With its ancient lineage and striking appearance, Dicksonia squarrosa is a cherished addition to woodland gardens, ferneries, and shaded landscapes, where it creates a sense of enchantment and tranquility. 

Description: 

Plant Size: Dicksonia squarrosa typically grows as a medium to large-sized fern, with a trunk that can reach significant heights over time. The fronds emerge from the crown of the trunk, forming a spreading canopy of lush foliage. 6m x 3m. 

Fronds: The fronds of Dicksonia squarrosa are the defining feature of the plant, with large, bipinnate leaves that are deeply lobed and finely divided. The fronds can reach lengths of several feet and have a feathery appearance, adding grace and elegance to the fern. 

Trunk: The trunk of Dicksonia squarrosa is thick and fibrous, covered in a dense layer of adventitious roots known as “hairy roots.” These roots help support the fern and absorb moisture from the surrounding environment, contributing to its overall health and vigor. 

Growing and Caring: 

Preferred Climate: Dicksonia squarrosa thrives in cool, temperate climates with mild, moist conditions. It prefers partial to full shade and is well-suited for growing under the canopy of larger trees or in sheltered garden areas. 

Sunlight: While it can tolerate some dappled sunlight, Dicksonia squarrosa prefers shaded conditions, particularly during the hottest part of the day. Direct sunlight can scorch the fronds and cause them to become discoloured or damaged. 

Soil Requirements: Well-drained, organic-rich soil is ideal for Dicksonia squarrosa, with a slightly acidic to neutral pH. The soil should be kept consistently moist but not waterlogged, as excessive moisture can lead to root rot and other issues. 

Watering: Regular watering is essential to maintain soil moisture and humidity levels for Dicksonia squarrosa. Water deeply and thoroughly, ensuring that the soil remains consistently moist but not waterlogged. Mulching around the base of the fern can help retain moisture and regulate soil temperature. 

Pruning: Pruning is generally not necessary for Dicksonia squarrosa, except to remove dead or damaged fronds or to tidy up the appearance of the plant. Avoid cutting into the trunk, as this can damage the growing point and lead to issues with the fern’s growth. 

Fertilisation: Dicksonia squarrosa benefits from occasional Fertilisation during the growing season, using a balanced, slow-release fertilizer formulated for ferns or acid-loving plants. Follow the manufacturer’s recommendations for application rates and frequency. 

Mulching: Applying a layer of organic mulch around the base of the fern helps retain moisture, suppress weeds, and regulate soil temperature, creating a favorable growing environment for Dicksonia squarrosa. 

Pest and Diseases: Dicksonia squarrosa is relatively resistant to pests and diseases, but occasional issues such as scale insects or fungal infections may occur, particularly in poorly ventilated or overly damp conditions. Regular inspection and appropriate pest management practices can help prevent problems. 

Attractive Features of Dicksonia squarrosa for Gardens: 

Architectural Presence: The tall, slender trunk and gracefully arching fronds of Dicksonia squarrosa create a striking focal point in shaded garden settings, adding a sense of drama and elegance to woodland landscapes. 

Prehistoric Charm: With its ancient lineage and primitive appearance, Dicksonia squarrosa evokes a sense of prehistoric wonder, transporting gardeners to a bygone era and adding a touch of enchantment to outdoor spaces. 

Shade Tolerance: Dicksonia squarrosa is well-adapted to growing in shaded conditions, making it an ideal choice for gardens with limited sunlight or for creating lush, tropical-themed landscapes in sheltered areas. 

Low Maintenance: Once established, Dicksonia squarrosa is relatively low-maintenance, requiring only regular watering, occasional Fertilisation, and minimal pruning to maintain its health and appearance, making it an excellent choice for busy gardeners. 

Tropical Ambiance: The lush, feathery fronds of Dicksonia squarrosa and its towering presence create a tropical ambiance in garden settings, allowing gardeners to experience a taste of the tropics even in cooler climates, where other tropical plants may struggle to thrive.
