It is best to apply fertilizers in the early spring, just before the growing season begins, to help the plant produce healthy foliage.
Cultivation of Andropogon hirtiflorus var. feensis
Andropogon hirtiflorus var. feensis is a native grass species commonly found in rocky and sandy prairies of the southeastern United States. It can be grown in a variety of settings, including gardens, landscapes, and natural areas.
When planting, make sure to select a location that receives full sun to partial shade. The soil should be well-draining and slightly acidic. Follow the planting instructions for the specific cultivar you have purchased, as planting depths and spacing may vary.
Watering Needs of Andropogon hirtiflorus var. feensis
Andropogon hirtiflorus var. feensis is drought-tolerant but will benefit from occasional watering during hot and dry spells. However, it is important to avoid overwatering as this can lead to root rot and other issues. A good guideline is to water deeply once a week, allowing the soil to dry out between watering sessions.
Fertilization of Andropogon hirtiflorus var. feensis
Andropogon hirtiflorus var. feensis does not typically require fertilization as it can obtain the necessary nutrients through its root system. However, if you choose to fertilize, opt for a slow-release organic fertilizer in the early spring before new growth appears.
Pruning of Andropogon hirtiflorus var. feensis
Andropogon hirtiflorus var. feensis does not require pruning for its overall health. However, if it becomes overgrown or ungainly, it can be trimmed back in the late winter or early spring.

Propagation of Andropogon hirtiflorus Kunth var. feensis
Seed Propagation: The most common method of propagating Andropogon hirtiflorus Kunth var. feensis is through seeds. The seeds can be obtained from mature seed heads that ripen in the late summer or early fall. To ensure that the seeds are viable, it is important to collect them before they are dispersed naturally. The seeds can be sown directly in the field or started indoors in trays.
Vegetative Propagation: Andropogon hirtiflorus Kunth var. feensis can also be propagated through vegetative means. This can be done through division of clumps or through stem cuttings. Division of clumps is the most common method of vegetative propagation and is done during the early spring or late fall when the plant is dormant. The clumps should be divided into smaller sections, each with its own root system and shoot buds.
Cultural Requirements for Propagation: Andropogon hirtiflorus Kunth var. feensis thrives in full sun and well-drained soils. It is a warm season grass that is well-suited for the southern United States. The plant requires regular watering during its establishment period, but once established it is relatively drought tolerant. Fertilizer is generally not necessary, but a light application of nitrogen-based fertilizer can be helpful to promote healthy growth.
