Fertilising a Mentha × piperita
To ensure the vigorous growth and the aromatic potency of Mentha × piperita, it is essential to provide it with adequate nutrients. Fertilize this herbaceous perennial in the early spring and again in midsummer to encourage lush foliage and abundant flowering. A balanced, all-purpose fertilizer will suffice, but one that's slightly higher in nitrogen is beneficial, given the plant's propensity for leaf production.
Apply the fertilizer according to the package instructions, being cautious not to overfeed, which can lead to excessive foliage growth at the expense of the flavorful oils. Water the plant well after applying fertilizer to help distribute the nutrients into the soil. With proper fertilization, Mentha × piperita will reward you with a bountiful growth of fragrant leaves perfect for culinary uses and herbal preparations.
