Big惠兰 orchids belong to the Orchidaceae family, subsection Microsorum, and are native to India, Myanmar, Thailand, and southern China. Big惠兰 orchids are horticultural varieties, bred from multiple generations of crosses between large-flowered orchid species such as Dendrobium moniliforme, Cattleya, Cymbidium, Cypripedium, and Brassavola, resulting in a variety of colors encompassing almost the entire spectrum. Next, let's introduce how to cultivate Big惠兰 orchids.
1. Temperature
Big惠兰 orchids do not have high temperature requirements and can even grow in environments above 35 degrees Celsius. During the bud stage, it is important to place them in a warm area to grow, with the temperature not exceeding 5 degrees.
2. Watering
Watering is one of the most important aspects of cultivating Big惠兰 orchids. Use slightly acidic water for watering, preferably well water or spring water. If tap water is used, it should be left to stand for 2 days to allow chlorine to evaporate. During the summer, water every 2-3 days and frequently mist the area around the plant to maintain an 80%-90% humidity level.
3. Light
In the summer and autumn seasons, provide shade to prevent direct sunlight and exposure. In other seasons, they can be exposed to full-day sunlight.
4. Soil
Since the roots of Big惠兰 orchids are fleshy and have weak penetration, it is necessary to use a loose and well-draining substrate. A mixture of aquatic plants, tree bark, and coconut shell can be used as a substrate.
5. Fertilizing
In spring and autumn, when the plant is in the growing stage, apply a dilute fertilizer every 10 days. During the spring and summer, nitrogen fertilizer can be used, and before the autumn flowering period, the content of phosphorus and potassium fertilizers can be increased. For seedlings and during dormancy, foliar spray fertilization can be used.
6. Repotting
When the plant becomes too large, it is necessary to repot and divide the plant. After removing the plant from the pot, cut off the rotting roots, place a layer of broken tiles at the bottom of the new pot to increase drainage and aeration, then put the plant in the pot, fill it with soil and compact it, and then water thoroughly.
7. Diseases and Pests
The main diseases of Big惠兰 orchids include leaf blight, anthracnose, soft rot, and leaf spot, while the main pests include aphids, red spiders, and scale insects. Diseases can be controlled with chemicals like captan or carbendazim, and pests can be sprayed with fenvalerate, omethoate emulsion, dicofol, or dichlorvos. Spray twice a month.
