How to Care for Blackhawks Big Bluestem
Before you buy Blackhawks Big Bluestem, make sure to read about the recommended care instructions to keep this plant healthy and thriving.
How do I plant Blackhawks Big Bluestem?
To plant Blackhawks Big Bluestem, start by choosing a location that offers full sun, as this warm-season grass thrives in bright light and well-drained soil. It is tolerant of poor soils and dry conditions, making it perfect for a variety of landscapes, including prairie gardens, borders, and slopes for erosion control. Begin by loosening the soil to a depth of about 6-8 inches, then dig a hole large enough to accommodate the plant’s root ball. Place the plant in the hole, ensuring the crown of the plant is level with the soil surface. Backfill with soil, gently firming it around the root ball, and water thoroughly to help the roots establish. For mass plantings, space Blackhawks Big Bluestem about 2 to 3 feet apart to allow the plants to spread naturally and fill the space. Once planted, water deeply to help settle the roots, and then continue to water regularly during the first growing season to encourage strong root development. Mulching around the base of the plant can help retain soil moisture and reduce competition from weeds. As this grass becomes established, it becomes drought-tolerant and requires minimal care, making it a low-maintenance option for sunny landscapes that need a dramatic vertical element with deep purple-black coloring.
How do I water Blackhawks Big Bluestem?
When watering Blackhawks Big Bluestem (Andropogon gerardii 'Blackhawks'), it's important to understand that this drought-tolerant native grass thrives in well-drained soil and prefers dry to moderately moist conditions. Once established, this ornamental grass requires minimal watering, making it an excellent low-maintenance choice for landscapes. During the first growing season, it's crucial to water the grass deeply and consistently to encourage root development. Water the plant approximately once a week, ensuring the soil stays moist but not soggy. Avoid overwatering, as soggy conditions can lead to root rot. As Blackhawks Big Bluestem matures, it becomes increasingly drought-tolerant and requires less frequent watering. After the first year, natural rainfall is usually sufficient to support the plant, though supplemental watering during prolonged dry spells can be beneficial. To maintain optimal health and growth, water deeply but infrequently, allowing the soil to dry out between watering sessions. This watering routine mimics the grass's native prairie environment, helping to preserve its rich burgundy-purple foliage and sturdy upright form.
How do I fertilize Blackhawks Big Bluestem Grass?
Fertilizing Blackhawks Big Bluestem Grass (Andropogon gerardii 'Blackhawks') is a simple process that enhances its vibrant burgundy color and encourages strong, healthy growth. This native grass thrives in poor to moderately fertile soils, so over-fertilizing can actually diminish its performance. For optimal results, apply a slow-release, balanced fertilizer (such as 10-10-10) in early spring, just as new growth begins to emerge. A light application is sufficient, as this grass is naturally adapted to thrive in less nutrient-rich soils. Be sure to avoid fertilizers high in nitrogen, as they can cause excessive leafy growth and reduce the plant's signature color and form. Once Blackhawks Big Bluestem is established, it typically requires little to no additional fertilization. However, if the plant is growing in particularly poor soil or you notice stunted growth, you can apply a small amount of organic compost or a low-nitrogen fertilizer in early summer to give it a gentle boost. Over-fertilization can lead to leggy growth and weaken the grass's resilience to drought. Remember, the beauty of Blackhawks Big Bluestem lies in its adaptability to various soil conditions, so minimal fertilization helps maintain its striking appearance and hardiness.
How do I Prune Blackhawks Big Bluestem?
Pruning Blackhawks Big Bluestem (Andropogon gerardii 'Blackhawks') is essential for maintaining its striking appearance and promoting healthy growth. The best time to prune this ornamental grass is in late winter or early spring, before new growth begins. Using sharp garden shears, cut back the dead foliage to about 4-6 inches above the ground. This helps clear away old growth, allowing the fresh, vibrant blades to emerge. Removing the previous season’s foliage also helps prevent any potential disease or pest issues that could arise from decaying plant matter. Throughout the growing season, Blackhawks Big Bluestem typically requires minimal pruning, as it maintains a strong, upright form naturally. However, if any stalks become damaged or unsightly, they can be selectively removed to maintain a clean appearance. Pruning this grass annually encourages denser growth and enhances its stunning burgundy-purple coloration. Avoid cutting back the grass during the fall, as the foliage provides winter interest and protection for wildlife, adding year-round appeal to your landscape.
