Fertilising a Rudbeckia fulgida 'Goldsturm'
To ensure the robustness and vibrancy of Rudbeckia fulgida 'Goldsturm', appropriate fertilization is key. This species thrives with a balanced approach to nutrition, benefitting from a moderate application of a general-purpose fertilizer early in the growing season. Apply this during the spring to kickstart the plant's growth, ensuring the nutrients are well-integrated with the soil to support the plant's development.
As the plant enters its flowering phase, a second application of fertilizer can be beneficial to sustain its prolonged blooming period from July through October. Care should be taken to distribute the fertilizer evenly around the base of the plant, avoiding direct contact with the foliage to prevent any potential nutrient burn. With proper fertilization, this cultivar will reward with a profusion of its characteristic yellow blooms and healthy green foliage throughout the growing season.
