Care
Watering
Keep the substrate consistently moist without waterlogging. Water regularly during the growing season (spring-summer), reducing slightly in autumn-winter. This fern prefers high ambient humidity: mist the foliage 2 to 3 times per week or place the plant on a tray with water and pebbles.
Light and exposure
Place this fern in indirect light, away from direct sunlight which can scorch the delicate fronds. It tolerates partial shade well and thrives near a north-facing window or in a well-lit interior. Avoid cold drafts and sudden temperature fluctuations.
Substrate and repotting
Use a light, well-draining mix made of peat, leaf mold, and perlite or fine bark. Repot in spring every 2-3 years into a slightly larger pot. Be careful not to bury the crown of the plant.
Fertilizing
Apply a balanced fertilizer (NPK 6-6-6 type or similar) diluted at moderate strength every 4 to 6 weeks during the growing season. Reduce or stop fertilizing in autumn-winter. Ferns tolerate excess fertilizer poorly: it's better to under-fertilize than to over-fertilize.
Pruning and maintenance
Regularly remove dead or yellowing fronds above the base to encourage new frond growth. Don't unnecessarily prune healthy fronds. Dust the foliage with a soft damp sponge to maintain good transpiration.
Diseases and pests
Watch for spider mites and scale insects, which are favored by low humidity. In case of light infestation, increase misting and rinse with lukewarm water. Overly wet substrate can cause root rot: improve drainage if needed.
Did you know?
Lecanopteris pustulata is a fascinating epiphytic fern: it grows naturally on trees in the humid forests of Southeast Asia, which is why its fronds are adapted to life in the air. Its name 'pustulata' refers to the small pustules visible on its fronds, a particular botanical adaptation to its tropical habitat.
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.
