One of the best things about ornamental grasses is that they are always interesting to look at in the garden, no matter what time of year it is.

Ornamental grasses are ideal for use in winter gardens, as they provide attractive form and texture. While some varieties might become dormant in the winter months, their presence in the garden can still be enjoyed.

From dried, fluffy seed heads to tall arching fronds that sparkle with frost in the winter sun. Ornamental grasses can provide magical colours and shapes within even the most baron landscape. And some grasses have evergreen foliage, providing some welcome colour to cheer up your beds and borders.

Caring for Ornamental Grasses in Winter

Ornamental grasses are generally low maintenance, but there are a few things you can do to ensure they stay healthy and look their best throughout the winter months.

Should I Trim Ornamental Grass in Winter?

It’s generally best not to trim ornamental grasses in the winter, as they can become damaged by frost. The grass is unlikely to regrow during this dormant phase, so you’ll also miss out on being able to enjoy the plant’s unique appearance at this time of year.

If you do want to cut back your grasses, wait until late spring when temperatures are warmer and any risk of frost has passed.

Mulching Ornamental Grass for Winter

A layer of mulch around the base of ornamental grasses can help to protect their roots during the winter months. Mulch also helps to retain moisture, which is especially important in dry spells, when plants may struggle to absorb enough water from the soil.

Keep Off the Grass!

Try to avoid walking on your grass, as this can damage delicate stems and leave them more susceptible to winter damage.


Are Ornamental Grasses Hardy in Cold Weather?

Most ornamental grasses are hardy (can tolerate the cold) and will stand up to the winter weather with minimal damage. Like most plants, you might find some varieties that will need a bit of extra care.

There are many ways to protect your plants in winter, such as mulching or covering plants with a protective material, such as gardening fleece.

Some grasses may struggle in areas that experience particularly cold winters, especially in exposed areas with harsh winds. If you know your hardiness zone, be sure to check the plant label or online information to make sure that the variety you choose is suitable for your local climate.
