How to care for: Fern

Ferns date back to almost 400 million years ago, which means they now have evolved to many different types of species. Their green foliage precedes the time of dinosaurs, making them one of the oldest living things to exist. The plants are mainly found in rainforests. That's why they like humid environments, such as bathrooms and kitchens.

How do you take care of a Fern?

The best location for Ferns

Ferns likes to be positioned on locations with medium light to partial shade. Exposing a Fern to bright direct sunlight will turn the leaves to turn brown and burn them. Therefore, keep the Fern in a place where it receives indirect sunlight. If a Fern doesn't receive enough light, the leaves will turn yellow.

Watering the Fern

If a Fern gets too little water, the leaves will hang limp. Due to too little water, the stems are not full enough to hold the leaves high. It is therefore important to always keep the soil of a Fern slightly moist. You can check this to with your finger in the soil. Never let a Fern dry out. Not even in winter! It is best to water the Fern twice a week in summer, and once a week in winter. The most important thing? Give small amounts of water. A Fern can’t completely absorb big amounts of water within one week. This can cause the Fern to store the excess water in the roots. The plant can then suffer from root rot. You can easily recognise root rot by the yellow leaves with brown edges.


Repotting a Fern isn't necessary every year. The plant is a slow grower. We recommend repotting a Fern every 2 years. Repotting gives new nutrients and more room for root growth. The airier soil is also very good for the water flowing through. The best period to repot is spring.

Plant nutrition

The Fern uses a lot of energy from spring onwards to make new leaves. As a result, the plant needs extra nutrients. You can provide these nutrients by plant nutrition. We recommend giving plant nutrition once a month from spring until autumn. After autumn and in winter it is better not to give extra nutrients. In the winter, plant nutrition can actually be harmful for the Fern!

Air-purifying function

Ferns are strong air-purifying plants. This is mainly due to the large leaves. The large leaf surface gives the plant extra stomata. Ferns use these stomata to convert CO2 into oxygen during the day. And that is always good. For you and your home.

Is the Fern toxic?

Ferns, unfortunately, can be poisonous. This doesn’t apply to all species, so pay close attention to children and pets.

Diseases and peculiarities

An advantage of Ferns? They don’t get bugs and vermin too soon. If you can find vermin or bugs, use chemical pesticide for a healthy plant.
