Mexican Mint Marigold - Key Growing Information

Mexican mint marigold petals and leaves are edible; plants thrive in hot, humid climates, prefer full sun and well-draining, even sandy soils.

DAYS TO GERMINATION:

Usually 5–15 days.

SOWING:

Transplants are recommended: sow 1/8" deep in seed mix 6–8 weeks before the last frost. When seedlings are a few inches tall, pinch the tips so plants branch and don't flop over (lodge) in wind, then pinch again two weeks later. Harden off and plant out after the last frost.
To sow in place, plant ¼" deep after the last frost. Thin and pinch once true leaves show, leaving plants 8–12" apart in rows 18" apart.

LIGHT PREFERENCE:

Full sun.

SOIL REQUIREMENTS:

Needs average to good soil with good drainage. Too much fertilizer gives soft, lush growth with weak flavor and few flowers.

PLANT HEIGHT:

Grows about 16–20" tall.

PLANT SPACING:

Space plants 8–12" apart.

HARDINESS ZONES:

Hardy in Zones 8–11.

HARVEST:

Pick leaves all season for fresh or dried use. North of Zone 8, you can dig plants in fall, keep them indoors as houseplants, and set them out again next spring.

SCIENTIFIC NAME:
