Dicksonia squarrosa

The rough tree fern flourishes in conditions of high humidity and consistent moisture. To keep the soil evenly moist without causing waterlogging, water the plant twice a week. Using mulch can help retain moisture and simulate its natural forest habitat, as the fern typically grows in shaded outdoor areas.

The rough tree fern does best with a mix of shade and light, matching its natural habitat in forest understories. Its health can decline with excessive exposure to strong sunlight, and a complete lack of light is also harmful to its growth. Moderate light intensity is suitable at every stage of development.

Rough tree fern originates from habitats that experience wide temperature fluctuations, typically between 68 and 95°F (20 and 35°C). To replicate these conditions, expose it to similar temperatures, which may require adjustments as the seasons change.

To ensure the rough tree fern thrives, repot it every 2-3 years during the spring. Use a slightly larger pot with good drainage. After repotting, keep the soil moist and well-draining, and protect the fern from intense sunlight. Be gentle with the roots to promote healthy growth.

The rough tree fern is characterized by its slender trunk and lush fronds. The best time to prune dead fronds is in early spring. Be sure to use clean tools to prevent the spread of disease. Concentrate on removing the lower fronds to enhance air circulation, maintain the plant's appearance, and reduce the risk of fungal issues. This will help promote a robust and thriving plant.
