There is a lot of misinformation out there about maidenhair ferns (Adiantum sp.) which paints them as being finicky and easy to kill when they are actually one of the easiest plants to care for. By looking at their natural habitat you can quite quickly start to see that there are really only two things that matter when it comes to growing this super lush fern. Light and water!
Maidenhair ferns can be found natively around Melbourne. After some research, and trial and error we have figured out how to grow the perfect maidenhair fern and are ready to share our secret with you.
Maidenhair ferns need to be in a very bright position. Look for a spot where there is enough natural (indirect) light that you don’t always have to use any electric lighting to be in the space comfortably. If the room is a bit darker try to keep the fern closer to window to maximize how much light it receives. A good way to tell if it’s a good position is that you will be able to see the sky from the plants perspective.
Cool direct sun either in the morning all year round, or direct afternoon sun in winter provides a huge boost to the growth speed without burning the plant. Our maidenhair fern receives direct morning sun everyday which is how it managed to grow to this size in only three months.
Maidenhair ferns are one of the few plants that you cannot over-water! They love to be consistently moist at all times. The easiest way to achieve this is to keep a deep tray under the pot they are in (self watering pots work great for this too.)
If the tray is empty, add water to it, if it’s full then your job here is done! In summer they can drink up quite a bit of water so be sure to keep the tray topped up at all times. In winter the tray can be allowed to empty for a short time without damaging the plant.
Avoid watering onto the leaves as they may snap. Watering directly onto the soil or just top up the tray.
