Fertilising a Digitalis grandiflora
For optimal growth and vibrant flowering, Digitalis grandiflora benefits from regular feeding. It is recommended to fertilize this species in early spring to kickstart its growth cycle. A balanced, slow-release fertilizer is ideal, as it provides a steady supply of nutrients throughout the growing season. Apply the fertilizer according to the package instructions, ensuring even distribution around the base of the plant, being careful to avoid direct contact with the foliage to prevent burn.
An additional light feeding may be beneficial after the first flush of blooms has faded, to encourage a robust second flowering. This species, with its stately spires and delicate blossoms, will reward such care with an impressive display from early summer into the fall.
