Care
Regular watering
Keep the substrate consistently moist, but without waterlogging. Water moderately in winter and more generously during active growth periods. Use soft or filtered water, as ferns appreciate low lime content. Mist the foliage regularly to recreate the tropical ambient humidity.
Indirect light
Place your fern in bright, indirect light, away from direct sunlight which would scorch the fronds. An East or Northeast-facing exposure is ideal. It also tolerates semi-shaded areas but fears prolonged darkness.
Removal of dead fronds
Regularly remove yellowed, damaged or withering fronds at the base of the plant. This operation promotes air circulation and encourages new frond growth. Avoid drastic pruning; the fern grows naturally in a clumping form.
Aerated and rich substrate
Use a light mix composed of potting soil, coconut fiber and perlite or fine bark to ensure good drainage. A slightly acidic pH is recommended. Repot in spring if the plant becomes root-bound, every 2 to 3 years.
Moderate nutrient supply
Apply diluted, low-nitrogen fertilizer once a month during the growing season (spring-summer). Reduce or stop fertilizing in autumn and winter. Ferns prefer light feeding; excess fertilizer causes foliage burn.
Pest prevention
Watch out for scale insects, spider mites and aphids, which thrive in dry air. Maintain high ambient humidity to prevent these issues. In case of mild infestation, rinse the foliage with soft water; isolate the plant if damage is significant.
Did you know?
Microlepia marginata, called the 'marginal fern' in reference to the distinctive arrangement of its sori (reproductive organs), long fascinated Victorian fern collectors in the 19th century. Unlike flowers, ferns reproduce through microscopic spores lodged under the fronds, making them among the oldest vascular plants on our planet.
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.
