How to Water Hoya sigillatis 'Silver'
 
Let the top 2–3 cm of substrate dry before rewatering.
 
Never let the plant sit in standing water. Use drainage holes and avoid soggy saucers.
 
Reduce frequency if light or temperatures drop significantly.
Humidity, Airflow, and Temperature
 
Prefers 60–70% humidity but adapts to normal room levels if not too dry.
 
Keep within 18–25 °C and away from heat sources or cold windows.
 
Ensure light airflow to discourage fungal issues and pests.
Soil and Potting Tips
 
Use a well-draining mix of orchid bark, perlite, and a small amount of coco coir.
 
Repot every 2–3 years or if the mix breaks down and compacts.
Fertilizing for Healthy Growth
 
Feed monthly with a balanced, low-nitrogen liquid fertilizer when the plant is actively growing under good light.
 
Never fertilize dry roots — always water lightly first.
Pruning and Propagation
 
Trim long vines to promote bushier growth and control shape.
 
Propagate using 2–3 node stem cuttings in water or moss. Bright light and high humidity help root development.
