Fertilising a Viburnum carlesii
To ensure the health and vibrancy of this species, a balanced approach to fertilization is recommended. It is advisable to apply a general-purpose fertilizer before the onset of the growing season in early spring. This will supply the essential nutrients required for the forthcoming burst of growth and support the development of the dense clusters of fragrant white flowers. Additionally, incorporating organic compost into the soil can enhance nutrient content and improve soil structure.
With its moderate water needs, it is important not to over-fertilize, as this can lead to excessive foliage at the expense of flowering. A single application of fertilizer per year is typically sufficient to maintain the upright to bushy growth habit and promote the striking autumnal foliage transition to hues of red, as well as the production of the ornamental black fruit.
