Expert tips
The key tip
This fern thrives in moist shade and really hates dry air. Keep the soil fresh (not waterlogged) and boost your mulch in summer, especially in dry continental climates.
The common mistake
In overly dry areas or afternoon sun, fronds brown out and struggle to recover.
The pro's trick
Mix decomposed dead leaves into the planting soil to mimic cool forest soil.
Care
Watering
The lady fern loves constantly moist soil without being waterlogged. Water regularly during the growing season (spring-summer), particularly during prolonged dry spells. In winter, reduce watering but don't let the soil dry out completely.
Light
Place this fern in partial shade or full shade. It tolerates shaded, humid areas, typically under trees or against a north-facing wall. It fears direct sun which would burn its delicate fronds.
Soil
Choose a substrate rich in organic matter, well-draining but moisture-retentive. Improve the soil with compost or peat before planting. Slightly acidic to neutral pH is ideal.
Pruning and cleaning
No pruning is necessary. Simply remove dead or damaged fronds in late winter or early spring to encourage new frond emergence.
Fertilizer
A light application of balanced fertilizer in spring is sufficient. Prefer diluted organic fertilizer or a light compost application around the clump. Avoid excess which could upset the balance of the forest environment.
Diseases and pests
The lady fern is generally hardy against diseases. Watch out for excess moisture which can encourage root rot. Regularly air out the foliage to limit fungi. Scale insects and spider mites are rare but possible in overly dry conditions.
Did you know?
The lady fern long fascinated the Victorians, who developed hundreds of varieties for their shaded gardens. Its name "lady" contrasts with the "male fern" (Dryopteris filix-mas): this ancient distinction is based on the fineness of the fronds, females being reputed more delicate and elegant. Today it remains a star of woodland gardens and fresh floral arrangements.
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.
