When the leaves turn brown, the fern signals that it needs a bit of care. A cut might be appropriate here. How the fern is cut, whether a cut is necessary at all and when cutting makes sense is explained below.
When and how should you cut a fern?
Cutting ferns: In autumn or spring, cut most types of ferns to just above the ground to ensure he althy growth and winter protection. Evergreen ferns only require removal of old, brown leaves. To propagate cuttings, cut off the rhizome in spring.
Prune in autumn or spring
Most fern species should be cut down in the fall. It is sufficient to shorten the fronds to just above the ground. If you miss the cut in the fall, you have your next chance in the spring. But be careful: in spring there is a risk that the new fronds will be injured when cutting!
Leaves serve as natural winter protection
Some species of ferns are considered sensitive when it comes to frost. These include, for example, the Asian ferns. It would be better if they were only shortened by half. The lower area, which is left standing, catches and 'holds' the leaves that are to be placed over it as winter protection.
Alternatively, the brown fronds can be cut off in autumn and placed on the root area. In addition to winter protection, the fronds serve as a natural fertilizer. They decompose slowly and the formation of new fronds is stimulated and strengthened in spring.
Evergreen and wintergreen ferns
Evergreen fern species should not be cut back. Only old, brown leaves need to be cleaned out. Wintergreen ferns also look beautiful in winter. They need winter protection in the form of their fronds. Therefore they are only shortened in spring. This should best be done shortly before the new fronds sprout so that they are not injured.
Cutting ferns to obtain cuttings
Ferns can also be cut to obtain cuttings that are used for propagation. Such pruning should be done in spring. Use clean tools and gloves to protect against the poisonous parts of the plant.
Please note the following points when propagating cuttings:
- only possible for ferns with above-ground rhizomes
- Cut the rhizome 4 cm behind the growing point with a knife
- Plant rhizome in a pot with soil
- Keep soil moist
- Rooting duration: 4 to 6 weeks
- plant in a suitable location
Tips & Tricks
House ferns are cut in the same way as garden ferns.
