Fertilising a Melissa officinalis
For robust growth and the development of the aromatic qualities that Melissa officinalis is known for, it is important to provide appropriate nutrition. Fertilize this herbaceous perennial in early spring as new growth appears, using a balanced, slow-release fertilizer to support its vigorous bushy spreading growth habit. A second application can be beneficial during the midsummer to promote continued vitality and to prepare the plant for its flowering period in July through September.
Care should be taken not to over-fertilize, as this can lead to excessive leaf growth at the expense of the fragrance and potential flower production. Additionally, ensuring that the soil is well-drained will prevent waterlogged conditions that can negatively impact nutrient uptake. Regular fertilization will enhance the lush green foliage that persists from spring through autumn.
