Hoya pubicalyx 'Silver Splash' – Growing and Care Tips


To help your Hoya pubicalyx 'Silver Splash' flourish, replicate its natural tropical setting by providing adequate light, humidity, and a well-draining substrate. Below are essential care guidelines:



 
Light: Provide bright, indirect light; avoid intense direct sun that may burn leaves, and insufficient light that dulls variegation.


 
Watering: Allow the top 2–3 cm of soil to dry out; water thoroughly, ensuring good drainage. Overwatering is a common issue leading to root rot.


 
Humidity: Prefers moderate to high humidity; 50% or above is ideal. Avoid misting leaves directly to prevent fungal problems.


 
Temperature: Best grown in 18–26°C; shield from cold drafts or sudden temperature drops.


 
Fertilization: Feed monthly during active growth with a balanced water-soluble fertilizer at half strength.


 
Potting Mix: Use a well-aerated blend (orchid bark, perlite, and some potting soil) to keep roots healthy and avoid waterlogging.




Common Problems and Solutions



 
Yellowing Leaves: Typically due to overwatering; adjust frequency and ensure proper drainage.


 
Root Rot: Often caused by waterlogged soil; repot in fresh mix, removing affected roots.


 
Pests: Mealybugs, spider mites, and aphids; tackle infestations with insecticidal soap , neem oil, or use beneficial insects.


 
Browning Leaf Tips: May result from low humidity or too much direct sunlight; moderate conditions accordingly.




Additional Growing Tips



 
Training: Encourage vines to climb a decorative support, or let them cascade gracefully from a hanging pot.


 
Propagation: Root stem cuttings in water or a moist mix, ensuring at least one node is submerged. Transplant once roots form.


 
Cleaning: Wipe leaves with a soft, damp cloth to remove dust and maintain their brilliant speckling.
