Ideal Growing Conditions for Hoya Rangsan
Sunlight
Hoya Rangsan prefers bright but indirect sunlight. Avoid placing it in direct sunlight to prevent leaf burn. Instead, give it 2-3 hours of mild morning sunlight for better foliage color and increased flower production.
Soil
For robust growth of Hoya Rangsan use a well-draining potting mix as the base. Add perlite or pumice, orchid bark, coarse sand, and compost to improve drainage and nutrient availability. The ideal soil pH is slightly acidic to neutral, between 6.0 and 7.0.
Water
Water the plant once a week in spring and summer. Hoyas prefer well-draining soil, so it’s important to allow the topsoil to dry slightly between watering. But don’t let the soil dry out completely.
Temperature & Humidity
Hoyas thrive in temperatures ranging from 60°F to 85°F (16°C to 29°C). To maintain their vibrant foliage color and promote healthy growth, avoid subjecting them to higher temperatures. Additionally, ensure the flowers are shielded from drastic temperature changes to prolong their blooming period.
High humidity levels of about 40-60% are essential for the plant’s well-being. Combat dry days using a humidifier or placing a pebble tray nearby to help maintain the required humidity levels.

Fertilizer
Hoya Rangsan does not require frequent feeding but appreciates a monthly dose of diluted liquid fertilizer (at half strength) during spring and summer. However, you should reduce the plant’s feeding in the colder months.
To boost flower production, use a high-phosphate plant food before the blooming season. This will help promote abundant and beautiful blooms.
Repotting
Hoya Rangsan requires repotting every 1-2 years to maintain its health and growth. Use a slightly larger pot with well-draining soil to accommodate its expanding roots. Spring is the best time for repotting when the plant is actively growing. Avoid excessive disturbance to the roots during the process.
Pests & Diseases
Hoya plants are prone to sap-sucking pests like aphids, mealybugs, and spider mites. Combat these pests by using a neem oil solution as a natural insecticide. Additionally, ensure the plant’s health by avoiding overwatering, which can lead to fungal diseases.
