Oceaniopteris gibba Care Guide
This fern flourishes when provided with the right light, water, humidity, and nutrients.

Placement & Light
Prefers bright, indirect light.
Avoid direct sun, which can scorch the fronds.
Can tolerate semi-shade, though growth may slow.
 
Watering
Keep soil consistently moist but not waterlogged.
Use filtered or rainwater to prevent leaf spotting from minerals.
Ensure good drainage to prevent root rot.
 
Humidity & Temperature
Requires high humidity (60-80%) to thrive.
If air is dry, use a humidifier or group with other moisture-loving plants.
Prefers temperatures between 18-28°C. Avoid exposure to cold drafts or temperatures below 15°C.
 
Soil & Pot Choice
Best in well-draining, organic-rich soil (peat, perlite, and compost mix).
Use a deep, well-draining pot with multiple drainage holes.
Avoid excessively large pots that retain too much moisture.
 
Repotting & Fertilizing
Repot every 2-3 years to refresh the soil.
Fertilize monthly with a balanced liquid fertilizer, diluted to half-strength.
 
Pruning & Propagation
Trim yellowing or dead fronds to encourage new growth.
Propagate by division during repotting or by spores.
 
Semi-Hydroponics & Hydroponics
Can adapt to semi-hydroponic setups in LECA or perlite, as long as moisture is carefully regulated.

A sign of excess moisture and poor aeration.
Solution: Improve drainage, use aerated soil, and adjust watering habits.
