How to Grow Renanthera / One of the Floating Flower Garden

When indoors, place the renanthera in an airy location where the sun can shine on them behind a lace curtain. Keep it out of the direct path of air blown by an air conditioner or heater. When outdoors, keep the renanthera in a location out of direct sunlight between the spring and fall seasons, when outdoor temperatures are high. Once outdoor temperatures start falling under 15°C, bring them inside to a bright, warm indoor location early on. Ideally, the indoor temperature should be 15°C or higher. Keep the renanthera out of locations that do not fall under 15°C even at night. ★Tip Renanthera loves the sun. However, when they are exposed to direct sunlight for long periods of time, their leaves burn, change color, and become brittle.

Water the renanthera with tap water as though washing it, and place it in the glass while it is still wet. Ideally, you should water your renanthera twice a day, once in the morning and once in the evening, from spring up through fall, and once at night during winter. The state of dryness differs according to your orchid’s surroundings. Adjust the frequency of watering and the amount of water you use according to the situation. ★Tip When narrow wrinkles become visible on the leaves, it is a sign that they are dry. Sink the renanthera up to the tips of the leaves in the daytime and dry them off in an airy location at night. The appearance of new bright green roots at the end of the roots indicates that the renanthera is healthy. *Please do not put water in the glass.

Q: I want to grow renanthera indoors. However, there is nowhere inside where sunlight shines from behind lace curtains. What should I do? A: As it is better to keep renanthera out of strong sunlight, placing them by a window facing north is a good alternative. At the same time, renanthera cannot grow with too little sunlight. If you find it difficult to give them sufficient sunlight, one solution is to use a growth lamp. Q: The leaves of my renanthera have become wrinkled and yellow in color. What should I do? A: You may not be watering your renanthera with enough water. Submerge them in water up to the tip of the leaves during the day and dry them off in an airy location at night.
