Fertilising a Miscanthus sinensis 'Ferner Osten'
To ensure robust growth and vibrant blooms, fertilizing is a crucial aspect of caring for Miscanthus sinensis 'Ferner Osten'. Commence feeding in early spring, just as the new growth begins to emerge, and consider a second application in mid-summer to support the plant's energy needs during its peak growing and flowering phase. A balanced, slow-release fertilizer is recommended to provide a steady supply of nutrients without overfeeding, which could lead to lush foliage at the expense of blooms.
Application should be done carefully, with the fertilizer distributed evenly around the base of the plant, avoiding direct contact with the foliage to prevent burn. This feeding routine will support the plant's striking autumnal foliage transition and the development of its distinctive brown and red inflorescences come late summer.
