how long does it take for marigolds to flower from seed
Depending on the variety, marigolds can grow 8 to 40 inches tall, and develop blooms that can range in size from 1 to 5 inches. For germination within about five to 10 days, start the seeds indoors six weeks before the last spring frost and expose them to ideal conditions.tart marigold seeds in a seed-starting flat that's filled up until 3/4 inch from the top with sterile, moist, seed-starting mix. Sprinkle the seeds on top of the medium and sow them at a depth that equals two to four times the diameter of the seeds.
