🌱 How to Care for Hoya Burtoniae to Prevent Leaf Spot?

💧 How to Water

Let the mix dry out about halfway before watering again, then soak thoroughly until water runs from the drainage holes. Hoya burtoniae stores moisture in its leaves and tolerates brief dryness far better than soggy roots — reduce watering frequency in winter.

☀️ Lighting

Give it bright, indirect light near an east-facing window or a few feet back from a south or west window; a couple hours of gentle morning sun deepens the red blush on the leaves, but harsh afternoon sun can scorch them.

🪴 Ideal Soil

Pot in a chunky, airy, epiphytic mix of orchid bark, perlite or pumice, and coconut coir so water drains fast and roots get plenty of air — a dense, moisture-retentive potting soil invites root rot.
