Treefern are large, tree-like ferns favoring warm, moist environments. Basic care requirements involve dappled sunlight, consistent moisture without waterlogging, and well-draining, organically rich soil. Protection from strong winds and support for optimal growth is crucial. Common challenges include scale insects and fungal infections, with sensitivity to overexposure to sunlight and dry conditions. Seasonally, treefern may require adjustments in watering to prevent frost damage and maintain humidity levels, with less water needed in winter. When growth slows in cooler months, less frequent care may be necessary.
