A suitable potting medium for this orchid would be a mixture of sphagnum moss, perlite, and peat moss. The ideal pH range of the soil should be between 5.5 to 6.5. It is recommended to use a shallow pot for this orchid as it has a shallow root system.
It thrives well in a warm, humid environment with bright but indirect light. A temperature range of 60-85°F (16-29°C) is ideal for its growth.
Watering Needs
As a terrestrial orchid, Roeperocharis wentzeliana requires consistently moist soil. It is essential to water the orchid regularly. Ensure not to allow the soil to dry out between watering, but also do not let it become waterlogged as it can lead to root rot. It is recommended to use distilled or rainwater for this orchid, as it is sensitive to chemicals in tap water.
Fertilization
Fertilize the orchid once every two weeks during the growing season with a balanced fertilizer. Dilute the fertilizer to half strength and apply it to the orchid's soil. Avoid fertilizing during the dormant winter months.

Propagation Methods for Roeperocharis wentzeliana Kraenzl.
Roeperocharis wentzeliana Kraenzl. can be propagated by a variety of methods including division, seed, and stem cuttings.
Division
The easiest method of propagating Roeperocharis wentzeliana Kraenzl. is by division. This should be done in the spring when the plant is actively growing. Carefully remove the plant from its container or dig it up from the ground. Use a sharp pair of scissors or a knife to separate the roots into smaller plants. Each division should have a healthy root system and several stems. Replant the divisions in fresh soil and water thoroughly.
Seed
Propagation of Roeperocharis wentzeliana Kraenzl. can also be done using seeds. However, this can be a bit more challenging and time-consuming. The plant produces small seeds that must be sown in a well-draining soil mix. Keep the soil moist and place the container in a warm, bright location. Germination can take several weeks to several months. Once seedlings have emerged, they should be transplanted into individual containers or into the garden.
Stem Cuttings
Propagation can also be achieved using stem cuttings. Take a stem from the plant and make a clean cut just below a node. Remove the lower leaves and plant the cutting in a well-draining soil mix. Keep the soil moist but not overly wet. Place the container in a warm, bright location. The cutting should take root within several weeks, at which point it can be transplanted into a larger container or into the garden.
