Fertilising a Buphthalmum salicifolium
To ensure the vibrant yellow blooms of Buphthalmum salicifolium reach their full potential during the flowering months of July and August, a balanced approach to fertilization is key. It is best to apply a general-purpose fertilizer early in the growing season to support the plant's clump-forming growth habit and prepare it for a robust summer display. A second application can be beneficial as the first flowers begin to show.
Distribute a granular, slow-release fertilizer around the base of the plant, taking care not to disturb the roots or foliage. This provides a steady supply of nutrients, promoting healthy, green foliage and aiding the plant's overall vigor. Water thoroughly after applying fertilizer to help integrate the nutrients into the soil, especially as Buphthalmum salicifolium does not possess drought resistance and requires consistent moisture to thrive.
