Maidenhair Fern (Adiantum raddianum) History

Maidenhair Fern History Maidenhair fern history is quite interesting. Its genus name translates to “non wetting” and refers to the fronds’ ability to shed rainwater without becoming wet. In addition, the plant is the source of an aromatic, volatile oil commonly used as a shampoo, which is where its common name of maidenhair derived. Another name for this plant is the five-fingered fern due largely in part to its finger-like fronds, which are supported on dark brown to black stems. These black stems were once used as a dye in addition to being employed for the weaving of baskets. Native Americans also used maidenhair ferns as poultices for wounds to stop bleeding.

How to Grow and Care for Maidenhair Fern (Adiantum raddianum)

How to Grow Maidenhair Fern (Adiantum raddianum)

  • With Maidenhair Spores
You will know your plant is ready to produce spores when you see the sori (little brown dots on the underside of the leaf tips.) Cut off a few fronds with the sori and place them between two pieces of paper and leave it in a protected space for a week. The spores will drop onto the paper where you can then spread them over the soil in a small pot. Cover the top of the pot with plastic wrap to create a mini greenhouse. Make sure this is not in direct sun as it may get too hot.
Keep the soil moist and after a few weeks you will begin to see the gametophytes emerging. This is just one step in the process to achieving a new plant. After fertilisation of the gametophyte, the sporophytes aka ferns will begin to emerge.
  • With Maidenhair Division
Take an established plant and divide the root ball in half by gently ripping or cutting it. Don't worry if a few leaves die off once the division is complete. Place the new Maidenhair into pots and then continue so treat them as usual. A little seaweed extract added at this time can help the plants deal with any shock from being torn in half by you. Make sure the new pots you plant into aren't too large. Choose something bit bigger than the new root ball until the new plant is well adjusted to it's new life.

How to Care for Maidenhair Fern (Adiantum raddianum)

  • Light
Maidenhair ferns do best in bright indirect light, and are unable to tolerate much direct sunlight.
  • Soil
Maidenhair ferns are unique in that they have the ability to grow in extremely poor and fragile soils, as long as there is a constant source of shade and moisture.
  • Water
Maidenhair need to be kept moist, but you must also be careful not to overwater or underwater them! Too much water leads to root rot, and not enough water can lead to the plant drying out.
  • Temperature and Humidity
When it comes to maidenhair ferns and temperature, just keep in mind that Maidenhair like the same indoor temperatures that most humans do. As such, room temperatures of around 21 °C (70 °F) or more are preferred. You can provide humidity in any room with regular misting of the leaves.
  • Fertilizer
Maidenhair ferns need very little fertilizer and will grow steadily by just drawing nutrients from the soil. They are sensitive to the soluble salts found in most conventional fertilizers, so a light hand is needed when measuring and applying fertilizer.
