Light

This plant favors bright, indirect light for upto 6-8 hours daily. In the absence of sufficient light, hoya becomes leggy. Also, avoid keeping the plant in direct sunlight.

If your home doesn’t have access to indirect sunlight, get help from artificial lights.

Soil

Use nutrient-rich cacti or succulent mix for growing hoya. However, you can add pumice, perlite, and ceramic balls to improve drainage.

Water

Water Hoya Callistophylla: when the top 1-2 inches of soil become dry, you can check the moisture in the soil by inserting your index finger in the soil. Remember that in winter, this plant turns dormant and does not require frequent watering.

Always water the plant thoroughly until it starts to come out from the drainage holes. Water the plant according to the climate almost once a week or when the soil is dry to the touch.

Temperature and Humidity

This tropical plant appreciates humidity and warmth. The ideal temperature range has to be 60-85 F, with the humidity levels up to 40-60 percent. To raise the humidity around the plant, mist it regularly.
