Fertilising a Carex morrowii
To ensure the lush, evergreen foliage of Carex morrowii remains vibrant throughout the year, a balanced approach to fertilization is recommended. Apply a granular, slow-release fertilizer in early spring to support the plant's growth as it emerges from its winter dormancy. This feeding will provide the necessary nutrients to sustain the plant through its active growing period.
As this species thrives in well-drained soil, it is important to avoid over-fertilization, which can lead to nutrient runoff and potential harm to the plant. A second light application may be made in mid-summer to replenish nutrients if necessary, particularly if the plant is showing signs of growth slowing down or foliage color diminishing. Always follow the manufacturer's instructions for application rates, ensuring the health and vigor of the sedge.
