The Japanese sedge looks like a small, prickly ball. Whether with white, variegated or just green foliage - requires little maintenance. But what about in winter? Does it tolerate frost or does it need winter protection?

Temperatures down to -20°C do not bother the Japanese sedge

This evergreen ornamental grass is hardy!

The Japanese sedge is an ornamental evergreen grass that also presents its decorative foliage in winter. The Japanese sedge does not necessarily need winter protection. It is considered to be very hardy. Their minimum temperature is around -20 °C.

Protect outdoor plants in exceptional cases

Is your Japanese sedge in a sunny location? Then it is advisable to protect them from the sun during the winter. Otherwise, if there is a frost, the leaves and stalks can be damaged. Good protection is:

  • leaves
  • brushwood
  • fir branches

Protect Japan sedges in the pot

A big exception are Japanese sedges in pot culture. If they stay outside over the winter, they are likely to freeze to death. The frost penetrates to the roots. The roots freeze and can no longer transport water to the leaves. As a result, the Japanese sedge dies due to drying out.

Therefore protect your Japanese sedge when it is in a pot! That is how it goes:

  • cut down in the fall
  • From October, surround the pot area with fleece or a jute sack (€10.99).
  • put the pot against the wall of the house
  • Place a piece of wood or a styrofoam plate (35.50€) under the pot
  • from April remove the winter protection
  • watering every now and then

Cut, divide and fertilize after the winter

When winter is over, there is a lot of maintenance to do. First of all, you should cut back your Japanese sedge if necessary (in the case of balding, severe frost damage, etc.). The cut is made just above the ground.

You can then dig up the ornamental grass and share it. The division stimulates growth and is ideal as a propagation method. Whether divided or not - a fertilizer application is also recommended. Compost and horn shavings are suitable as fertilizer. (32.93€) They are carefully worked into the soil.

tips

It is ideal if you plant the Japan sedge under deciduous trees. There the leaves fall down on the Japanese sedge in autumn and act as winter protection.
