For a long time, the fern seemed to be doing well. But for a few days now, transverse wrinkles have been appearing on your forehead when you look at him? The fronds have turned brown. What's behind it?

Too much sunlight can be the reason the fern turns brown

Deciduous ferns turn brown every year

If you have a deciduous fern and its leaves are turning brown in the fall, don't worry. Many ferns are deciduous and shed their fronds after turning brown. When it gets warmer again, new fronds will sprout. You can remove the old, brown fronds - if they bother you - as soon as they have dried up.

Too sunny location

Both indoor and outdoor ferns get brown leaves when exposed to direct sunlight. Very few fern species tolerate sunlight. Ferns should therefore preferably be planted in the shade or semi-shade.

Nutrient deficiency or wrong fertilizer

Another reason for brown fronds on the fern can be a lack of nutrients or, on the contrary, too much fertilization. Always use organic fertilizers for your fern. These plants are allergic to mineral fertilizers with too many salts. When it comes to fertilizing, the following also applies: less is more.

Dry soil or too dry room air

Another common reason why fern leaves turn brown is drought. Ferns need a lot of moisture. They should be watered regularly so that the soil is moist. However, make sure that no waterlogging forms. This leads to root rot and also to brown leaves.

In addition, ferns are pleased about the following measures:

  • use lime-free water for watering
  • Choose a location in the bathroom (high humidity)
  • Spray fronds daily with a hand sprayer
  • alternatively, wet the fronds with a damp cloth

Many house ferns will turn brown and eventually die if the humidity is too low. This is especially the case in the heated living room. Most ferns are absolutely unsuitable for such locations.

tips and tricks

If brown spots suddenly appear on the underside of the fronds, don't worry. These are the spore capsules of ferns. They are not an indication of care errors!
