Adiantum fragrans is commonly known as the Maiden hair fern, is one of the easiest Maiden Hair ferns to grown. This delicate and compact little fern has creeping rhizomes that produce clusters of spreading pinnate, lacy, light green fronds on shiny black stalks.
Maidenhair ferns are considered hardy ferns and able to be grown inside, thriving on moisture meaning they are well suited to bathroom situations.
In their natural forest environment, maidenhair ferns are primarily covered by a canopy of trees, receiving a bit of shade and partial sunlight. To successfully grow the fern indoors, try and mimic these conditions by finding a spot in your home that receives indirect sunlight only.
Maidenhair ferns prefer moist but well-draining potting soil. As mentioned, water is very important to this fern, so up your chances of creating the proper environment for it by incorporating moss or an organic matter like compost into the soil to help it to retain water.
Your best bet to ensure that your thirsty maidenhair fern thrives is to focus on giving it multiple water sources. Consistently moist soil is a great place to start—from there, be sure to water your fern regularly, either daily or every other day, never allowing the soil to dry out.
These ferns can be repotted annually or biannually, depending on the pot size and the plant's growth rate—they don't mind being a little crowded, so don't rush to repot them if you're unsure. Instead, wait for signs that your fern is outgrowing its home, like the roots filling up the pot.
