Fertilising a Salvia officinalis 'Purpurascens'
To ensure the Salvia officinalis 'Purpurascens' thrives, a thoughtful approach to fertilization is necessary. It is best to fertilize this species at the beginning of the growing season, typically in early spring. A balanced, slow-release fertilizer is ideal, as it provides a steady supply of nutrients without the risk of overfeeding, which can promote excessive foliage at the expense of blooms.
Apply the fertilizer according to the manufacturer's instructions, taking care to distribute it evenly around the base of the plant, avoiding direct contact with the foliage to prevent burn. Given its moderate nutritional needs, additional feeding throughout the season is generally not required, especially if the plant is grown in fertile soil. Adequate fertilization will support the plant's vibrant foliage and striking summer blooms, contributing to its overall health and longevity.
