Keep the soil consistently moist and avoid letting it dry out completely. Watch for browning frond tips, which often signal that the air is too dry or the soil needs more water. It prefers a spot sheltered from harsh winds and direct sun.

Arrosage
Keep the soil evenly moist but not waterlogged.
Engrais
Apply a balanced liquid fertilizer diluted to half strength during the growing season.

Remove dead or damaged fronds in late winter or early spring before new growth appears.

Repot only when the plant becomes root bound or the soil structure breaks down.

Signes qu'il faut rempoter

  • Roots growing out of the drainage holes
  • Water running straight through the pot
  • Stunted growth during the active season

Sécurité

Humains
The plant contains small amounts of filicin which can be toxic if ingested in large quantities.
Enfants
Keep away from small children as the fronds can be tough and the plant is not for consumption.
Allergènes de contact
The spores can sometimes cause mild skin irritation in sensitive individuals.
Allergènes aéroportés
The fine spores released in late summer may trigger respiratory sensitivity in those prone to fern allergies.
Comestibilité
This fern is not considered edible and may cause digestive distress if consumed.

Multiplication
division, spores
Quand planter
spring, autumn
Hivernage
Leave the old fronds on the plant until spring to protect the crown from frost. Clear away dead debris once new growth appears.
En pot
It grows well in large pots that provide enough room for the root system to expand.

Division

  1. 1. Carefully dig up the clump in early spring.
  2. 2. Use a sharp spade to divide the root mass into smaller sections.
  3. 3. Replant the divisions immediately in moist, organic soil.

Pair this fern with other moisture loving woodland plants to create a lush, low maintenance shade garden.

Bonnes associations

  • Hosta — They share similar requirements for shade and moisture.
  • Lamprocapnos spectabilis — The delicate flowers contrast beautifully with the coarse fern foliage.

Espèces similaires

  • Male fern — It is a larger, more upright relative that thrives in similar conditions.

Ce qu'on demande souvent

Does this fern stay green all year?
It is semi evergreen, meaning it keeps its foliage through mild winters but may die back in colder climates.
How do I propagate it?
The easiest way is to divide the root clumps in early spring.

D'où vient le nom

The name Dryopteris comes from the Greek words for oak and fern, while dilatata refers to the expanded or broadened fronds.

Bon à savoir

  • It is often called the broad buckler fern due to the shape of its spore cases.
  • The fronds are tripinnate, giving them a lovely lacy appearance.
  • It prefers acidic, moist soil conditions.
