📷 Wikimedia CommonsStarting Mexican Mint Marigold: indoors or direct sow?
🌾 Sow directly in the garden — Mexican Mint Marigold is not usually started indoors.
Direct sow seeds outdoors immediately after all danger of frost has passed, or start indoors right before moving them out once soil temperatures are warm enough for this tender perennial.
Soil, care & harvest
Prepare loose, well-draining soil with a pH between 6.0 and 7.5. As a warm-season tender perennial, you should start seeds indoors after the last frost date or direct sow immediately outdoors once danger of frost has passed. Plant seeds at a depth of roughly one-quarter inch. Expect germination to occur within 7 to 14 days under appropriate warmth.
Space plants 12 to 15 inches apart to ensure good air circulation. This herb requires no support or trellising as it grows low and bushy. Water consistently with about half an inch weekly, though it becomes drought tolerant once established. Apply a light layer of mulch to retain moisture and feed sparingly if growth seems sluggish.
Occasional aphids may appear, but the plant generally resists pests well. Root rot is the primary disease risk, so ensure excellent drainage in your soil. Harvest leaves and flowers starting around 80 days after sowing for culinary use. Snip stems with clean shears to encourage continued production throughout the season.
