FAQs

Is the Asplenium Scolopendrium 'Angustatum' suitable for indoor growing?

While it prefers cooler, shaded outdoor conditions, it can be grown indoors in a bright, indirect light location with high humidity. Ensure consistent moisture and good drainage.

Keep the soil consistently moist but not waterlogged. Water when the top inch of soil feels dry. This may be daily in hot weather or less frequently in cooler, humid conditions.

Can this fern tolerate frost?

As an evergreen fern, it can tolerate light frost. In very cold climates, provide a layer of mulch around the base for winter protection.

What is the best soil type for this fern?

It prefers moist, well-drained soil rich in organic matter. It tolerates slightly alkaline to neutral soils but can also handle slightly acidic conditions.

When is the best time to plant Asplenium Scolopendrium 'Angustatum'?

The best times to plant are spring or early autumn, allowing the plant to establish its roots before extreme weather conditions.

How large does this fern typically grow?

The Asplenium Scolopendrium 'Angustatum' typically grows to a height and spread of about 30-45 cm (12-18 inches).

Troubleshooting

Fronds turning brown or crispy

This is likely due to insufficient moisture or exposure to direct sunlight. Increase watering frequency and ensure the plant is in a fully shaded location.

Yellowing leaves

May indicate overwatering or poor soil drainage. Check soil moisture and ensure water can drain away freely. If soil is too wet, consider repotting in better-draining soil.

Slow growth

Ensure the plant is receiving adequate moisture and nutrients. Consider amending the soil with compost or applying a light feed in spring if growth seems stunted.

Pest or disease problems

This fern is generally pest and disease resistant. Inspect for common garden pests like slugs or snails and address as needed. Ensure good air circulation to prevent fungal issues.

Pros and Cons

Pros

  • Provides year-round visual interest due to its evergreen nature.
  • Unique narrow fronds add architectural appeal to garden designs.
  • Versatile for various planting locations including borders, rockeries, and containers.
  • Low maintenance once established in suitable conditions.
  • Complements woodland and shaded garden aesthetics.

Cons

  • Requires consistent moisture; may struggle in very dry conditions.
  • Prefers well-drained soil; susceptible to root rot if waterlogged.
  • Best suited for shaded environments; may scorch in direct sunlight.
  • Specific soil pH preference may require amendment in some gardens.

Setup, Compatibility & Care

Planting:

  1. Choose a location that receives partial to full shade.
  2. Ensure the soil is rich in organic matter and drains well.
  3. Amend soil to be slightly alkaline to neutral if necessary.
  4. Plant the fern at the same depth it was in its original pot.
  5. Water thoroughly after planting.

Care:

  • Watering: Keep the soil consistently moist but not waterlogged. Water regularly, especially during dry periods.
  • Soil: Prefers moist, well-drained soil with a good amount of organic matter. Avoid heavy clay soils that retain too much water.
  • Sunlight: Protect from direct sunlight, which can scorch the fronds.
  • Fertilizing: Generally not required if planted in rich soil. A light feeding with a balanced liquid fertilizer in spring can be beneficial if growth is slow.
  • Pruning: Remove any dead or damaged fronds at the base as needed to maintain appearance.

Compatibility:

  • Pairs well with other shade-loving perennials such as Hostas, Ferns, Heucheras, Astilbes, and Epimediums.
  • Suitable for planting in containers with good drainage.
  • Tolerant of a range of soil pH levels, though it thrives in slightly alkaline to neutral conditions.
