Care
Watering
The areolated woodwardia appreciates constantly moist soil: maintain regular moisture without waterlogging it. In summer, increase watering frequency, especially for potted plants. In winter, reduce watering slightly but don't let the substrate dry out completely.
Exposure
This fern prefers partial shade or dappled light. Avoid intense direct sun, which would dry out the foliage. A location under tree cover or in indirectly lit conditions suits it perfectly.
Soil and substrate
Use a mix rich in organic matter: potting soil, peat, or leaf compost. Ensure the soil remains well-draining to prevent rhizome rot. Adding perlite or sand will promote aeration.
Fertilization
Apply a low-nitrogen fertilizer once or twice monthly during the growing season (spring-summer). A fern with soil rich in organic matter requires less supplementation than a flowering plant.
Pruning and maintenance
Regularly remove dried or damaged fronds at the base of the petiole. In late winter or early spring, eliminate dead leaves to stimulate new growth.
Pests and diseases
Watch for spider mites and mealybugs indoors. Excess moisture can promote fungal rot: ensure good air circulation. Treat promptly with natural insecticide or soap solution if needed.
Did you know?
The areolated woodwardia is characterized by its pinnate fronds displaying very distinct areoles (distinct cellular spaces), hence its botanical name. This fern was once more common in France in nineteenth-century Victorian collections, where Victorians passionately collected exotic and native ferns to adorn their greenhouses.
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.
