Care: These ferns are native to a tropical environment, they prefer warm and humid conditions. Potted plants should get plenty of bright light, while outdoor Maidenhairs should be shielded from harsh sun and positioned in a shadier spot. Whether they are planted indoors or outdoors, they need to be kept moist and protected from drought. Foliage will quickly turn brown if it begins to dry out, be sure to maintain moisture but avoid waterlogging.
Propagation: Ferns can be propagated from spores that form on the underside of the fronds, by division, or by cuttings from rhizomes. Plant rhizomes in small well drained pots in a warm, moist, shady area.
