Growing Conditions
Light
Jurassic Gold Fern thrives in partial to full shade. While it can tolerate some morning sun, it is crucial to protect it from the harsh afternoon sun, which can scorch its delicate fronds. Ideal planting locations include shaded garden beds, under trees, or in shaded areas of patios and balconies.
Soil
The ideal soil for Jurassic Gold Fern is well-drained and rich in organic matter. It prefers slightly acidic to neutral soil pH (5.5 to 7.0). Incorporating compost or well-rotted manure into the soil will enhance its fertility and drainage capabilities. This fern does not tolerate waterlogged conditions, so ensuring good drainage is essential to prevent root rot.
Watering
Jurassic Gold Fern requires consistent moisture to thrive. The soil should be kept evenly moist but not soggy. During the growing season (spring to fall), regular watering is necessary, especially during dry spells. Mulching around the base of the plant can help retain soil moisture and reduce the need for frequent watering. In winter, reduce watering but do not allow the soil to dry out completely.
Temperature and Humidity
Jurassic Gold Fern is hardy in USDA zones 5-8. It can tolerate temperatures down to -20°F (-29°C) but performs best in mild, cool climates. High humidity levels are beneficial for this fern, mimicking its natural woodland habitat. In dry climates, increasing humidity through misting or using a humidifier can help maintain healthy fronds.
Fertilizing
Feeding Jurassic Gold Fern with a balanced, water-soluble fertilizer in the spring and midsummer will promote vigorous growth. Use a diluted solution to avoid over-fertilization, which can damage the plant. Alternatively, applying a slow-release fertilizer in early spring can provide steady nutrients throughout the growing season.

Planting and Propagation
Planting
- Site Selection: Choose a location with partial to full shade and well-drained, humus-rich soil.
- Soil Preparation: Amend the soil with compost or well-rotted manure to enhance fertility and drainage.
- Planting: Dig a hole twice the width of the root ball and as deep. Place the fern in the hole, ensuring the crown is level with the soil surface. Backfill with soil and gently firm it around the roots.
- Watering: Water thoroughly after planting to settle the soil and eliminate air pockets.
Propagation
Jurassic Gold Fern can be propagated through division or spores.
Division
- Timing: The best time to divide is in early spring before new growth begins.
- Method:
- Carefully lift the fern clump from the ground.
- Use a sharp knife or spade to divide the clump into smaller sections, each with several fronds and a portion of the root system.
- Replant the divisions immediately in prepared soil and water well.
Spores
- Spore Collection: In late summer, collect mature spores from the underside of the fronds.
- Sowing:
- Fill a seed tray with a mixture of peat and sand.
- Sprinkle the spores evenly over the surface.
- Cover the tray with plastic to maintain high humidity.
- Place in a warm, shaded area and keep the soil moist.
- Transplanting: Once the young ferns have developed several fronds, transplant them into individual pots or directly into the garden.
Care and Maintenance

Pruning
Pruning Jurassic Gold Fern is minimal. Remove old or damaged fronds at the base to improve appearance and encourage new growth. In early spring, cut back any remaining old fronds to make way for fresh new growth.
Pests and Diseases
Jurassic Gold Fern is relatively pest and disease-resistant. However, it can occasionally be affected by:
- Slugs and Snails: These can chew on the fronds, causing unsightly damage. Use organic slug repellents or traps to manage infestations.
- Aphids: These small insects can cluster on new growth. Use insecticidal soap or neem oil to control them.
- Root Rot: This can occur in poorly drained soil. Ensure proper drainage and avoid overwatering.
Overwintering
In USDA zones 5-8, Jurassic Gold Fern is hardy and can be left in the ground over winter. In colder regions, mulch heavily around the base to protect the roots from freezing temperatures. In pots, move the fern to a sheltered location or indoors to prevent frost damage.
Companion Planting
Jurassic Gold Fern pairs well with other shade-loving plants, creating a lush and diverse garden bed. Consider planting it alongside:
- Hostas: Their large, bold leaves contrast beautifully with the delicate fronds of the fern.
- Astilbes: Their feathery plumes complement the fern’s texture and add vertical interest.
- Heucheras: The colorful foliage of Heucheras provides a striking contrast to the fern’s green and gold tones.
- Woodland Wildflowers: Plants like Trillium, Solomon’s Seal, and Jack-in-the-Pulpit enhance the woodland theme.
Landscaping Uses
Jurassic Gold Fern is versatile in the landscape, suitable for various garden styles and applications:
- Shade Gardens: Ideal for adding texture and color to shaded areas.
- Woodland Gardens: Perfect for creating a natural, forest-like setting.
- Borders and Edges: Use as a border plant along shaded paths and garden edges.
- Containers: Grows well in pots and containers, making it suitable for patios and balconies.
- Ground Cover: Forms a dense, low-maintenance ground cover in shaded areas.
