Propagation
Place spores on sterilised sphagnum moss, peat moss, bricks or terracotta pot base then cover with glass and keep moist. 4 to 6 weeks until prothalli appears. True fronds appear between 6-12 months after sowing.
Division during the growing period, cut the rhizomes in to lengths and plant apex upwards, apply bottom heat and keep moist.
Botanic information
Leaf: The fronds are bipinnate to tripinnate or sometimes quadripinnate with a polished reddish brown to black stipe. The variable bright to dark green membranous pinnules are cuneate with the outer margin lobed.
Flower: The fertile fronds produce 1-5 slightly concaved sori per pinnule that are arranged on the underside along the lobed margins and covered with a recurved marginal flap. They appear during summer.
Culture
When grown indoors Maiden Hair Ferns require a minimum night-time temperature of 10ºC (50ºF) and prefer high humidity around 60% which can be achieved with misting the surrounding air regularly. The plants do well in terrariums or placed in bathrooms in bright indirect light.
Re-pot only when necessary, as the plants prefer the roots to be crowded and water regularly during summer and reduce watering during winter. Do not allow the soil to become boggy.
