Ripgut (Sporobolus michauxianus)

Ripgut

Also known as: Prairie cordgrass

Ripgut, also known as Prairie cord grass, is a North American perennial species of grass growing in wetland habitats. The growth is vigorous, both underground and above ground. The hard, hollow stems may reach 3 m in height, and rhizomes may spread as much yearly. Often, it forms dense stands that don't leave room for other species. Ripgut is harvested as a source of materials and can be used in soil stabilization projects.

Attributes of Ripgut

Growth Rate

During spring and summer, ripgut experiences a rapid growth rate, significantly boosting its leaf production and height. This quick pace contributes to a robust, thickened tussock and accelerates its flowering process. The rapid growth often leads to a remarkable transition, turning ripgut from a modest seed into an impressive grass display in a short season. Despite slower growth in other seasons, ripgut's development primarily revolves around its dynamic spring and summer growth phase.

Distribution of Ripgut

Distribution Map

Ripgut is a plant with a presence rooted primarily in North America, specifically the eastern regions. Over time, it has been introduced to parts of Europe, extending its range to encompass a selection of temperate zones. Its adaptability has allowed it to establish itself outside its native territory, although it is not widely reported as invasive.

Water: Originating from areas with periodic rainfall, ripgut efficiently utilizes moisture, showing moderate drought tolerance. It thrives with weekly watering, mimicking its native hydration cycle, and adjusts growth cycles to seasonal precipitation, ensuring resilience across various climate zones.

Fertilize: Fertilize ripgut quarterly with balanced nutrition fertilizers to promote growth, ensuring to avoid over-fertilization to prevent root burn. During winter, ripgut requires less fertilizer. Use granular slow-release types and water after application for optimal nutrient absorption.

Pruning: Ripgut thrives with early spring pruning to remove dead stems and improve air circulation. Thinning overcrowded areas enhances sunlight exposure. Regular pruning maintains shape, minimizes disease risk, and promotes healthy growth, ensuring a robust and attractive appearance throughout the growing season.

Propagation: Ripgut thrives in well-drained soils and propagates best through division. Split clumps with strong roots and shoots, replanting them promptly with adequate spacing. Consistent moisture and avoidance of deep shade foster healthy establishment for new plants.
