Chinese Fountain Grass (Erianthus ravennae) is a striking ornamental grass known for its tall, graceful plumes and lush foliage. It adds texture and movement to gardens and landscapes, making it a popular choice among gardeners. Properly growing and caring for this grass ensures its vibrant appearance and healthy growth throughout the seasons.
Planting Chinese Fountain Grass
Choosing the right location is essential for healthy growth. Chinese Fountain Grass prefers full sun but can tolerate some light shade. It thrives in well-drained soil with moderate fertility. When planting, space the plants about 3 to 4 feet apart to accommodate their mature size and prevent overcrowding.
Growing Conditions
This grass is quite adaptable but performs best in USDA zones 5 through 9. It prefers moist, fertile soil but can tolerate drought once established. Mulching around the base helps retain soil moisture and suppress weeds. Regular watering during dry spells encourages vigorous growth and vibrant foliage.
Soil Preparation
Before planting, amend the soil with organic matter such as compost to improve fertility and drainage. Ensure the soil pH is slightly acidic to neutral (6.0 to 7.0). Proper preparation promotes healthy root development and lush foliage.
Care and Maintenance
Once established, Chinese Fountain Grass requires minimal maintenance. Regular watering, especially during hot, dry periods, is crucial. Fertilize in spring with a balanced, slow-release fertilizer to support growth. Cutting back the grass in late winter or early spring encourages new, vigorous growth and keeps the plant looking tidy.
Pruning
Cut back dead or damaged foliage in early spring before new growth begins. For a tidier appearance, prune the entire plant to about 6 inches above the ground. This promotes healthy, dense growth and enhances the plant’s overall appearance.
Dividing
Every 3 to 4 years, divide mature clumps in early spring or late fall to rejuvenate the plant and prevent overcrowding. Dig up the clump, separate it into smaller sections with roots attached, and replant immediately. This process encourages vigorous growth and maintains plant health.
Potential Problems
Chinese Fountain Grass is generally pest and disease resistant. However, it can be affected by rust, leaf spot, or fungal diseases in overly wet conditions. Ensure proper spacing and avoid overwatering to prevent these issues. Watch for pests like aphids or spider mites, which can be controlled with insecticidal soap or neem oil.
Winter Care
In colder zones, cut back the grass in late fall and apply a layer of mulch around the base to protect roots from freezing. In zones where the plant is not hardy, consider digging up the root ball and overwintering it indoors or in a protected area.
Enjoying Your Chinese Fountain Grass
Chinese Fountain Grass provides visual interest with its tall plumes and arching leaves. It is excellent as a focal point, in borders, or as part of a mixed perennial bed. Its feathery flower heads attract butterflies and add movement to the landscape. With proper care, this grass will thrive and beautify your garden year after year.
