Fertilising a Hosta tardiana 'Halcyon'
To ensure the vigorous growth and striking foliage coloration of Hosta tardiana 'Halcyon', a balanced fertilization regime is essential. It's recommended to apply a controlled-release fertilizer in the early spring to coincide with the onset of new growth. A second application can be made in mid-summer to sustain the plant's nutritional needs throughout its active growing season. The fertilizer should be well-balanced, with an equal ratio of nitrogen, phosphorus, and potassium to support the development of the robust, clump-forming habit and enhance the unique blue-grey tones of the foliage. Care should be taken to avoid over-fertilization, as this can lead to excessive leaf growth at the expense of flower production. Regular feeding with the appropriate amounts will contribute to the overall health and aesthetic appeal of this shade-loving perennial.
