The sword fern is a popular houseplant, especially for staircases, offices, living rooms and bathrooms. With its fresh green fronds, it is able to clean the air in the room. At the same time he looks beautiful. What care does he need?

Do you have to water the sword fern often?
Watering is probably the highest priority when owning the sword fern. This tropical plant needs an evenly moist soil. If the root ball is too dry, this will be demonstrated by the fronds on the surface within a short time. They dry out from the tips.
This is to be considered when watering:
- high need for moisture
- Dry the soil, but don't let it dry out
- Avoid getting wet, pour off excess water
- Drought can lead to the shedding of entire fronds
- additionally spray fronds to increase humidity
- use low-lime water for watering (stale water)
- like to take a shower from time to time
Does this houseplant need fertilizer?
The sword fern should be fertilized regularly to stay fit. Nutrient deficiencies slow growth. Too much fertilizer can result in yellow fronds. Find the healthy middle ground!
This is how it works: Fertilize once a week between March and October. In winter, fertilize sparingly or not at all every 4 weeks. Liquid fertilizer or slow-release fertilizer is used for fertilizing. It is ideal to use semi-concentrated green plant fertilizer.
How often does it need to be repotted?
Spring is the best time to repot:
- when the roots fill the pot, repot
- Young plants: repot every year
- older plants: repot every 3 years
- do not fertilize after repotting
- water well
Does the sword fern resent a pruning?
It is not necessary to prune the sword fern. Only if the fronds are too long for you, dried up, yellowed or diseased should they be trimmed. In general, the sword fern tolerates cutting well.
What damage to health can occur?
If the site conditions are not right or care is neglected, pests have an easy time of it. Spider mites, aphids and scale insects in particular then appear on the sword fern. Diseases can cause root rot if the substrate is too wet.
