When used as a summer-to-winter screen, ornamental grasses can be a beautiful substitute for deciduous shrubs while still delivering the benefits of both. Plants that are generally tall-growing can flop and splay open, making the garden appear chaotic and exposing the heart of the plant—and anything you may have been using them to screen. Staking is often necessary to prevent grasses like maiden grass (Miscanthus sinensis) or tall sedge grass (Carex spissa) from collapsing over one another.

About Ornamental Grass

Ornamental grasses can be annual or perennial, short or tall, green, variegated, or even purple, depending on the genus they belong to. They can be grown in USDA plant hardiness zones 3 through 10 depending on the variety. Warm-season or cool-season ornamental grass can be found. In the fall, winter, and spring, cool-season grasses develop, bloom, and then go dormant for the rest of the year. Feather reed grasses (Calamagrostis spp.) and northern sea oats are examples of cool-season grasses (Chasmanthium latifolium). In the spring, warm-season grasses begin to develop, and they remain dormant during the winter months. Among them are Miscanthus sinensis (Maiden Grass) and Switchgrass (Switchgrass) (Panicum virgatum). For the most part, ornamental grasses require full sun and typical garden soil that drains well. In higher zones, cool-season grasses can tolerate afternoon shade.

When Staking is Necessary

You don’t need to fertilize your ornamental grass. Tall, spindly stems with a propensity to flop are the result of over-fertilizing a crop. When grown in the shade, sun-loving cultivars exhibit the same characteristics. Wind and rain can take a toll on tall ornamental grasses, especially in the latter stages of the growing season when the stems are dry and open in the core. This can also happen to older clumps. When the plants are still green but about to become dormant and brown, stake huge bunches.

Staking Techniques

Bamboo pegs are perfect for use with decorative grasses since they mix in so well with the plant. Put three to four stakes in the ground just inside the clump’s perimeter; the number depends on the size of the clump. There are at least two places where wire or twine is used to attach the stems of the plant: one third from the base of the plant, where the stems are the thickest, and just below where the stems naturally arch. To hide the connections, weave them in and out of the stems.

Alternatives to Staking

Plant kinds that have a strong upright habit and divide them every two to three years to limit the size of the clusters to avoid staking…………………………………… In climates with long growing seasons, ornamental grasses can also be clipped back in the middle of the season. Many ornamental grass stems are made up of many blades that branch off from the main stem, rather than a single straight blade. Reduce the height of the plant while maintaining a natural silhouette by removing the lowest leaves all around.

Causes of Ornamental Grasses Falling Over

Understanding why ornamental grass falls over makes it easier to prevent it from happening in your landscape. Most of the problems associated with flopping ornamental grass is because of gardeners taking too much care of the plants, not too little.

Once you know why ornamental grass falls over, it’s much easier to prevent it from happening again. It is more common for gardeners to take too much care of their decorative grasses than to take too little care of them.

As soon as the grass blades begin to grow in the spring, apply one application of 10-10-10 fertilizer to these plants. It’s best not to use any additional fertilizer this year. In addition to being overly large, an overgrown ornamental grass can topple down.

Divide these plants every three or four years to get the most out of them. Grass blades can get so heavy that the plant as a whole can sag and topple if it becomes too huge. Plant each new grass clump far enough away from its neighbors so that it does not shadow out the neighboring plants in the spring before any fresh shoots grow.

How to Fix Falling Ornamental Grass

As a result, how can you fix ornamental grass that has fallen? If your ornamental grass has been damaged and it has fallen over, you can use a quick repair to keep it upright until the stems are strong enough to support it again. In the middle of the grass, pound a stake or a piece of rebar into the earth. Garden twine that matches the grass should be wrapped around each clump approximately halfway up the stalks. Tie the rope loosely enough to allow the grass to flow freely, but tightly enough to keep the strands in one vertical cluster.

How To Keep Ornamental Grasses From Falling Over

In order to prevent ornamental grasses from falling over, you must become proficient at staking and division. Maintaining your decorative grasses is essential because it can be frustrating to see them teetering on the verge of collapse. A stake can be used to support the plants and maintain an attractive arrangement, rather than dividing the overgrown grasses.

If you don’t like to watch your ornamental grasses fall over, you don’t have to clip them or limit yourself to shorter varieties. Remember to observe the species’ growth patterns so that you can plan their placement over time. You may also choose to cultivate grasses in a greenhouse because it is easier to keep them indoors.

Tips For Successful Ornamental Grasses Parenting


First, you should stake your ornamental grasses to keep them from tipping over. Your plants’ growth habits should be your primary focus here, according to University of Vermont Extension. The ideal method for securing decorative grasses is to arrange them in the middle of the clump and secure them with twine at each of the points.

To keep the grasses upright, all you need to do is tie a piece of string around them. However, don’t forget to tie it such that it doesn’t obstruct the grass’s mobility. Before the grasses grow brown and lifeless, the ideal time to stake is also the best time.

Additionally, when staking decorative grasses, keep in mind that the stakes and twines should be able to mix in with the plants. Depending on the size of your clusters, you may need as little as two stakes, but this is not a rule of thumb. In the thickest stems and where they begin arching, plant them.


Dividing your ornamental grasses is another way to protect them from falling over. You can use this method to propagate your plants, but you can also use it to manage the size of your colonies after a few years. Every two years, you can perform this procedure as part of your maintenance of ornamental grasses.

It’s as simple as chopping the foliage down to six inches and removing the entire clump of plants. To get rid of the dead pieces, break it up into four sections with an ax. In order to avoid them drying out, quickly replant and water the divisions you’ve just removed.

It is possible to profit from midway pruning if your area has a long growing season. To avoid clumping, you can simply cut off the bottom blades of the plant’s foliage. However, some grasses may still benefit from being staked, so choose your strategy carefully.

There is a good chance that the grasses in your area will blow over in strong winds and rain. To protect the grasses from these adverse conditions, consider growing them in a greenhouse. The old clumps at the center of ornamental grasses can also die at the conclusion of the growth season, which affects the other upright grasses.

Since the grasses are still green, it is important to begin staking as soon as possible. Overfertilizing can cause spindly grasses that fall off readily, which is related to the dryness of the grasses. Only when the blades have begun to sprout in the spring should you fertilize.
