A detailed explanation of the propagation methods and management key points for the bottle orchid

It likes sunlight, tolerates slight shade, and prefers warm and humid zones.

Regulating water: During the branch and leaf growth period of the bottle orchid, excessive watering easily causes excessive vegetative growth of branches and leaves and hinders flower bud differentiation; too much water during the flowering period obstructs pollination and fertilization and easily causes flower and fruit drop; too much water during the young fruit development period easily causes physiological fruit drop; drought during the fruit growth period causes the fruit to wither and drop. Throughout the entire growth stage, the bottle orchid should keep the soil appropriately moist.

Choosing soil: The bottle orchid has well-developed taproots and is not strict about soil, but loose, fertile media are preferable. The general ratio of growing soil is 4 parts garden soil, 4 parts sandy loam, and 2 parts leaf mold. Add an appropriate amount of bone meal and rapeseed cake fertilizer. It adapts widely to soil alkalinity and acidity, with the ideal being neutral to slightly acidic, with a pH between 6.5-7.0; after two or three years of cultivation, the potting soil should be changed, and be sure not to damage the fibrous roots.

Timely fertilization: The bottle orchid likes fertilizer. After the beginning of spring, apply water-soluble fertilizer about once every 7 days, applying thin fertilizer frequently. The ratio is: 1 part fertilizer to 9-10 parts water. During the branch and leaf growth period, the orchid needs more nitrogen fertilizer, and during the budding period and fruit development period it needs 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 ensure many flowers and fruit covering the branches.

Sufficient light: The bottle orchid likes light and needs sufficient light throughout its entire growth process. Insufficient light causes excessive vegetative growth of branches and leaves, affects flower bud differentiation, and easily causes physiological fruit drop. For home-grown bottle orchids, daily sunlight exposure must not be less than 6 hours. The bottle orchid is a warm-loving plant, but it is relatively cold-tolerant and overwinters relatively easily indoors in the south.

Artificial pollination: Most bottle orchids are dioecious (very few are monoecious), and parthenocarpic fruit set is weak. Pollination varieties should be arranged for the bottle orchid, or male pollen should be collected for artificial supplementary pollination. Spraying 2.4-de-10ppm, or 50ppm naphthaleneacetic acid, or 200ppm gibberellin 920 during full bloom also has a certain effect on increasing the parthenocarpic fruit set rate of the bottle orchid.

There are very few pests and diseases; the main thing to control is the harm of scale insects.
