ðą How to Care for Common finger-fern to Prevent Sunburn (Sun Scorch)?
ð§ How to Water
Never let the mount dry out. Water or mist the tree-fern trunk or moss it grows on whenever the surface starts to lose its dampness, often every two or three days in dry weather. Use rainwater if your tap water is hard.
âïļ Lighting
Full shade, like the floor of a rainforest gully. Direct sun scorches and dries the thin fronds within hours.
ðŠī Ideal Soil
It does not grow in garden soil. Attach it to the fibrous trunk of a soft tree fern, a rotting log or a moss-covered slab so the rhizome sits on a damp, airy surface.
