  • Plant in spring or fall when temperatures are moderate
  • Space plants 12-18 inches apart for eventual coverage
  • Water regularly the first season to establish strong roots
  • Once established, this sedge is remarkably low-maintenance
  • Divide clumps every 3-4 years if you want to propagate or control spread
  • Cut back old foliage in late winter before new growth emerges

Wildlife and Ecosystem Benefits

Beyond its garden appeal, owlfruit sedge provides valuable habitat for wildlife. The dense clumps offer shelter for small animals and birds, while the seed heads provide food for various bird species. The plant also supports insects that rely on native grasses for habitat and nesting materials, making it a valuable addition to pollinator-friendly landscapes.
