Introduced to the United States in the late 19th century, fountain grass is now grown in many parts of the country, often thriving in various climates.
Propagation
Fountain grass can be grown from seed or propagated by division. Some cultivated varieties are sterile to prevent unwanted spread. Starting seeds indoors in early spring or dividing mature plants in late winter are common methods of propagation for this stunning plant.
Growing from Seed
- Sow seeds indoors in early spring or directly in the ground after the last frost.
- Water generously until germination occurs, usually within two to three weeks.
- Transplant seedlings outdoors gradually to acclimate them to the outdoor environment.
By Division
- Divide mature fountain grass plants in late winter or early spring for propagation.
- Cut back existing growth and carefully separate the outer edges of the root ball to create new plants.
- Replant the divided sections to establish new fountain grass specimens.
Transplanting
- Plant transplants in a sunny location with well-draining soil.
- Provide adequate spacing between plants for optimal growth.
- Water newly transplanted fountain grass deeply to establish healthy root systems.
How to Grow
To grow fountain grass successfully, plant it in a sunny location with well-draining, fertile soil. While full sun is ideal, this plant can tolerate partial shade as well. Regular watering and occasional fertilizing in the spring will help fountain grass thrive in your garden.
Growing Tips
- Plant in full sun for best results.
- Water weekly until established.
- Fertilize in the early spring as needed to promote healthy growth.
Pruning and Maintenance
Pruning fountain grass is essential to maintain its health and appearance. In late winter or early spring, trim back the plants to encourage new growth. Wear gloves to protect your hands from the sharp blades of the plant. To prevent self-seeding, remove seed heads before they shatter and spread. Container-grown specimens can be protected from cold temperatures to grow as perennials.

Managing Pests and Disease
While fountain grass is generally hardy and resilient, it can be susceptible to certain pests and diseases. Monitoring for aphids, mites, rust, and powdery mildew is crucial to maintaining healthy plants. Taking preventive measures such as proper watering, spacing, and plant care can help reduce the risk of infestations and diseases.
Common Pests and Diseases
- Aphids: Small insects that can cause yellowing and weakening of the foliage. Control with neem oil or natural predators.
- Mites: Tiny arachnids that suck juices from grass blades, causing yellowing. Avoid dry conditions to prevent infestations.
- Rust: Fungal disease causing yellow or red-orange blisters on leaves. Disposal of affected plant parts can prevent the spread of rust.
