Hoya ranauensis is native to the region around Ranau in Sabah, Malaysia, on the island of Borneo. It thrives in tropical forests where it often grows as an epiphyte, clinging to trees and deriving moisture and nutrients from the air and surrounding debris.​

Native to: Ranau region, Sabah, Malaysia, Borneo.​

Water: Hoya ranauensis prefers its soil to dry out between waterings. Water the plant thoroughly, allowing excess water to drain away, and then wait until the top third of the potting medium feels dry before watering again. Overwatering can lead to root rot, so it's crucial to ensure the plant is not left in soggy conditions.​

Light: This Hoya species flourishes in bright, indirect light. While it can tolerate some direct morning sunlight, it's best to avoid harsh afternoon sun, which can scorch the leaves. Insufficient light may result in reduced growth and a lack of flowering.​

Humidity: Originating from a humid tropical environment, Hoya ranauensis appreciates higher humidity levels. Aim for humidity above 60%. If maintaining such levels is challenging, especially during winter months, consider using a humidity tray or placing a humidifier nearby. ​

Temperature: This plant prefers warm indoor temperatures, ideally between 18°C and 26°C. It does not tolerate cold drafts or temperatures below 10°C. Keeping it in a stable environment away from sudden temperature fluctuations will promote healthy growth.
