Marigolds take around 45 to 50 days to flower after you plant seeds, so seeds sown in early April should flower by May.
When it's time to plant marigold seeds, amend the soil in the area with organic matter, like peat moss or compost. Do this by spreading a 1- to 2-inch layer of organic matter over the surface of the soil, then work the organic matter into the soil with a rake or garden hoe.n temperate coastal climates, where soil temperatures warm quickly in the spring and where spring temperatures are mild, marigolds can easily be direct seeded into the ground at nearly any point in the early to mid spring. The best month to sow marigold seeds is in early April.
