Fertilising a Aruncus dioicus
For optimal growth and development, Aruncus dioicus benefits from a regular feeding schedule. To foster a lush display of its distinctive white plumes, apply a balanced, slow-release fertilizer in early spring as new foliage begins to emerge. A second application can be made following the initial flowering period, typically in the middle of summer, to support vigorous growth and the potential for continued ornamental appeal into the autumn, when foliage may turn a striking yellow or orange.
It is best to avoid over-fertilizing, as this can lead to excessive foliage at the expense of flowering. Additionally, ensure that the fertilizer is evenly distributed around the base of the plant, avoiding direct contact with the stems to prevent any potential damage to the plant's structure.
