With delicate ferny foliage, Maidenhair ferns are a large group of ferns (Adiantum) with over 150 species. They are a popular fern for growing indoors although with proper care and in the right conditions many varieties can be grown outdoors as well.
Although originally from tropical and temperate climates, the secret to growing Maidenhair Ferns are constant conditions, and a little humidity.
They are a fern that likes to settle, and be left alone, not moved around. Maidenhair ferns species readily available for sale in Australia

Maidenhair fern Fertilizer and Care
We use a liquid seaweed based fertilizer with all Maidenhair ferns, the occasional application of some worm castings or liquid worm waste, seems to work well. A saucer of water placed beneath the pot will provide the humidity that these ferns like, but remember to sit the pot above the water on some stones or ‘pot feet’.
Pests and Problems
If allowed to dry out your fern may appear dead, try a good soaking (overnight) in a weak liquid fertilizer solution and you may be surprised as it comes back to life. Aphids can be controlled with a pyrethrum spray.
