Seasonal Appeal: The plant’s blooms turn a lovely golden-brown as they age, providing winter interest. Even in winter, its structure adds texture to the garden.
Types of Fountain Grass
There are a few different varieties of fountain grass, each with its own unique features:
-
Pennisetum alopecuroides ‘Hameln’: A popular variety that grows to about 2 to 3 feet in height, with fine, graceful plumes.
-
Pennisetum alopecuroides ‘Little Bunny’: A compact variety that reaches about 18 inches, ideal for smaller spaces.
-
Pennisetum ‘Karley Rose’: Known for its pink-tinged flowers and compact growth habit.
Planting Fountain Grass
Planting fountain grass is straightforward, but it’s important to follow the right steps to ensure its success.
Best Time to Plant Fountain Grass
The best time to plant fountain grass is in the spring, once the last frost has passed. This timing gives the plant a full growing season to establish its roots before the colder months arrive. Fountain grass can also be planted in the fall, though this is riskier in areas with harsh winters.
Choosing the Right Location
Fountain grass loves the sun! Ideally, plant it in a spot that gets at least 6 hours of sunlight a day. It can tolerate some shade, but its growth and blooming may be less vibrant in shadier spots. The plant prefers well-drained soil, so be sure to avoid areas with poor drainage or standing water.
When selecting the right spot, consider the height of fountain grass and how it will fit into your landscape. It’s great for creating borders, adding texture to flower beds, or even as a striking focal point in your garden.
Soil Preparation
Fountain grass prefers slightly acidic to neutral soil. It’s important to ensure the soil drains well to prevent root rot. If your soil is clay-heavy, improve drainage by adding compost or organic matter. A light, loamy soil with good texture is ideal for fountain grass to thrive.

How to Plant Fountain Grass
-
Dig a hole that is twice as wide and as deep as the root ball of your fountain grass plant.
-
Place the plant in the hole, ensuring that the top of the root ball is level with the surrounding soil.
-
Fill the hole with soil, gently firming it around the roots. Make sure the plant is upright and centered.
-
Water thoroughly to settle the soil and remove any air pockets, ensuring the roots have good contact with the soil.
Container Planting Tips
Fountain grass can be grown in containers, making it a perfect choice for patios and small gardens. Use a large pot with good drainage and well-draining potting mix. Fountain grass enjoys plenty of sunlight, so ensure your container gets enough light, especially during the growing season. Water the plant regularly to keep the soil moist, but not soggy.
How to Care for Fountain Grass
Once planted, fountain grass requires minimal maintenance, but a few key care tips will ensure it thrives year after year.
Watering
Fountain grass is drought-tolerant once established, but it will perform best with consistent watering during dry spells. Water the plant deeply to encourage deep root growth. However, be careful not to overwater, as this can lead to root rot. Let the soil dry out slightly between waterings.
Fertilizing
Fountain grass doesn’t need much fertilizer. A light feeding of balanced, slow-release fertilizer in the spring will help promote strong growth. Avoid over-fertilizing, as this can cause the plant to become leggy and reduce flower production.
Pruning
Pruning fountain grass is essential to keep it looking its best and promote healthy growth. The best time to prune is in late winter or early spring, before the new shoots begin to appear. Cut the plant back to about 2 to 4 inches above the ground. This will help rejuvenate the plant, allowing new, fresh growth to emerge.
Seasonal Care Tips
-
Spring: Prune back old growth, apply fertilizer, and water well as the growing season begins.
-
Summer: Keep the plant well-watered, especially during hot, dry spells. Fountain grass thrives in full sun, so ensure it gets plenty of light.
-
Fall: Trim back spent flowers and clean up any fallen leaves to keep the plant tidy.
-
Winter: Fountain grass is hardy, but if you live in an area with cold winters, consider adding a light mulch around the base of the plant to protect the roots.
How to Overwinter Fountain Grass
Fountain grass is generally hardy in USDA zones 6 to 9 and can survive the winter with minimal preparation. In areas with harsher winters, such as zone 5, it’s recommended to plant fountain grass in a protected spot and apply a layer of mulch around the base to insulate the roots from freeze-thaw cycles. If you experience a particularly severe winter, some of the plant’s crown may die back, but you can simply trim away the dead portions in the spring. In regions with milder winters, fountain grass will often remain evergreen and continue to provide year-round beauty.
How to Propagate Fountain Grass
Fountain grass can be propagated through division, making it easy to grow more plants.
-
In early spring, dig up an established clump of fountain grass.
-
Use a sharp knife or spade to divide the plant into smaller sections, making sure each division has healthy roots.
-
Replant the divisions in well-prepared soil or containers.
Troubleshooting Common Issues
Fountain grass is relatively low-maintenance, but a few common issues can arise:
-
Yellowing Leaves: Yellowing leaves can be a sign of overwatering or poor drainage. Check that your soil is well-draining, and adjust your watering schedule if needed.
-
Pests: Fountain grass is generally pest-resistant, but aphids or spider mites may occasionally appear. Use insecticidal soap or neem oil to control them.
-
Diseases: Powdery mildew can affect fountain grass, especially in humid climates. Avoid overhead watering and make sure the plant has good air circulation to reduce the risk.
