Hoya Polyneura Vietnam

Size: 15cm, comes in nursery pot

Hoya polyneura ‘Vietnam’, also known as the fishtail Hoya. This plant is a bit more delicate than other Hoyas, but with the right setup it’s stunning. Here’s a detailed guide:

🌱 Light

• Prefers bright, indirect light.

• Can tolerate some morning sun but avoid harsh afternoon rays, which can scorch leaves.

• Indoors, place near an east- or north-facing window or several feet back from a bright south-facing window.

💧 Watering

• Keep the soil slightly moist but never soggy.

• Water thoroughly when the top 1–2 inches of soil are dry.

• Reduce watering in winter when growth slows.

• Use filtered or rainwater if your tap water is very hard—H. polyneura can be sensitive to mineral buildup.

🪴 Soil

• Needs a loose, airy mix with excellent drainage.

• A good blend:

  • 40% orchid bark or chunky perlite

  • 30% peat moss or coco coir

  • 30% perlite or pumice

• Adding some horticultural charcoal can also help with drainage and prevent root rot.

🌡️ Temperature & Humidity

• Thrives at 65–80°F (18–27°C).
  

• Likes high humidity (60%+).

  • Use a pebble tray, humidifier, or group with other plants if your air is dry.

🌸 Fertilizing

• Feed with a balanced, diluted fertilizer every 4–6 weeks during the growing season (spring and summer).

• Switch to a bloom booster (slightly higher phosphorus) if you want to encourage flowering.

• Pause feeding in winter.

✂️ Pruning & Support

• Let vines trail or climb; the plant produces umbels of creamy, fragrant flowers on mature vines.

• Don’t cut off the spurs (the small stalks where flowers form), as it blooms from the same points.

⚠️ Common Issues

• Yellowing leaves → Overwatering or poor drainage.

• Crispy edges → Low humidity or underwatering.

• No flowers → Plant is too young, light is too low, or not enough fertilizer.
