Sweet Marjoram - Key Growing Information
DAYS TO GERMINATION: 7-14 days at 65–70°F (18–21°C).
SOWING: Transplant (recommended): Start seeds indoors 8-10 weeks before the last frost. Sow seeds on the surface of the growing medium, gently pressing them into the medium, as light is necessary for germination. Keep moist. Transplant into individual containers when seedlings are large enough to handle. Pinch out the growing tip of the plants to promote branching and higher yields. After the last frost, transplant out at 6-8" spacing in rows 18" apart.
Direct seed: Sow seeds after the last frost. Scatter the seeds, 2-3 seeds per inch, in a narrow band on top of the prepared soil and tamp gently into place, as seeds require light to germinate. Keep moist. Thin to stand 6-8" apart.
LIGHT PREFERENCE: Sun.
