Fertilising a Coreopsis lanceolata 'Sterntaler'
To ensure a vibrant display of blooms from Coreopsis lanceolata 'Sterntaler', it is important to provide the plant with the appropriate nutrients. Fertilize in the early spring to kickstart growth, and then again at the onset of the flowering period in early summer. A balanced, slow-release fertilizer is ideal, allowing for a steady supply of nutrients throughout the growing season. Apply the fertilizer according to package instructions, taking care to avoid direct contact with the foliage to prevent any potential damage. Regular feeding will support this perennial's bushy and spreading growth habit, resulting in a lush and colorful impact in the garden. Additionally, as a deciduous species, a post-bloom fertilization can help prepare it for the next growing season.
