Caring for cherry sparkler fountain grass (Pennisetum setaceum ‘Cherry Sparkler’) requires a few important steps to ensure its health and vitality. This ornamental grass variety is known for its striking variegated foliage and graceful, fountain-like growth habit. While it thrives in grow zones 9-10, it can still be grown in zone 6 with some extra care.
1. Planting: Choose a location that receives full sun for at least six hours a day. Ensure the soil is well-drained to prevent waterlogging, as excessive moisture can lead to root rot. Before planting, amend the soil with organic matter like compost to improve its fertility and drainage.
2. Watering: Newly planted cherry sparkler fountain grass should be watered regularly to establish its root system. Water deeply, providing enough moisture to reach the roots. Once established, this grass is drought-tolerant and requires minimal watering. However, during prolonged dry periods, it’s beneficial to give it a deep watering once every two weeks.
3. Mulching: Apply a layer of organic mulch, such as wood chips or straw, around the base of the plant. Mulch helps retain moisture, suppresses weed growth, and moderates soil temperature. Keep the mulch a few inches away from the grass stems to prevent rot.
4. Fertilizing: Cherry sparkler fountain grass benefits from a balanced slow-release fertilizer in early spring or late winter before new growth appears. Follow the package instructions for application rates. Avoid over-fertilizing, as this can lead to excessive leaf growth and a less compact plant.
5. Pruning: In late winter or early spring, before new growth emerges, cut back the previous year’s growth to a height of 4-6 inches from the ground. This rejuvenation pruning helps maintain a neat appearance and encourages vigorous new growth. Wear gloves as the grass blades can be sharp.
6. Dividing: Over time, cherry sparkler fountain grass clumps may become overcrowded, leading to reduced vigor and less attractive growth. Every 2-3 years, consider dividing the clumps in early spring before new growth begins. Dig up the clump and separate it into smaller sections, ensuring each division has healthy roots and foliage. Replant the divisions in well-prepared soil, spaced apart to allow for future growth.
7. Pest and Disease Control: This grass is relatively resistant to pests and diseases. However, occasionally, aphids or grasshoppers may feed on the foliage. If necessary, treat the affected plants with insecticidal soap or use organic methods to deter pests. Regularly inspect the grass for any signs of disease, such as fungal infections, and promptly remove and dispose of affected plant material.
Personal Experience: I have had success growing cherry sparkler fountain grass in my garden in zone 6 by providing it with extra protection during the winter months. I mulch heavily around the base of the plant and cover it with a layer of burlap or a plant cover to protect it from frost. This method has helped the grass survive the colder temperatures and bounce back beautifully in spring.
Caring for cherry sparkler fountain grass involves proper planting, watering, mulching, fertilizing, pruning, dividing, and pest control. By following these guidelines, you can enjoy the vibrant and eye-catching display of this ornamental grass in your garden.
