Sow indoors in moist seed compost in March-April. Keep the soil moist until the plants are established. Use a clear lid with air holes. Place in a bright, cool location after germination. Harden off and plant out once the risk of frost has passed. Can also be sown directly in the planting bed after the frost risk has passed. Regularly pick flowers for a longer blooming period.
