How to Grow

Start peppermint seeds indoors between February and June or sow directly outdoors after the last frost in a sunny or partially shaded spot. Peppermint thrives in moist, well-drained soil and is suitable for window boxes, balconies, containers, and garden beds.

  • Sowing

    Scatter the seeds thinly onto damp, well-drained soil and cover lightly. Place the container in a clear sealed environment in a sunny spot to encourage germination.

  • Growing

    Once seedlings appear, thin them out or pot on to allow adequate space for growth, ideally in containers around 25 cm in size. This ensures healthy development during the growing months from May to September.

  • Plant care

    Keep the soil consistently moist but not waterlogged to support the plant’s perennial nature. Regularly pinch back the tips to encourage bushier growth and harvest fresh peppermint leaves throughout the season.
