Fertilising a Phlomis russeliana
To ensure the robust growth and vibrant yellow blooms of Phlomis russeliana, a balanced approach to fertilization is recommended. This species benefits from a feeding in early spring as it emerges from dormancy and prepares for its flowering season. Utilize a general-purpose, slow-release fertilizer to provide a steady supply of nutrients throughout the growing months.
A second application of fertilizer may be given in mid-summer to support the plant's continued display of flowers and maintain its lush, silvery-green foliage. However, avoid over-fertilization, as this can lead to excessive foliage at the expense of flowers. Always follow the recommended rates on the fertilizer's packaging and apply it to the soil around the plant, taking care not to disturb the root system.
