Phalaenopsis Orchid Culture

Phalaenopsis, also known as Moth Orchids, are loved for their long-lasting flowers that can bloom for 2–3 months. A healthy plant may even rebloom from the same flower spike.

Light

  • Bright, indirect light.
  • Avoid direct sunlight.
  • Ideal for shaded balconies or indoor spaces with good natural light.

Water

  • Keep the roots consistently moist but never waterlogged.
  • Water thoroughly when the media starts to dry.
  • Avoid water collecting in the crown to prevent crown rot.

Temperature

  • Best grown between 18°C–32°C.
  • Move to a cooler location if temperatures exceed 32°C.
  • Can tolerate temperatures as low as 10°C.

Humidity

  • Prefers 50–80% humidity.
  • Low humidity and hot weather can dehydrate the plant.
  • Requires regular care, especially during summer.

Potting & Fertilizer

  • Use a coarse, well-draining orchid mix such as coco chips or bark.
  • Grow in orchid pots or hanging baskets for better airflow.
  • Use a balanced orchid fertilizer after flowering and switch to a high-potassium fertilizer before the blooming season to encourage healthy spikes and abundant flowers.
