Hoya clemensiorum Kalimantan (Clone 1) Care Guide:



 
Light Requirements: Prefers bright, indirect light. Direct sunlight can scorch the leaves; low light may slow growth and reduce contrast.


 
Watering: Allow the top 2-3 cm of soil to dry out before watering. Overwatering may lead to root rot; reduce frequency in cooler months.


 
Humidity: Moderate humidity (around 40-60%) is sufficient. Avoid direct misting on the leaves to prevent fungal issues.


 
Temperature: Ideal range is 18°C to 26°C. Avoid cold drafts and temperatures below 15°C.


 
Soil: Use a well-draining, airy mix (e.g., orchid bark, perlite, and coco coir) with a slightly acidic to neutral pH (6.0–7.0).


 
Feeding: Feed with a balanced liquid fertilizer diluted to half strength every 4-6 weeks during the growing season. Avoid over-fertilization.




Common Issues and Solutions:



 
Yellowing Leaves: May indicate overwatering or poor drainage; adjust watering frequency accordingly.


 
Root Rot: Occurs with waterlogged soil; use a well-draining mix and let the soil dry between waterings.


 
Drooping Leaves: Often due to underwatering or sudden temperature changes; check soil moisture and adjust care.


 
Pests: Watch for spider mites, mealybugs, and scale; treat with insecticidal soap , neem oil, or use beneficial insects if necessary.




Further Tips for Success:



 
Pruning: Regularly prune leggy or damaged stems to promote bushier growth.


 
Repotting: Repot every 2-3 years or when the plant becomes root-bound, using a slightly larger pot with fresh, well-draining soil.


 
Support: Provide a trellis or stake to accommodate its climbing nature and showcase its foliage.
