How to Grow
Start common spearmint seeds indoors between February and June in partial shade, as this perennial prefers a sheltered spot to establish. Ensure the soil is moist and well-drained to support healthy growth. Once established, spearmint thrives in containers, window boxes or garden beds where it can spread comfortably.
Sowing
Scatter the spearmint seeds thinly onto damp, well-drained soil and cover lightly. Place the container in a sunny spot and seal it to maintain warmth and humidity, which encourages germination during the sowing months of February to June.
Growing
Once seedlings appear, thin them out to prevent overcrowding and transplant into pots or garden beds, ideally using containers around 25 cm in size to allow room for spreading. This spacing helps maintain airflow and supports the plant’s vigorous growth habit during the growing season from May to September.
Plant care
Water spearmint regularly to keep the soil moist but not waterlogged, especially during warmer months. To encourage bushier growth and prevent legginess, pinch back the tips regularly. Cut back the plant after the growing season to maintain its shape and promote fresh growth the following year.
