This fast-growing member of the marigold family can be started indoors or by direct sowing in the garden. Continue reading below for more tips on how to grow Mexican tarragon from seed.
Season & Zone
Season: Warm season
Exposure: Full sun to partial shade
Sow indoors 6-8 weeks before last frost, or direct sow 2 weeks after last frost. If starting indoors, just cover the seeds with vermiculite and provide a soil temperature of 21-25°C (70-75°F). Seeds should sprout in 4-14 days at that temperature.
The seedlings are somewhat prone to damping off. As a precaution, just cover the small seeds with vermiculite, water from below, and provide ventilation in the room. Space plants in the garden 30-45cm (12-18″) apart.
Pinch the growing tips to encourage branching. Edible flowers are borne in abundance once the summer heats up. This fast growing herb requires little care, but it does appreciate good drainage.
Pick leaves and flowers to steep as tea or as a substitute for traditional tarragon at any time during the summer. A yellow dye can be created from the flowers of this plant. The dried plant was traditionally burned to repel insects.
