Watering. Keep soil consistently moist but not soggy. Water when the top inch of soil feels dry. Mist regularly to maintain humidity, especially in dry indoor environments.
Fertilizing. Feed monthly during the growing season (spring and summer) with a balanced, diluted liquid fertilizer. Reduce feeding in fall and winter when growth slows.
Asplenium antiquum is a hardy fern that thrives in low to medium light and prefers consistently moist soil. It can suffer if overwatered or placed in direct sunlight. Regular misting helps maintain humidity, and occasional pruning removes dead fronds to keep it healthy.
