Fertilising a Aster ageratoides 'Asran'
To ensure the vibrant late-season blooms of Aster ageratoides 'Asran', proper fertilization is key. A balanced, general-purpose fertilizer applied in early spring can support the lush, bushy growth habit and prepare the plant for its flowering months. Given the species' average water needs, it is essential to water the fertilizer in thoroughly to help distribute the nutrients to the roots.
Additionally, a second application of fertilizer may be beneficial in the late spring or early summer to sustain the plant's energy needs throughout its blooming period. Avoid over-fertilization, as this can lead to excessive foliage at the expense of flower production. Always follow the recommended rates on the fertilizer package to accommodate the nutritional requirements of this robust perennial.
