Care
Watering
Keep the soil consistently moist but not waterlogged, particularly during spring and summer growth. In dry periods, increase watering frequency. In autumn and winter, reduce watering as the fern goes dormant.
Exposure and light
This fern appreciates shade to partial shade, ideal for areas under trees or near a north-facing wall. Avoid direct sun which dries out the delicate foliage. Indirect and filtered light promotes harmonious development.
Soil preparation
Enrich the soil with compost or peat to improve moisture retention and structure. Good substrate aeration is essential to prevent rhizome asphyxiation. A slightly acidic to neutral pH is preferred.
Fertilization
Apply a balanced diluted fertilizer in spring when growth resumes. A single application is usually sufficient during the growing season. Avoid excess fertilizer which can promote overly vigorous growth and weaken the fern.
Maintenance and pruning
Remove dead or damaged fronds as they appear. In late autumn, you can cut the dried fronds at ground level before winter dormancy. Gentle foliage cleaning improves photosynthesis.
Pests and diseases
This fern is generally robust. Watch for red spider mites in overly dry environments and slugs in very humid conditions. Good drainage and aeration prevent most fungal problems.
Did you know?
The name "hexagonoptera" refers to the characteristic shape of its leaf segments which have a geometry close to hexagonal form, a particularity that long intrigued botanists. This North American fern was traditionally used by indigenous peoples for its ornamental properties and its presence marked humid and shaded forest areas, making it an excellent ecological indicator of preserved environments.
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.
