Cymbidium dayanum, the tree orchid, is a species of orchid that is widespread in Southeast Asia.
Day's cymbidium typically exhibits strong resistance to disease and encounters relatively few insect pests. Its care is considered difficult because it demands high humidity combined with good ventilation and a low presence of harmful pathogens. Too much watering can result in root rot. Although anyone can grow Day's cymbidium, keeping it healthy and getting it to bloom again requires more cultivation experience.
How to keep Cymbidium Dayanum.
Light
Day's cymbidium is native to habitats like forest understories or rocky areas, where it grows in natural shade. It prefers partial sun but can adjust to full sun or full shade, showing its versatile and hardy nature.
Water
Day's cymbidium thrives in high humidity and needs to be watered regularly, about once a week. It has low drought tolerance, so it is usually grown indoors. As an evergreen plant, Day's cymbidium grows consistently throughout the year. However, to keep its foliage vibrant and healthy, it requires adequate moisture.
Temperature
Day's cymbidium does well in warm settings. It prefers moderately high temperatures but not extreme heat and humidity. Sunlight warms the plant and encourages flowering. However, long periods of direct sun in summer can cause sunburn, so its exposure should be limited during that season. The plant typically tolerates cold poorly, so it needs adequate protection and warmer conditions in winter to prevent freezing.
Fertilizer
Proper fertilization is essential for Day's cymbidium's health and appearance. Fertilize Day's cymbidium in summer, repeating the application monthly throughout the season. Nutrients supply energy for growth and help maintain the plant's parts. Fertilization improves Day's cymbidium's flower display, ensuring the best blooms.
Pruning
The day’s cymbidium displays stunning blooms and lush foliage. To encourage future blossoms, prune the plant from early to late spring. During pruning, focus on removing spent flowers and yellowing leaves, but be careful to avoid cutting any new growth. This practice enhances air circulation and light penetration, reduces the risk of disease, and fosters vigorous growth and vibrant flowers.
Pot & Repot
When repotting Day's cymbidium, select a slightly larger pot with good drainage—ideally a clear orchid pot. Use an orchid-specific, well-draining medium containing bark or moss. Carefully clean the roots and remove any that are dead or rotting. Repot after the flowers have finished, typically in spring or fall; water thoroughly afterward and place the plant in bright, indirect light. Once repotted, avoid disturbing the roots.
