The Philippine Hoya Society is active and passionate. Native species like Hoya mindorensis, H. buotii, and H. halconensis are internationally sought after.

Care Guide
Keep your Hoya healthy and thriving.
Bright indirect light (some species tolerate direct morning sun). Position your hoya where it receives the right amount of light for healthy growth in Philippine conditions.
Let soil dry between waterings — epiphytic roots rot easily in wet conditions. Water less in cooler months. Adjust frequency during the Philippine rainy season when humidity is higher and soil stays moist longer.
Ideal temperature range: 20-32°C (most species thrive in Philippine conditions). 60-80% — ideal in Philippine humidity. Mist in AC rooms.
Diluted orchid fertilizer monthly during active growth. Phosphorus-heavy feed encourages blooming.
NEVER cut off old flower stalks (peduncles) — hoyas re-bloom from the same spur year after year.
