scientific care. Mastering its growth habits can easily create a dedicated orchid rhyme space.
Control of Growth Environment for Tian Gong Dendrobium
Selection of Cultivation Substrate
Use porous plastic pots or unglazed ceramic pots, combined with pine bark, broken charcoal, and volcanic stones (proportion 4:3:3) to prepare the substrate, ensuring breathability while retaining moderate water retention. A 3cm thick layer of broken bricks should be placed at the bottom of the pot as a drainage layer.
Light and Temperature Control
In spring and autumn, full sun exposure should be combined with a 70% shade net, and in winter, move it to a sunny window sill to maintain 5 hours of direct light. In summer, use air conditioning or fans to maintain an environment below 28°C, and during the winter dormancy period, maintain an 8°C day-night temperature difference to stimulate bud differentiation.
Key Points of Daily Maintenance for Tian Gong Dendrobium
Water Management Techniques
Water once a week using the immersion method, and water when the surface of the substrate turns white. Combine morning and evening foliar sprays to maintain air humidity between 60%-75%. In the rainy season, set up a rain shelter to prevent waterlogging and root rot.
Nutrition Supply Plan
Apply orchid-specific fertilizer (N-P-K=20-20-20) every half month during the growing period, and switch to high-phosphorus and potassium fertilizer before flowering. Add decomposed sheep manure balls as a base fertilizer when repotting in spring, with a volume of 1/10 of the potting soil.
Common Problem Handling for Tian Gong Dendrobium
Disease Control Methods
For the early stage of black spot disease, spray the back of the leaves with garlic extract (1:20), and in severe cases, alternate the use of benz醚甲环唑 and mancozeb. For the prevention and control of (T-J) disease, promptly remove diseased leaves, maintain good ventilation, and spray pyraclostrobin before the plum rain season.
Physiological Yellow Leaf Treatment
Strong light damage manifests as leaf tip burn, and gradually increase shading. For iron deficiency chlorosis, apply EDTA chelated iron fertilizer, combined with ferrous sulfate 1000 times solution for root irrigation, twice a month until the new leaves turn green.
By systematically understanding the ecological needs of Tian Gong Dendrobium and combining regular observation with meticulous management, even a closed balcony can create a suitable growth microenvironment. It is recommended to establish a maintenance log to record temperature and humidity changes, combined with seasonal adjustments to maintenance strategies, to allow this "fairy in the air" to bloom beautifully year after year.
