Maidenhair ferns will perform best when in an area which maintains a temperature of 70˚F (21˚C). If possible, temperatures below 60˚F (16˚C) should be avoided. Being kept outside of this temperate range for prolonged periods of time can lead to poor plant health.

Soil Requirements

Maidenhair ferns require a moist but well draining soil.
