Rosemary - Key Growing Information

Sprigs of a rosemary plant, grown from seed; like other Mediterranean herbs, rosemary prefers full sun and well-drained soil.
DAYS TO GERMINATION: 14-21 days at 65–70°F (18–21°C).

SOWING: Transplant (recommended): Start seeds in flats 10-12 weeks before the last frost. Sow seeds on the surface of the growing medium and gently press them into the medium. Cover the seeds lightly, as light is required for germination. Keep flats at 55-60°F (12-16°C) and keep the soil moist, but not soaked, until germination occurs. Transplant to individual containers or thin when plants have 4 true leaves. Transplant outdoors after the last frost in rows 18-36" apart. In-row spacing is 8-10" apart where it will be grown as an annual and 24-36" apart where it will be grown as a perennial. Rosemary may overwinter in colder climates if mulched or dug up and transferred to containers in a protected structure. If using primed seed, press seeds into the top of the growing medium. Germinate at 70°F (21°C). Treat the same as unprimed seed after germination is complete.
