Care
Watering
Keep the substrate moist but not waterlogged, especially during the growing season. Water regularly in summer and reduce watering in winter. Prefer soft water or rainwater to prevent lime buildup on the fronds.
Light exposure
This fern appreciates indirect, filtered light. Avoid direct sun exposure, which would scorch the delicate fronds. A spot near a north or east-facing window is ideal.
Substrate and soil
Use a mixture rich in organic matter: fern potting soil, peat, or coco fiber. Ensure excellent drainage to prevent rhizome rot. Slightly acidic pH is preferred.
Fertilization
Apply diluted, balanced liquid fertilizer once a month during the growing phase (April to September). Reduce fertilization in winter. Favor moderate applications rather than heavy ones for this delicate plant.
Pruning and maintenance
Regularly remove dead or damaged fronds at the base to encourage new growth. Gently clean the fronds with a soft, damp brush to prevent dust accumulation.
Pests and diseases
Watch for spider mites and mealybugs, particularly in dry air. Sufficient ambient humidity reduces these risks. If problems occur, treat quickly with gentle methods before considering chemical treatment.

The name 'Asplenium' comes from ancient Greek and literally means 'without a spleen,' as the ancients traditionally used them in remedies supposedly intended to cure spleen ailments.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
