Improper-Growing-Conditions on birds nest fern
What's Happening
Asplenium nidus, with its broad glossy fronds forming a rosette 'nest', requires consistent medium light and humidity to maintain its tropical appearance. Inadequate light causes fronds to lose their deep green color and become leggy, while dry air damages the large leaf surface area.
How to Fix It
- 1
Place bird's nest fern in medium, indirect light - bright enough to read a newspaper but without direct sun rays
- 2
Maintain minimum winter temperature of 10-15°C (50-60°F); prefers temperatures at the warmer end of this range
- 3
Mist fronds weekly with tepid, lime-free water to maintain humidity around the large leaf surface
- 4
Use a light, moisture-retaining compost based on peat or peat substitute with added sand for drainage
- 5
Water regularly to keep compost moist but never waterlogged; ferns dislike standing in saturated soil
How to Prevent It
Position in consistent medium light away from direct sun; maintain moderate humidity and temperatures above 10°C (50°F); never allow compost to completely dry out.
