Hoya Erythrina

Hoya erythrina is a beautiful and somewhat uncommon species of Hoya with thick, slightly fuzzy leaves and striking clusters of star-shaped flowers. It’s an epiphytic tropical plant, so it thrives in conditions that mimic its native Southeast Asian environment.

Here’s a complete care guide for Hoya erythrina:

🌤️ Light

• Bright, indirect light is best.

• Can tolerate some direct morning sun, but avoid harsh afternoon sun as it may scorch the leaves.

• If indoors, east- or north-facing windows are ideal; if using grow lights, aim for ~12-14 hours/day.

💧 Watering

• Let the top 2–3 inches of soil dry out before watering.

• During the growing season, water thoroughly when dry.

• In cooler months, reduce watering significantly.

• Always ensure good drainage to prevent root rot.

🌡️ Temperature & Humidity

• Prefers warm temperatures: 18–29°C (65–85°F)
  

• Loves high humidity: 60%+ is ideal, but will adapt to average indoor levels.

• Consider using a humidifier or placing the pot on a humidity tray.

🌱 Soil

• Use a chunky, airy, well-draining mix—examples:

  • 1 part orchid bark

  • 1 part perlite or pumice

  • 1 part coco coir or peat moss

• A pre-mixed aroid or Hoya mix also works well.

🌸 Fertilizer

• During growing season 

  • Use a balanced or bloom-boosting fertilizer every 2–4 weeks.

  • Look for NPK ratios like 10-10-10 or 5-10-5.
    

🪴 Potting & Repotting

• Hoyas like being a little root-bound, so repot only every 2–3 years or when roots are bursting out.

• Choose a pot only 1–2 inches wider when repotting.

• Always use pots with drainage holes.

✂️ Pruning & Support

• Minimal pruning needed—only remove dead or leggy stems.

• Provide a trellis or hoop; Hoya erythrina is a natural climber.

• Do not cut the peduncles (flower stalks) after blooms—they often rebloom from the same spot.

🐛 Pests to Watch For

• Mealybugs, spider mites, and aphids are most common.

• Wipe with neem oil or insecticidal soap if needed.

• Regularly inspect leaf undersides.

🌸 Blooming Tips

• Needs bright light and maturity (often 2–3 years or more) to bloom.

• Maintain consistent watering and don’t move it too much when it sets buds.

• High humidity and regular feeding help encourage flowers.
