Bottle Orchid Cultivation Management Methods and Daily Care Key Points
Soil selection: Bottle orchid has well-developed taproots and is not strict about soil requirements, but loose, fertile media is best. The general ratio of cultivation soil is 4 parts garden soil, 4 parts sandy loam, and 2 parts leaf mold. Add some bone meal and rapeseed cake fertilizer appropriately. It adapts widely to soil acidity and alkalinity; the ideal is neutral to slightly acidic with a pH between 6.5-7.0. After two or three years of cultivation, the pot soil should be changed; be sure not to damage the fibrous roots.
Timely fertilization: Bottle orchid likes fertilizer. After the beginning of spring, apply water-soluble fertilizer about once every 7 days, using light fertilizer frequently. The ratio is: 1 part fertilizer to 9-10 parts water. During the branch and leaf growth period, orchids need more nitrogen fertilizer; during the bud emergence period and fruit development period, they need more phosphorus and potassium fertilizer. Apply fertilizer three times a year. Base fertilizer should preferably be applied in mid-December in winter, accounting for 50% of the annual fertilization amount. Apply a top dressing once in July to promote flower bud differentiation and fruit enlargement. Apply a top dressing once in September to make the plant robust and the fruit plump and glossy. Do not fertilize in winter. This management can help ensure many flowers and fruit covering the branches.
Sufficient light: Bottle orchid likes light and needs sufficient light throughout its entire growth process. Insufficient light will cause excessive growth of branches and leaves, affect flower bud differentiation, and easily cause physiological fruit drop. For home-grown bottle orchids, daily sunlight exposure cannot be less than 6 hours. Bottle orchid is a warmth-loving plant, but it has strong cold resistance and is relatively easy to overwinter indoors in the south.
Artificial pollination: Most bottle orchids are dioecious (very few are monoecious), and parthenocarpic fruiting ability is weak. Bottle orchids should be paired with pollinator varieties, or male pollen should be collected for artificial supplementary pollination. Spraying 2.4-de-10ppm, or naphthaleneacetic acid 50ppm, or 920 200ppm during full bloom also has a certain effect on improving the parthenocarpic fruit-setting rate of bottle orchids. There are very few pests and diseases; the main control target should be scale insects.
