Fertilising a Skimmia japonica 'Rubella'
For optimal health and vigorous flowering, it is recommended to fertilize twice annually. Apply a balanced, slow-release fertilizer early in the spring to kickstart growth and once more in mid-summer to sustain robust development throughout the growing season. Since this species thrives in partial shade to full shade, it is crucial to avoid over-fertilization, which can lead to excessive growth at the expense of flowering. A light application, carefully worked into the soil around the base, ensuring not to disturb the root system, will suffice. As an evergreen with a consistent foliage display, maintaining a regular fertilization schedule will ensure the leaves retain their lustrous green hue year-round.
