Marigolds thrive in just about any climate. And although you can sow the seeds directly in your beds in spring, you’ll be able to enjoy their sunny yellow, orange, and bicolored flowers much earlier if you start the seeds indoors.
To start seeds indoors: Sow the seeds about 6 weeks before your last frost date, covering them with a very thin layer of soil. Keep the soil temperature at 70° to 75°F. Sprouts will appear in 5 to 7 days. Plant the seedlings outdoors anytime after the last frost.
