Fertilising a Magnolia 'Susan'
To ensure the Magnolia 'Susan' thrives and displays its captivating floral display, it is important to provide it with the appropriate nutrients. Fertilizing should be carried out in early spring, just before the growing season begins. Utilize a slow-release, balanced fertilizer that can steadily nourish the plant over several months. This will support the development of lush foliage and the striking purple and pink blossoms characteristic of this variety.
It is critical to apply the fertilizer around the base of the shrub, taking care not to come into direct contact with the stem or leaves to prevent potential burn. Following the manufacturer's guidelines for the amount to use is crucial, as over-fertilization can be detrimental to the plant's health. A single application at the onset of spring is typically sufficient to sustain the Magnolia 'Susan' throughout its growing season.
