Facts. 1  Tall marigolds are sometimes labeled African marigolds, and the dwarf kinds are often called French marigolds. 2  Tall marigolds (Tagetes erecta) grow anywhere from 15 inches to 4 feet tall with blooms that can reach up to 5 inches across.
This will improve soil drainage and fertility. Plant marigold seeds in the soil 1/4 inch deep and water the area deeply. The appropriate spacing for marigolds depends on the mature size of the plant. French marigolds (Tagetes patula) are smaller plants and can be spaced 6 to 9 inches apart.The larger African marigolds (Tagetes erecta) need around 18 inches of space between plants.hen 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.
