A robust, grass-like perennial, slender mat rush thrives with minimal care, yet selective pruning enhances its appearance and health. Prune dead or damaged foliage anytime; however, for vigorous growth, cut back up to one-third in late spring before the growing season. Occasional thinning of dense clumps in summer or fall promotes air circulation, deterring pests and disease. Such maintenance ensures a tidy form and supports longevity, making these interventions both aesthetic and beneficial for the plant's overall vigor.
