Fertilising a Sorbaria sorbifolia 'Sem'
To ensure the vigorous and lush growth of Sorbaria sorbifolia 'Sem', proper fertilization is key. It is recommended to fertilize this shrub early in the growing season, ideally in the spring, to support the development of its stunning foliage and robust stems. A balanced, slow-release fertilizer applied once in the spring will provide the necessary nutrients for the entire growing season.
When applying fertilizer, distribute it evenly around the base of the plant, avoiding direct contact with the stems to prevent any potential damage. Water the area thoroughly after fertilizing to help distribute the nutrients into the soil. This feeding strategy will encourage the shrub's upright to bushy growth habit, enhance the beauty of its seasonal foliage colors, and support the production of its charming white flowers during the summer months.
