The Cultivation Method of Dendrobium thyrsiflorum
Dendrobium thyrsiflorum, with its elegant orchid shape and medicinal value, has become a favorite among many gardening enthusiasts. This article will systematically explain the scientific care system for this orchid plant, from environmental regulation to pest and disease control, to help you easily create your own tropical garden.
Four Core Elements of Dendrobium thyrsiflorum Care
Precise Temperature Control
The native environment of Dendrobium thyrsiflorum is the tropical monsoon climate, it is recommended to maintain an ideal growth range of 15-28°C. Special attention should be paid to keeping warm in winter, and measures should be taken when the temperature drops below 8°C, such as using double-layer shading nets or moving indoors. In summer, activate the atomizing cooling system when the temperature exceeds 32°C.
Intelligent Light Adjustment
It is recommended to build a shading shed with 60% light blocking rate, and expose to 3 hours of soft morning light in spring and autumn. In summer, use double-layer shading nets to control the measured light intensity between 12000-15000Lux. In winter, it can be increased to 5 hours of scattered light.
Gradient Water Management
In the growing season (April-October), maintain a substrate humidity of 70%, and spray twice a day in the morning and evening. In the dormant season (November-March), adjust to watering the roots thoroughly once a week. Special attention should be paid to drainage during the rainy season, and it is recommended to use a mixed matrix of volcanic rock and pine bark (3:7).
Scientific Nutrient Ratio
Adopt the principle of "frequent application of thin fertilizer," and spray a 2000-fold solution of N-P-K=20-20-20 every week. Mix bone meal (5%) and decomposed sheep manure (10%) into the matrix as a base fertilizer. Apply additional phosphorus and potassium fertilizers during the budding stage, adjusting the ratio to 10-30-20.

Advanced Care Techniques
Dividing Propagation Operation
Select healthy mother plants that are over 3 years old and divide them before spring sprouting. Use a disinfected knife to divide, keeping 4-5 pseudobulbs per cluster. After applying charcoal powder to the wounds, wrap with moss and plant in a breathable pot.
Shaping Pruning Art
Perform shaping pruning every March, removing withered old stems and retaining the current year's sturdy branches. Guide the formation of a waterfall shape by tying, while keeping 1/3 of the new buds. After pruning, spray with a 800-fold solution of carbendazim to prevent infections.
Comprehensive Pest and Disease Control
Disease Identification and Treatment
Black spot disease initially presents as small brown spots and can be controlled with a 600-fold solution of 70% mancozeb. Sooty mold disease often occurs in environments with poor ventilation, in addition to treating with a 800-fold solution of 50% carbendazim, it is necessary to simultaneously improve air circulation.
