Setup, Compatibility & Care
To ensure your Helenium thrives, choose a planting site that receives full sun for the majority of the day. Dig a hole twice the width of your 9cm pot and mix in organic matter if your soil is particularly heavy. When planting, ensure the crown of the plant is level with the soil surface. Water consistently during the first few weeks after planting to help establish the root system. During the spring, you may apply a general-purpose fertilizer to encourage vigorous growth. In late autumn, once the flowers have faded and the foliage begins to die back, you can trim the stems down to near ground level to prepare the plant for winter dormancy.
