How to Care for Your Hoya rundumensis 'Splash'

Light: Provide bright, indirect light for optimal growth. While some direct sunlight is acceptable, prolonged exposure can cause leaf burn. Avoid low-light conditions, as this may inhibit growth and flowering.
Watering: Water thoroughly when the top 2-3 cm of soil feels dry. Ensure the soil is well-draining to prevent waterlogging, which can cause root rot. Reduce watering frequency during cooler months but never let the soil dry out completely.
Humidity: Hoya rundumensis 'Splash' thrives in moderate to high humidity. While it tolerates average indoor humidity, increasing humidity levels will enhance its growth, especially during the growing season.
Temperature: Keep the plant in a warm environment, ideally between 18-26°C. Avoid placing it in drafty areas or exposing it to temperatures below 10°C, which can damage the plant.
Fertilizing: Use a balanced, diluted liquid fertilizer every 4-6 weeks during the growing season. Be cautious not to over-fertilize, as it can lead to salt buildup and soil toxicity.
Pruning: Prune sparingly to maintain shape. Remove dead or damaged leaves to encourage healthy new growth and keep the plant looking tidy.



Common Problems with Hoya rundumensis 'Splash' and How to Solve Them

Yellowing Leaves: Usually caused by overwatering. Make sure the soil dries slightly between waterings and use well-draining soil.
Root Rot: Root rot can occur from consistently wet soil. Use a well-draining mix and ensure the pot has drainage holes. Allow the soil to dry out between waterings.
Pests: Common pests include 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 occur due to drastic changes in temperature or light conditions. Gradually acclimate the plant to new environments and avoid sudden changes.



Propagation Tips for Hoya rundumensis 'Splash'

Stem Cuttings: 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. Using rooting hormone can enhance rooting success.
Support for Vining: As a natural climber, it benefits from a trellis or stake. Providing support helps the plant grow vertically and showcases its beautiful foliage.
Potting and Repotting: Use a well-draining potting mix, designed for epiphytes. Repot only when the plant has outgrown its pot, as Hoyas prefer being slightly root-bound.
