Depending on the species, the sedge can thrive in a wide variety of locations. But is it also undemanding when it comes to care? What is important if you want to enjoy it for a long time?

Normally, the sedge in the field does not need to be watered or fertilized

Do sedges need to be watered?

If sedges are properly established outdoors, they do not need to be watered except during dry periods. Only sedges that are kept in pots should be watered regularly. A lack of water can be recognized by the brown leaves of sedges.

Also, remember to water evergreen varieties. This is often forgotten and the plants do not die from the cold, but from dried out roots and plant parts. Keep the soil slightly moist by watering moderately with lime-free water.

Is fertilizer required?

When fertilizing it behaves as follows:

  • not absolutely necessary
  • low nutrient requirements
  • Outdoors: Fertilize with rotted compost in spring
  • in a pot: use liquid fertilizer or stick fertilizer or liquid manure
  • do not fertilize evergreen species in winter until every 8 weeks
  • ideal fertilizing times: spring and early summer

How are sedges cut?

Basically, it is not necessary to cut back sedges. Their old leaves and stems die off when they are no longer needed and can then be easily plucked out with your hands. It is better to wear gloves during this procedure, since the leaves of many sedge species are sharp-edged.

Are there pests that can be dangerous to them?

If the sedge is fertilized too much and too often, it becomes more susceptible to pests. Among others, aphids and spider mites can bother you. The aphids prefer to attack the stems. Spray the infested sedge with a strong jet of water or use a soapy solution to squirt.

When are sedges repotted?

When the leaves cover the entire surface of the soil in the pot, it's time to repot. Transplant the sedge in the spring and fill the plant pot with fresh potting soil! At the same time, now is a good time to cut.


Even if most other plants show their gratitude through a mulch cover in the form of bark. Sedges do not tolerate bark mulch and as a result quickly rot on the surface.
