Care
Watering
Keep the substrate moist without waterlogging, especially during the growing season. Water regularly with soft or filtered water, ideally non-chalky. In winter, reduce watering slightly while maintaining some moisture. Ferns dislike dry air: mist the foliage regularly.
Light and exposure
Place your plant in indirect light, away from direct sun which scorches delicate fronds. A spot near a north or east-facing window, or away from a south-facing window, works perfectly. Avoid complete darkness which slows growth.
Substrate and potting mix
Use a light mix based on leaf mould, sphagnum or peat, enriched with perlite or fine gravel to improve drainage. An airy structure is essential to prevent root suffocation. Check that water drains well from the bottom of the pot.
Fertiliser
Apply a balanced, diluted fertiliser every 3 to 4 weeks during the growing period (spring-summer). Reduce frequency by half in autumn and stop in winter. Ferns need little feeding; prefer moderate regular application to overfeeding.
Pruning and maintenance
Remove dead, yellowed or damaged fronds regularly at the base of the plant. Gently clean the foliage with a damp cloth to prevent dust build-up. No drastic pruning needed: the fern adopts its shape naturally.
Pests and diseases
Watch for scale insects and spider mites, favoured by dry air. If infestation occurs, increase humidity and treat with soft soap. Excess substrate moisture can lead to root rot; ensure good drainage and air circulation regularly.
Did you know?
Adiantum aethiopicum, or African Maidenhair Fern, owes its scientific name to its extraordinarily delicate fronds that recall the fine hair of the goddess Venus. Traditionally, several Adiantum species were used in African herbal medicine for various purposes, and this small fern remains highly prized by rare plant collectors for its almost unreal delicacy.
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.
