Hoya rundumensis 'Splash' Care Guide
To ensure that your Hoya rundumensis ‘Splash’ remains healthy and thriving, follow these care tips:
 
Light: Provide bright, indirect light for optimal growth. While it can tolerate some direct sunlight, too much can cause leaf burn. Avoid placing it in low-light conditions, which may inhibit its growth and flowering.
Watering: Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering frequency during the cooler months but avoid letting the soil dry out completely. Use well-draining soil to prevent root rot.
Humidity: Hoya rundumensis ‘Splash’ enjoys moderate to high humidity. While it can tolerate average indoor humidity, a slight increase will promote better growth.
Temperature: Keep the plant in a warm environment, ideally between 18-26°C. It should be protected from cold drafts and temperatures below 10°C, which can cause damage.
Fertilizing: Feed with a balanced, diluted liquid fertilizer every 4-6 weeks during the growing season. Avoid over-fertilizing, as this can lead to salt buildup in the soil.
Pruning: Prune sparingly to maintain its shape. Remove any dead or damaged leaves to encourage healthy growth.
 
 
Common Issues and Solutions
Even though Hoya rundumensis ‘Splash’ is generally easy to care for, it can still face some challenges. Here are common issues and solutions:
 
Yellowing Leaves: Overwatering is the most common cause of yellowing leaves. Ensure the soil dries out slightly between waterings and use a well-draining mix.
Root Rot: Caused by consistently waterlogged soil. Use a well-draining potting mix and ensure the pot has drainage holes. Allow the soil to dry out between waterings.
Pests: Watch out for common pests like spider mites, mealybugs, and scale. Treat infestations promptly with insecticidal soap or neem oil, and regularly inspect your plant for early signs of trouble.
Dropping Leaves: Sudden leaf drop can be due to changes in temperature or light conditions. Gradually acclimate the plant to new environments and avoid drastic changes.
 
 
Additional Growing Tips for Hoya rundumensis 'Splash':
 
Propagation: This Hoya is easily propagated through stem cuttings. Select a healthy stem with at least two leaves and nodes, and place it in water or a well-draining propagation mix until roots develop.
Support for Vining: As a natural climber, Hoya rundumensis ‘Splash’ will benefit from a trellis or stake. This support will help it grow in a more natural, vertical manner, showcasing its beautiful foliage.
Potting and Repotting: Use a well-draining mix specifically designed for epiphytes. Repot only when the plant has outgrown its pot, as Hoyas prefer being slightly root-bound.
 
Researching the natural habitat of Hoya rundumensis ‘Splash’ can provide valuable insights into its care.
