Sowing Instructions

 

Sow seeds indoors from March to June, lightly pressing them into moist, well-drained compost. Keep in a warm, bright location for optimal germination. Once seedlings are large enough, transplant them outdoors after the last frost.

 

Alternatively, sow directly outdoors in late spring once the soil has warmed. Space plants 30-40 cm apart to allow for their upright growth and ensure proper air circulation.
