Sweet Marjoram - Key Growing Information

Sweet marjoram, grown from seed and transplanted into the field, prefers light, well-drained soil and full sun.

DAYS TO GERMINATION:

Seedlings appear in 7–14 days at 65–70°F (18–21°C).

SOWING:

Transplants are recommended: start indoors 8–10 weeks ahead of the last frost. Scatter seed on the surface of the mix and press it in gently, since it needs light to sprout, and keep it moist. Move seedlings into their own containers once they're big enough to handle, and pinch out the tips so plants branch and yield more. Plant out after the last frost, 6–8" apart in rows 18" apart.
To sow in place, wait until after the last frost. Scatter 2–3 seeds per inch in a narrow band on the prepared bed and press them in lightly, as they need light. Keep the soil moist and thin to 6–8".

LIGHT PREFERENCE:

Full sun.

SOIL REQUIREMENTS:

Does well in light soil of average fertility but won't tolerate drought-dry ground.

PLANT HEIGHT:

Grows about 8–24" tall.

PLANT SPACING:

Space plants 6–8" apart.

HARDINESS ZONES:

Hardy in Zones 9–11.

HARVEST:

Cut whole plants as they start to flower. To dry, hang small bunches upside down somewhere dry, airy and out of direct sun.

SCIENTIFIC NAME:

Origanum spp.
