Renanthera Orchids
Family
Epidendroideae
Origin
Southeast Asia
Description
The genus Renanthera is closely related to Arachnis and Vandopsis with its climbing growth habit in which roots grow along the stem. Some of the species producing the coolest inflorescences in the orchid world filled with small to medium sized flowers in red to orange. These orchids are extraordinary beautiful with long inflorescences of gorgeous flowers.The size of the plants varies from approximately 50cm (e.g. monachica) and up to 4 meters
Environment
Renanthera orchid culture is very much similar to the growing conditions for Vanda orchids. All Renanthera species require a lot of bright light to grow well and bloom regularly. If the orchids aren t provided with sufficient light, leaves tend to grow bigger and become darker. In this case, the plants may look absolutely healthy, however, not blooming at all.
Renanthera orchids do not need a dormancy period for stimulation of flowering, and most species require warm temperature conditions (65-800 F) all year round. Like most orchids, Renantheras require the difference of several degrees between night and day temperatures to promote blooming.
Potting & Media
Most Renanthera species have extremely long roots that are sensitive to rotting, and therefore grow best in open baskets without potting substrate. They can also be planted in pots with bark or other well-aerated potting mixture for orchids, but in this case, the plants should be repotted regularly, at least every 2 years, and watering should be moderate but regular throughout the whole year.
Fertilize
Any balanced orchid fertilizer (look at the numbers on the container, 20-20-20, etc.) can be used to fertilize your orchid. Weakly ( strength), weekly works well. Once a month use clear water to flush any accumulated salts from the potting mix.
