Plant Carex in well-drained soil, ideally enriched with organic matter, and choose a spot in full sun or light shade. Space plants to allow for their mature size and water regularly until established. Feed during the growing season and lift and divide crowded clumps in early spring to maintain vigour.

Most evergreen and semi-evergreen Carex don’t need cutting back in the the traditional sense. Instead, in late winter or early spring, just comb through the plant with your fingers or a rake to remove any dead or tatty foliage. If the plant looks untidy or has suffered winter damage, you can lightly trim back the worst leaves, but avoid hard pruning as it can spoil the natural shape and regrowth is quite slow.
