Long-spike tridens

Long-spike tridens (Tridens strictus) is a perennial densely tufted grass that is native to the central and eastern United States. It grows in fields open ground ditches wastelands and roadsides and can tolerate both most and dry soils. Because of its bushy growth and distinctive purplish spike-like inflorescence that lasts from summer all the way to fall it is sometimes grown as an ornamental grass.

Growth Rate

At a moderate growth rate during spring, long-spike tridens substantiates tangible signs of accelerated biological activities including enhanced foliage density and an increase in overall size. Despite lower growth rates in other seasons, long-spike tridens maximizes its growth potential in spring light conditions, translating into a surge of energy for successful flowering and seed development.

Water: Long-spike tridens thrives in moderate climates with consistent moisture and prefers evenly moist soil. Water once weekly to mimic natural rainfall patterns, avoiding waterlogging. Consider local precipitation when cultivating long-spike tridens, as it typically grows outdoors in conditions similar to its native habitat.

Fertilize: To nourish long-spike tridens, use organic mulch or compost biannually in spring and fall. Spread around the root zone, avoiding the stem. Adjust application rates based on growth stage, and water thoroughly after fertilization to enhance absorption. This promotes healthy foliage and a sustainable ecosystem.

Pruning: Prune long-spike tridens in early spring to remove dead stems and leggy growth, promoting denser foliage and reducing disease risk. Use clean, sharp tools for pruning, which also encourages abundant flowering and enhances ornamental appeal. Consult reliable horticultural resources for further guidance.

Propagation: Long-spike tridens is a perennial grass that propagates effectively through division, creating genetically identical new plants. This involves splitting the root system and promptly replanting divisions with proper soil moisture. This method rejuvenates older clumps and allows for controlled spacing in garden designs.
