In this guide, we’ll walk you through the basic steps of growing and caring for Shenandoah Switch Grass, as well as discuss possible problems and how to solve them.

What Is Shenandoah Switch Grass?

Shenandoah Switch Grass, scientifically known as Panicum virgatum ‘Shenandoah,’ is a captivating ornamental grass native to North America but is primarily found in the eastern and central regions of the United States.

This grass, commonly known as switch grass, has become popular in landscaping for its vibrant color and ornamental appeal.

This perennial grass grows in clumps, reaching a height of 3 to 4 feet (90-120 cm) with a spread of up to 3 feet (90 cm).

Its most striking feature is its stunning wine-red foliage, which adds a touch of elegance to any landscape.

Its graceful form and vibrant color make it an excellent choice for borders, meadows, or as a standalone specimen.

When the wind blows, the erect stems and airy plumes create a mesmerizing effect.

But beyond its aesthetic appeal, switch grass provides habitat and food for birds and other wildlife, making it a valuable component of eco-friendly gardens.

It can also help in erosion control, as its extensive root system helps stabilize the soil.

Here’s how to plant Shenandoah Switch Grass.

Method #1: Seeds

Shenandoah Switch Grass can be grown from seeds purchased from a reputable supplier or collected from existing plants.

Then sow the seeds in soil prepared in spring or fall and keep the soil consistently moist until the seeds germinate, which usually takes a few weeks.

Once the seedlings begin to grow, thin them out to maintain proper spacing.

Method #2: Division

If you already have an existing Shenandoah Switch Grass plant, you can propagate it through division in early spring before new growth begins.

Dig up the clump of grass and carefully separate the plant into smaller sections, ensuring each division has enough roots and shoots.

Replant the divisions in well-prepared soil, making sure to space them appropriately.

Method #3: Nursery Plants

You can also grow Shenandoah Switch Grass by purchasing nursery-grown plants.

You can purchase your local nursery or garden center to find healthy and well-established Shenandoah Switch Grass plants.

Then gently place the plant in a hole in your garden slightly larger than its root ball.

Fill it with soil and resume regular care as recommended by the nursery.

Here’s how to care for Shenandoah Switch Grass.


During the initial growing season, you should regularly water your Switchgrass to help the plants establish strong root systems.

Although they are generally drought-tolerant once established, water deeply but irregularly, allowing the soil to dry out between waterings.

Do not overwater these plants, as excess water can cause root rot.


Shenandoah Switch Grass thrives in full sun to partial shade with at least six hours of direct sunlight daily to maintain its vibrant foliage color and overall health.

It can tolerate some shade, but providing it with enough sunlight will promote optimal growth and color development.


Shenandoah Switch Grass can thrive in a range of temperatures.

It can withstand hot summers and is also cold and hardy, making it suitable for regions with harsh winters.

It is hardy in USDA hardiness zones 4 to 9, adding winter interest to any landscape.


Shenandoah Switch Grass generally doesn’t require frequent fertilization, especially if grown in nutrient-rich soil.

However, you can apply a slow-release, balanced fertilizer in early spring to boost nutrients.

Follow the instructions on the label for application rates and methods.


You can apply a layer of organic mulch around the base of the plants to help conserve moisture, suppress weed growth, and regulate soil temperature.

Use a mulch such as shredded bark or compost and spread it to a depth of 2 to 3 inches (5-7.5 cm).


Shenandoah Switch Grass maintains an attractive form on its own, so pruning is generally not necessary.

However, you can trim the plants to a few inches above the ground in early spring before new growth emerges to remove any dead or damaged foliage from the previous season and encourage new growth.

Possible Problems of Shenandoah Switch Grass

Here are some problems that may arise when growing Shenandoah Switch Grass.

Fungal Diseases

Shenandoah Switch Grass can be susceptible to fungal diseases like rust, leaf spot, or powdery mildew.

These diseases often occur in humid conditions or when plants are overcrowded and manifest as discolored or spotted foliage.

To prevent fungal diseases, ensure proper air circulation around the plants, avoid overhead watering, and promptly remove and properly dispose of any infected plant material.

In severe cases, you may need to apply fungicides.


Although Shenandoah Switch Grass is resistant to many pests, aphids and grasshoppers may occasionally feed on the foliage, causing damage.

Monitoring your plants regularly and taking appropriate measures to control pest populations if necessary is advisable.

Insecticidal soaps, neem oil, horticultural oils, or natural predators can help manage these pest infestations in a more environmentally friendly manner.

In Severe Cases

If these problems worsen, consult local gardening resources or seek expert advice.


These grasses can occasionally flop or bend their stems if grown in overly fertile soil or partially shaded conditions.

If this occurs, you can provide support, such as using stakes or surrounding the plants with other supportive plants.


Whether used as a focal point, border, or meadow planting, Shenandoah Switch Grass adds visual interest and texture to any garden or landscape.

And the fact that it is easy to grow and care for makes it all the more delightful.
