Growing Big Bluestem from seed is a relatively simple process. This native grass is known for its rapid growth and can reach impressive heights within just a few years. In the first year, the grass typically grows to a height of several feet. However, by the second or third year, it can easily reach a towering height of 8-10 feet.
When starting Big Bluestem from seed, it’s important to provide the right conditions for germination and growth. Here is a step-by-step guide to help you successfully grow Big Bluestem grass:
1. Seed Selection: Choose high-quality Big Bluestem seeds from a reputable supplier or nursery. Look for fresh seeds that are free from any signs of damage or disease.
2. Site Preparation: Select a sunny location in your garden or landscape for planting. Big Bluestem thrives in full sun and can tolerate a wide range of soil types, including clay, loam, and sandy soils. Ensure the area is well-draining to prevent waterlogging.
3. Soil Preparation: Before sowing the seeds, prepare the soil by removing any weeds, rocks, or debris. Loosen the soil using a garden fork or tiller to a depth of about 4-6 inches. This will help the roots penetrate easily and promote healthy growth.
4. Seed Sowing: Scatter the Big Bluestem seeds evenly over the prepared soil. You can sow the seeds by hand or use a seed spreader for more even distribution. Avoid sowing the seeds too deep; a depth of about 1/4 to 1/2 inch is ideal.
5. Watering: After sowing the seeds, gently water the area to ensure good soil-to-seed contact. Keep the soil consistently moist but not saturated. Regular watering is essential for successful germination and establishment.
6. Germination: Big Bluestem grass seeds typically germinate within 10-14 days under optimal conditions. However, germination may vary depending on factors such as soil temperature and moisture. Be patient and maintain proper moisture levels during this critical period.
7. Early Growth: In the first year, Big Bluestem grass will establish a strong root system and begin to grow shoots and leaves. The growth rate during this stage can vary, but it generally reaches a few feet in height.
8. Maintenance: Once the grass has established, it requires minimal maintenance. Water the grass during dry periods to keep the soil moist but avoid overwatering. Regularly check for pests or diseases and take appropriate measures if needed.
9. Mature Growth: As the Big Bluestem grass enters its second and third year, it will undergo rapid growth, reaching heights of 8-10 feet or even taller. The grass forms attractive clumps and produces stunning seed heads in late summer or fall, adding visual interest to your landscape.
10. Seasonal Care: In colder climates, Big Bluestem grass may die back during winter but will regrow from the roots in the following spring. Consider leaving the dried foliage standing over winter, as it can provide habitat for beneficial insects and add winter interest to your garden.
Growing Big Bluestem grass from seed is a rewarding experience. It is a hardy and resilient grass that can quickly establish itself and provide a stunning display in your garden or landscape. With proper care and maintenance, this native grass will continue to thrive and beautify your outdoor space for years to come.
