Fertilising a Veronica spicata 'Inspire Blue'
For optimal growth and a profusion of vibrant blue blooms, it is essential to fertilize the Veronica spicata 'Inspire Blue' adequately. Fertilization should occur in early spring, as new growth appears, and again in midsummer to support its prolonged flowering period, which stretches from June to September. Apply a balanced, slow-release fertilizer formulated for flowering perennials, following the manufacturer's instructions to avoid over-fertilization, which can lead to excessive foliage at the expense of flowers.
Well-drained soil is preferred for this species, and ensuring proper nutrition helps maintain its clump-forming and ascending growth habit, as well as the lush green foliage that beautifully offsets the blue flowers. Regular fertilization not only encourages a more robust display of blooms but also supports the overall health of the plant.
