To grow Andropogon gerardii, also known as big bluestem or turkeyfoot grass, there are a few key steps to follow. This native grass is a great choice for borders, screens, or as a tall accent plant in your garden or landscaping. Here’s a detailed guide on how to grow Andropogon gerardii:
1. Planting: When selecting a location for planting big bluestem, choose an area that receives full sun. This grass thrives in sunny conditions and will not perform well in shaded areas. Ensure that the soil is well-draining, as big bluestem does not tolerate waterlogged conditions.
2. Soil Preparation: Before planting, prepare the soil by removing any weeds, rocks, or debris from the area. Loosen the soil with a garden fork or tiller to a depth of about 6-8 inches. This will help the roots of the grass to penetrate the soil easily.
3. Planting Method: Big bluestem can be planted as individual plants or in groups. If planting in groups, space the plants about 2-3 feet apart to allow them to grow and spread. Dig a hole slightly larger than the root ball of the plant and gently place the grass in the hole. Backfill the hole with soil, ensuring that the crown of the plant is level with the soil surface. Lightly tamp down the soil around the plant to remove any air pockets.
4. Watering: After planting, water the grass thoroughly to help settle the soil and provide moisture for root establishment. Keep the soil consistently moist but not waterlogged during the first few weeks after planting. Once established, big bluestem is very drought tolerant and can withstand periods of dry weather. However, during prolonged droughts, it may benefit from occasional watering.
5. Mulching: Applying a layer of organic mulch around the base of the plants can help conserve moisture, suppress weed growth, and regulate soil temperature. Use materials like wood chips, straw, or shredded bark, and spread the mulch evenly around the plants, keeping it a few inches away from the stems to prevent rot.
6. Maintenance: Big bluestem is a low-maintenance grass once established. It has a deep root system that can access water and nutrients from the soil, making it quite resilient. However, it’s a good idea to remove any dead or damaged foliage to keep the plant looking tidy. In early spring, you can also cut back the grass to a few inches above the ground to encourage new growth.
7. Division: Over time, big bluestem may spread and form clumps. To prevent overcrowding, you can divide the grass every few years in early spring or late fall. Dig up the clump and carefully separate it into smaller sections, ensuring that each division has a good portion of roots and shoots. Replant the divisions at the same depth as the original plant and water thoroughly.
Growing Andropogon gerardii, or big bluestem, involves planting in a sunny location with well-draining soil, providing adequate water during establishment, and maintaining the grass by removing dead foliage and dividing clumps as needed. Once established, this native grass is highly drought tolerant and can thrive in a variety of soil conditions. Enjoy the beauty and versatility of big bluestem in your garden or landscaping!
