Peacock Fern Light Needs

Medium to bright indirect sunlight is ideal. Direct sun can burn the leaves though, so be careful.

How Often To Water

Keep them moist – check them twice a week and water if the top 30 or 40% is dry. Make sure it does not sit in water though.

Tip: when it comes to watering keep them moist but not soaking wet, tip out excess water after watering so they don’t get a soggy bottom!

Fertilizer

You do not need to feed this plant. They can be susceptible to fertilizer burn too. If you do feed, make sure it is a really well diluted feed.

Peacock Fern Soil

Use a normal potting compost. It does not want to be well draining, as they like to be moist.

When to Repot

It’s a good idea to repot them in spring to refresh their soil, even if they don’t need a bigger pot, keep them in the same one and refresh the soil.

Humidity

50% and above, they will thrive in a lot more too, making them a good plant for terrariums.

Tip: don’t let het humidity drop too low or the leaves can suffer, try to keep them above 50% humidity.

Temperature

18-25°C (64-77°F) is great for them in the day, and at night try to keep them above 10°C (50°F). They are fairly tolerant of most house hold temperatures.

How to Propagate Peacock Fern

You can propagate it fairly easily by stem cuttings or division. They root well in water so I would take stem cuttings, and let them grow in a jar of water. Then when they take well, repot them into soil. They are fairly easy to prop with cuttings. But if you have a big one then you can easily divide it to.
