Hoya pubicalyx 'Silver Splash' - Growing and Care Tips:
To ensure your Hoya pubicalyx 'Silver Splash' thrives, it’s essential to replicate the conditions of its natural environment as closely as possible. Here are some straightforward care guidelines:
 
Light Requirements:
Prefers bright, indirect light. Direct sunlight can cause the leaves to scorch, while too little light can reduce the vibrancy of the variegation.
Variegated Hoyas like this cultivar tend to show more intense colors under bright conditions, but avoid prolonged exposure to direct sunlight to prevent leaf burn.
Watering:
Allow the top 2-3 cm of soil to dry out between waterings. Overwatering can lead to root rot, a common issue with Hoyas.
Use a well-draining potting mix to prevent water from sitting around the roots.
Humidity:
Thrives in higher humidity levels, but can adapt to average indoor conditions.
Avoid misting directly onto the leaves as it may cause fungal issues.
Temperature:
Ideal temperatures range between 18-26°C. Avoid placing the plant near cold drafts or sudden temperature changes.
Fertilization:
Feed with a balanced, water-soluble fertilizer once a month during the growing season. Avoid over-fertilizing, which can cause salt buildup in the soil.
Potting Mix:
Use a well-draining mix suitable for epiphytes, such as a combination of orchid bark, perlite, and a small amount of peat or coco coir.
 
 
Common Problems and Solutions:
Despite being a relatively hardy plant, Hoya pubicalyx 'Silver Splash' can encounter a few common issues. Here’s how to address them:
 
Yellowing Leaves:
This could be due to overwatering. Check the soil moisture and reduce watering frequency if necessary.
Root Rot:
Typically caused by waterlogged soil. Repot with fresh, well-draining mix and prune away any affected roots.
Pests:
Watch out for mealybugs, spider mites, and aphids. Use a mild insecticidal soap or neem oil solution to treat infestations.
Browning Leaf Tips:
This can be a result of low humidity or too much direct sunlight. Adjust the plant’s position and monitor humidity levels.
 
 
Additional Growing Tips:
To achieve the best growth and vibrant foliage, consider the following:
 
Training: Use a trellis or support structure to train the plant’s vines, encouraging a lush, cascading growth habit.
Propagation: Hoya pubicalyx is easy to propagate from cuttings. Place stem cuttings in water or soil, ensuring at least one node is submerged.
Cleaning: Wipe the leaves gently with a damp cloth to remove dust and allow for better photosynthesis.
Placement: Ideal for locations with filtered light, such as near a north or east-facing window. Ensure the plant receives sufficient light for maintaining its variegation, but avoid harsh, direct rays.

Etymology:
The genus name Hoya was given in honor of Thomas Hoy (c. 1750–1822), an English gardener and botanist who made significant contributions to horticulture. His work and passion for plant cultivation, particularly with epiphytic and exotic species, were recognized by his contemporary, botanist Robert Brown, who named the genus after him.
