Cyathea Australis Tree fern 5 Liter

Cyathea Australis (5 Litre)

Product Description Cyathea australis, commonly known as the Rough Tree Fern, is an architectural, ancient fern renowned for its impressive palm-like canopy and robust, fibrous trunk. Emerging from the crown in graceful unfurling croziers, the massive, finely divided arching fronds form a vibrant emerald-green umbrella of lush tropical foliage. The stout brown trunk is naturally clad in coarse, textured scales and the persistent bases of old leaf stems, lending striking prehistoric texture to any landscape.

Supplied established in a 5-litre nursery bag, this fast-growing specimen is ready to add immediate structural elegance and vertical interest to semi-shaded outdoor settings. It thrives as a stately understorey focal point, bringing woodland charm and verdant height to damp garden glades, filtered woodland walkways, tranquil shaded courtyard corners, and large patio containers.

Care & Maintenance

• Light: Position in dappled sunlight, bright filtered light, or soft morning sun. Ensure total shelter from harsh, direct midday summer rays to prevent frond scorch.
• Watering: Water deeply and regularly to maintain evenly moist soil. During warm, dry weather, hose down the fibrous trunk as well as the root zone, as aerial roots absorb moisture along the stem.
• Feeding: Feed every 4 to 6 weeks from spring through late summer with a balanced, diluted liquid seaweed or organic fern fertiliser applied to the root zone and trunk. Avoid pouring concentrated fertiliser directly into the crown.
• Mulching: Apply a thick layer of organic compost, pine bark, or leaf mulch around the base to retain root moisture and keep the root zone cool.
• Grooming: Trim away older, spent brown fronds close to the trunk using clean, sharp pruning shears to maintain a neat crown and encourage fresh fiddlehead development.
