Although many types of ornamental grass are considered hardy, there are circumstances that make overwintering sensible. What are they and how does wintering work?
How do I properly overwinter my ornamental grass?
To overwinter ornamental grass successfully, protect freshly planted grasses that have been cut in the fall or cultivated in pots with brushwood, mulch or fleece in the root area and tie larger specimens together. Remove the winter protection in March so as not to hinder new growth.
Then wintering makes sense
Ornamental grasses can stay outside throughout the winter. But they should be protected outside if:
- they were only planted in autumn
- they are in a rough spot
- they were accidentally cut down in the fall
- They are kept in containers
- the temperatures suddenly drop very sharply (below -15 °C)
Overwintering measures for grasses
An ornamental grass outdoors can be covered with brushwood, a mulch layer of bark or compost, fleece or leaves in the root area. Larger specimens should also be tied together. Ornamental grasses in the pot are cut down, wrapped with a warming material in the planter area and placed on a wooden block (€8.00 on Amazon) or Styrofoam block.
Tip
Make sure that you remove the winter protection early in March. Otherwise the new growth will suffer!
