Plant Care & Growing Tips
Caring for your Black Fountain Grass First Knight is straightforward, ensuring this beautiful ornamental grass thrives in your garden. For optimal growth, plant it in a location that receives full sun, meaning at least six hours of direct sunlight per day. While it can tolerate part shade, its darkest foliage color and most vigorous growth will occur with ample sun exposure. This Pennisetum First Knight live plant prefers rich, well-drained soil. Good drainage is crucial to prevent root rot, so consider amending heavy clay soils with organic matter to improve aeration and drainage.
Water regularly, especially during dry spells and when the plant is establishing itself. Although it is drought-tolerant once mature, consistent moisture will encourage lush growth. Fertilize in spring with a balanced slow-release granular fertilizer to support healthy development. Pruning should be done in late winter or early spring, before new growth emerges. Cut the entire foliage clump back to the ground level to encourage fresh, vibrant new leaves. In USDA Zones colder than 7, where it is not reliably perennial, you can treat it as an annual or bring potted plants indoors to overwinter in a cool, bright location.
Monitor for common pests and diseases, though this grass is generally quite resilient. Ensure good air circulation around the plant to deter fungal issues. Proper spacing will also contribute to its overall health and vigor. By following these simple care guidelines, your dark foliage grass will provide years of stunning beauty and a unique aesthetic to your garden.
