Growing at a glance…

Sow seeds indoors or under cover in warm conditions 4-6 weeks prior to the last frost in individual pots or trays (around March-April). Sprinkle seeds over trays and cover with 1/4 inch fine soil. Ensure the soil stays partly moist and warm during germination - preferably somewhere that gets plenty of sunlight like a windowsill. Can be sown directly outdoors after danger of frost has passed, usually from July to October. Thin to 12 inches apart when plants are 5-10cm tall. Gradually move plants grown inside outdoors after all danger of frost has passed.
