Planting and Caring for Carex ‘Evergold’

Carex ‘Evergold’ is relatively easy to grow. With proper planting and optimal care, you can establish a thriving colony of this sedge as an impactful garden element. Here is a guide to successfully cultivating Carex ‘Evergold’:

Site Selection

  • Carex ‘Evergold’ thrives in part sun to part shade. Provide at least 2-3 hours of sunlight to encourage growth.
  • It prefers consistently moist but well-draining soil. Avoid soggy or waterlogged sites.
  • Tolerates partial shade, allowing it to brighten up shaded gardens. Grows best in cooler climates.

Soil Preparation

  • Amend planting sites with compost or organic matter to improve drainage and nutrients.
  • Ideal pH range is 5.5-7.0. Acidic to neutral soil is preferable.
  • Eliminate weeds before planting as they may compete with young sedges.

Planting Depth & Spacing

  • Space plants 12-18 inches apart for a dense groundcover effect.
  • Dig holes twice as wide and deep as the container or root ball.
  • Plant crown should sit just above soil level. Do not bury too deeply.
  • Water thoroughly after planting and as needed until established.


  • Water 1-2 times per week during the first year, providing 1-1.5 inches of water each time.
  • After establishment, water deeply only once weekly unless rainfall is inadequate.
  • Avoid overwatering. Allow soil to partially dry out between waterings.


  • Apply a balanced organic fertilizer in early spring and midsummer.
  • Use a low or moderate nitrogen formula to prevent excessive growth.
  • Incorporate a thin layer of compost around plants each year.


  • Remove dead or damaged foliage as needed to maintain a tidy appearance.
  • Lightly trim in late winter if plant becomes overly large or dense.
  • Dividing is normally not required. But you can divide in early spring every 3-5 years to rejuvenate patches.

With proper site selection and care, Carex ‘Evergold’ will thrive with minimal upkeep. It’s far less demanding than many ornamental grasses once established.
