Temperature Requirements
Andropogon verticilliflorus Steud. has a preference for warm temperatures. This plant can tolerate a wide range of temperatures, but in general, its ideal range is between 70°F and 90°F. This warm temperature range stimulates the growth and development of the plant's roots and foliage. If the temperature goes beyond this range, the plant may become stressed and growth may slow down, leading to less productive yields.
Soil Requirements
Andropogon verticilliflorus Steud. prefers well-draining soil that is rich in organic matter. This plant grows best in sandy, loamy, or clay soils with a pH range between 6.0 and 7.5. The ideal soil moisture content should be neither too dry nor too wet. Overwatering this plant can lead to root rot and other fungal diseases. Therefore, before planting, it is recommended to improve the soil quality by adding compost, manure or other organic matter to ensure the soil is well-aerated and nutrient-rich for optimal growth.
Cultivation Methods
Andropogon verticilliflorus Steud., also known as Whorled Andropogon or Whorled Bluestem, is a versatile grass species that is native to North America. It can be grown in a wide range of soil types, including clay, loam, sand, and gravel, and prefers slightly acidic to neutral soil.
The ideal location for planting Whorled Andropogon is in an area that receives full sun exposure, although it can also tolerate partial shade. Plant the grass seeds in the spring after the last chance of frost has passed.
When planting, space the seeds six inches apart and one-quarter inch deep for optimal growth. The seeds will germinate in two to three weeks and begin to grow rapidly in warm weather conditions.
Watering Needs
Whorled Andropogon is a drought-tolerant species that can survive extended periods without water. However, it is important not to completely neglect watering during dry spells, as consistent hydration promotes healthy growth and development.
When watering, aim to provide one inch of water per week, either through rainfall or manual watering. Avoid overwatering, as this can lead to root rot and other fungal diseases.
Fertilization
While Whorled Andropogon can grow in nutrient-poor soil, fertilization can help promote lush foliage and improved growth. Apply a balanced all-purpose fertilizer, such as a 10-10-10 or 20-20-20 formulation, at the beginning of the growing season and again in the late summer or early fall.
Avoid over-fertilizing, as this can cause excess nitrogen to build up in the soil and damage the grass.
Pruning
Whorled Andropogon is a low-maintenance grass species that requires minimal pruning or shearing. However, it can benefit from occasional trimming to maintain a healthy, attractive appearance.
Shear the grass back to a height of four to six inches in the spring before new growth appears. Avoid cutting back the grass too heavily, as this can stunt growth for the growing season.
Remove any dead, damaged, or diseased foliage as needed throughout the growing season to prevent the spread of disease or pests.
