How to Care for Hoya pandurata (Vietnam Form)
 
Light: Bright, indirect light is best. Tolerates morning sun but avoid intense midday exposure to prevent leaf damage.
 
Watering: Water when the top 2 – 3 cm of substrate is dry. Use breathable pots and allow excess water to drain freely.
 
Humidity: Prefers 60 – 70% humidity. Will adapt to lower levels, but higher humidity encourages larger leaves and more blooms.
 
Temperature: Maintain 18 – 26 °C. Keep away from cold windows or drafts below 12 °C.
 
Substrate: Use a loose, chunky mix of orchid bark, perlite, and coco coir for good aeration and drainage.
 
Fertilizing: Apply a balanced liquid fertilizer every 4 – 6 weeks. Indoor plants don’t require seasonal breaks in feeding.
 
Pruning: Trim long vines to shape or encourage branching. Never cut flower spurs (peduncles), as blooms return on the same structures.
 
Blooming Tip: Consistent light, stable humidity, and slightly rootbound conditions often trigger flowering.

Common Issues and Solutions
 
Yellowing Leaves: Usually due to overwatering or compacted soil. Check drainage and let roots breathe.
 
Root Rot: Avoid standing water and use airy substrate. Repot if roots turn dark or mushy.
 
Pests: Mealybugs and mites are rare but possible. Wipe leaves and use insecticidal soap at first sign.
 
Leaf Drop: Caused by sudden drafts or light changes. Keep conditions consistent.

Propagation Guide
 
Stem Cuttings: Take a cutting with at least two nodes and root in water or moist sphagnum moss. Use high humidity for best success.
 
Best Season: Spring and summer offer the fastest results for both rooting and new growth.
