Native to: As a cultivar, Hoya cv. 'Joy' does not occur naturally in the wild but has been developed through hybridisation​

Water: Requires well-draining soil; water thoroughly but allow the soil to dry out between waterings. Overwatering can lead to root rot, so it's essential to let the top layer of soil dry before the next watering. ​

Light: Thrives in bright, indirect light; avoid direct sunlight, which can scorch the leaves. Insufficient light may result in slower growth and reduced flowering.​

Humidity: Prefers moderate to high humidity levels. While it can adapt to average indoor humidity, increasing humidity through occasional misting or using a humidity tray can promote healthier growth.​

Temperature: Favours temperatures between 18–24°C. Protect from cold drafts and avoid exposure to temperatures below 15°C.
