Actiniopteris australis Care Guide
Light
- Prefers bright, indirect light.
- Can adapt to moderate light but avoid strong direct sun, which can scorch fronds.
Watering
- Keep the soil consistently moist but never soggy.
- Allow the top 1–2 cm of soil to dry slightly between waterings.
Humidity
- Thrives in moderate to high humidity (50–70%).
- Use a humidifier, group plants together, or place on pebble trays if indoor air is dry.
Temperature
- Best between 18–24 °C.

- A mix with peat moss, perlite, and fine orchid bark works well.
Repotting
- Repot annually or when roots fill the pot, using a slightly larger container with drainage holes.
Fertilizing
