Cutting Back Zebra Grass: What You Need to Know

Cutting back zebra grass can be a daunting task, but with the right approach, you can keep your ornamental grasses looking their best. Zebra grass, also known as Miscanthus sinensis 'Zebrinus', is a popular ornamental grass that can grow quite tall.

It's essential to cut back zebra grass in late winter or early spring, before new growth begins. This allows the plant to recharge and prepare for the growing season ahead. Cutting back zebra grass too early can lead to new growth before the plant has a chance to recover.

Cutting back zebra grass can be done by hand or with pruning shears. It's recommended to cut back the dead foliage to about 3-4 inches from the ground. This will help promote new growth and prevent the plant from becoming leggy.

Before you start cutting back your zebra grass, it's essential to understand that there are two types of ornamental grasses: cool season and warm season.

You can trim ornamental grass in late fall or very early spring before new growth emerges.

For both types of grass, we recommend waiting until early spring for the best results.

Trimming in late fall can cause the crown of the plant to be exposed to winter weather, potentially damaging it.

Waiting until spring also allows the plants to provide winter interest, making them a valuable addition to your landscape during the colder months.

When working with zebra grass, it's essential to wear thick leather gloves to protect yourself from sharp edges.

You'll need a good pair of gloves, as some ornamental grasses can have very sharp edges.

For smaller zebra grasses, a pair of pruning shears will probably be sufficient.

Trim about 2/3 of the plant for cool-season grasses, which is a good rule of thumb.

Tying the grass in a bundle before trimming makes clean up a snap, and it's a great idea for most ornamental grasses.

For short grasses, tying them together might not be possible, but it's still worth a try.

If you have a large, established clump of zebra grass, you may need to use a weed eater, electric or gas powered hedge trimmers, or even a chain saw.

Tie the tops together for easier clean up, and then toss the bundles into your compost pile.

After cutting back your zebra grass, it's time to tidy up the area. Collect the cuttings in a wheelbarrow or on a tarp to transfer to the compost pile if you have one.

You can also use biodegradable yard waste bags for disposal if you don't have a compost pile. This helps keep the area clean and prevents the spread of disease.

Cutting back zebra grass can be a bit tricky, but there are some special considerations to keep in mind.

Zebra grass can be quite invasive, so it's essential to wear protective clothing and gloves when cutting it back to avoid skin irritation.

Make sure to cut the grass in sections, working from the outside in, to prevent the clippings from spreading to other areas of the garden.

Cutting back zebra grass can be a bit messy, so it's a good idea to have a tarp or drop cloth on hand to catch the clippings.

Suggestion: Cutting Grass and Leaving Clippings

Not cutting your grass in the spring doesn't affect its overall health. Actually, the new green leaf blades will mask last year's foliage, making it nearly invisible.

Leaving ornamental grasses standing over the winter protects the growing points of the plant from extremely cold temperatures. This is especially beneficial for the plant's survival.

Removing old growth can help get rid of debris and mimic the natural process of fires that created the prairies where many ornamental grasses developed. This can be a good thing, especially if you want to encourage new growth.

Cutting or burning your ornamental grasses in the spring can have a benefit - it helps spring growth begin earlier. This is because removing old foliage allows the crown to warm up faster, starting growth up to 3 weeks earlier.

If it's too late in the season to prune your ornamental grasses, consider removing the most offending seed heads with scissors.

Cutting them back now would just prolong the ugly duckling phase.

Cutting the grass late in the season will trigger new growth from the base of the plant.

After a few weeks of regrowth, it should look good as new.

Cutting ornamental grasses back in the summer can sometimes result in shorter growth with rounded leaf tips.

Divide ornamental grasses every few years, especially when the crown expands outward and leaves a dead center.

When cutting back zebra grass, it's essential to know the type of grass you're dealing with. Most flowering grasses, including Calamagrostis, Miscanthus, Panicum, and Pennisetum, are deciduous, meaning they die back in the winter.

If your zebra grass is indeed deciduous, you can cut all the old growth back to the base at the end of winter. Simply use secateurs to remove each of last year's stems individually, being careful not to cut off the new shoots that are emerging at the base.

Evergreen grasses, on the other hand, don't need regular annual care if they're looking neat and healthy. You can simply comb or rake off any old, tired, or dead leaves and flowers in spring.

Some grasses, like pampas grass (Cortaderia) and bamboo-like Arundo donax, are semi-evergreen or evergreen in the UK climate. These should be cut back hard each spring to encourage new foliage.

Here's a list of some evergreen and semi-evergreen grasses that require minimal maintenance:

Remember, if your zebra grass is evergreen, it's best to cut back the old growth to make way for the new.
