We know mint for its culinary benefits but not everyone knows it's also one of the best herbs for attracting beneficial insects into the garden, such as hoverflies, lacewings and butterflies. 
Grow mint in moist but well-drained soil in full sun to partial shade. It’s best to grow mint in a pot as it can compete with neighbouring plants when planted in the ground. Harvest as and when you need to, allowing some stems to bear flowers for pollinators. Cut back to ground level in autumn and mulch with well-rotted compost annually.
