Hoya pubicalyx 'Silver Splash' – Growing and Care Tips


To help your Hoya pubicalyx 'Silver Splash' thrive, replicate its tropical habitat by providing adequate light, humidity, and a well-draining substrate. Follow these essential care tips:



 
Light: Provide bright, indirect light. Too much direct sunlight can scorch the leaves, while insufficient light will dull variegation.


 
Watering: Let the top 2 – 3 cm of soil dry out before watering. Use your finger to check the moisture level to prevent overwatering, which can lead to root rot. Ensure good drainage to avoid waterlogging.


 
Humidity: Prefers moderate to high humidity (50%+). Use a humidifier or humidity tray for optimal growth. Avoid misting the leaves directly to prevent fungal issues.


 
Temperature: Best grown in temperatures between 18 – 26°C. Keep away from cold drafts, which can harm the plant.


 
Fertilization: Feed monthly during the growing season with a balanced water-soluble fertilizer at half strength. A phosphorus-rich fertilizer will encourage blooming.


 
Potting Mix: Use a well-draining mix with orchid bark, perlite, and some potting soil to maintain healthy roots. Repot every 2-3 years to refresh the soil and provide room for growth.




Common Problems and Solutions



 
Yellowing Leaves: Caused by overwatering. Adjust watering schedules and ensure proper drainage. Check soil moisture regularly to prevent root rot.


 
Root Rot: Caused by soggy soil. Repot in fresh, well-draining mix, and remove affected roots to prevent further damage.


 
Pests: Mealybugs, spider mites, and aphids are common pests. Inspect the undersides of leaves regularly and treat infestations with neem oil, insecticidal soap, or use beneficial insects like ladybugs.


 
Browning Leaf Tips: Caused by low humidity or excessive sunlight. Increase humidity with a humidifier or humidity tray, and ensure the plant isn’t exposed to direct sunlight for prolonged periods.




Additional Growing Tips



 
Training: Encourage vines to climb a moss pole or trellis. Alternatively, let it cascade freely in a hanging pot for a stunning display.


 
Propagation: Propagate stem cuttings in water or moist potting mix. Ensure the cutting includes at least one node for successful rooting. Once roots develop, transplant the cutting into fresh soil.


 
Cleaning: Wipe leaves with a soft, damp cloth to remove dust and keep the leaves clean, allowing them to shine with their natural speckled appearance.
