Core Care Logic

01

How Often to Water

Water when top inch of soil is dry

02

Finding the Right Light

A north-facing window or a spot far from any window. Your hand should cast a very faint, blurry shadow at most.

03

Choosing the Right Soil

This one needs airflow around the roots. Use a blend of bark chips, perlite, and charcoal. The mix should feel light and loose in your hands, not compact.

04

Temperature & Humidity

Prefers it on the warm side, 17–27°C. Keep away from cold windowsills in winter. Average home humidity (40–60%) works well. No extra effort needed.

05

What to Expect

This is a slow grower — it won't outgrow its spot anytime soon, so enjoy it as-is and mostly takes care of itself. Just remove the occasional yellow leaf.

What Makes It Special

“

Holly-like glossy leathery fronds with falcate (sickle-shaped) pinnate leaflets resembling holly (Ilex aquifolium); epithet falcatum means sickle-shaped and genus Cyrtomium from Greek kyrtos (arched) referring to arching frond habit.


auto_awesomeDistinctive non-lacy fern texture: stout short upright densely scaly rhizome producing coarse lustrous dark green fronds in a dense vase-shaped arching mound to 60–70 cm tall (1–2 ft) and 60–90 cm spread (2–3 ft).
auto_awesomeLithophytic perennial fern of the temperate biome: grows from crevices in coastal cliffs, stream banks, rocky slopes, waterfalls and masonry; can be grown mounted on driftwood, wooden boards, tree branches or rocks with sphagnum moss; thrives in moist stable areas in low indirect light to deep shade underneath trees.
