Growing Hoya Callistophylla
Choosing the Right Location

Soil Requirements
- Soil Type: Use a well-draining potting mix, preferably one formulated for succulents or aroids. You can also create your own mix using potting soil, perlite, and orchid bark.
Potting
- Container: Choose a pot with drainage holes to prevent waterlogging.
- Repotting: Hoya Callistophylla benefits from being repotted every 2 to 3 years or when it outgrows its container.

Caring for Hoya Callistophylla
Watering
- Watering Schedule: Water thoroughly but infrequently. Allow the top inch of soil to dry out between waterings. Overwatering can lead to root rot, which is the most common issue for Hoya plants.
- Humidity: Hoya Callistophylla enjoys higher humidity levels. You can increase humidity by misting the plant or placing it on a pebble tray filled with water.
Fertilizing
- Fertilizer Type: Use a balanced, diluted liquid fertilizer every 4 to 6 weeks during the growing season (spring and summer). Reduce feeding in fall and winter when the plant is dormant.
Pruning and Training
- Pruning: Prune to remove dead or yellowing leaves and to encourage bushier growth. You can also trim back long vines to maintain the desired shape.
- Training: Use a trellis or support for the plant to climb, as it naturally grows in a vining manner.
Propagation of Hoya Callistophylla
Methods of Propagation
- Stem Cuttings:
- Take a cutting with at least two leaves and a node.
- Allow the cutting to callous for a few hours before placing it in soil or water to root.
- Leaf Cuttings:
- Although less common, you can propagate using leaf cuttings. Ensure the leaf has a node for successful rooting.
Rooting Conditions
- Soil Method: Keep the soil moist but not soggy. Cover the pot with a plastic bag to maintain humidity.
- Water Method: Place the cutting in water, ensuring the node is submerged but leaves are above water. Change the water weekly.
