Care tips

Renanthera need a very bright place. In summer, please make sure te plants are protected against direct sunlight.

Temperature

During winter, the plants need a temperature of in between 16,5 and 22°C. In summer, the temperature can be in between 25 and 30°C. At night, it should drop a few degrees, so that the plants can cool down.

Humidity

We advise a humidity in between 45-75%. This varies per species within the gender.

Water

The Renanthera requires to be watered about once a week. In winter, this should be every 14 days. Sprinkle the roots at least once a week with air roots. The roots in the pot should never dry up completely.

Fertilizer

In summer, Renanthera can be fertilized lightly once a week. In winter, fertilizer is only necessary around once every two weeks.
The fertilizer is important, because there won’t be enough sunlight for the Renanthera. Normally, the sunlight provides the Renanthera with sugars that are essential to create the growth of flower branches. Therefore it’s harder for the Renanthera to start blooming without the fertilizer.

Repotting

In general, Renanthera can be repotted every 2/3 years. Repotting is also an option if the plant doesn’t grow well after a while (around 9 months to a year). The recommended mix for the soil is either rough bark (100%) or rough bark 85% combined with sphagnum (15%).
