Fertilising a Carex oshimensis 'Evergold'
To ensure the lush, variegated foliage of Carex oshimensis 'Evergold' retains its vibrant colors throughout the seasons, a balanced approach to fertilization is key. Fertilize in early spring as new growth appears, using a complete, controlled-release fertilizer formulated for ornamental plants. This will provide the plant with essential nutrients, promoting robust health and enhancing its ornamental appeal.
It's important not to over-fertilize, as this species is not a heavy feeder and excessive nutrients can lead to unwanted growth at the expense of its natural form. A second, lighter application may be done in mid-summer to sustain its vitality, especially when planted in containers where nutrients may leach out more quickly. Always follow the manufacturer's instructions for application rates to maintain optimal plant health.
