1 Though they grow in almost any soil, marigolds thrive in moderately fertile, well-drained soil. 2  Sow them directly into the garden once the soil is warm, or start seeds indoors about a month to 6 weeks before the last spring-frost date.3  The seeds germinate easily, but watch out for damping off if you start them inside.hen fertilize lightly with a balanced plant food. It may take a week or two for the marigolds to recover but they should be fine. Next year, if you grow marigolds, you really want to pinch or cut back the new buds and foliage tips when they are 6 to 78 inches tall.
Within one or two months, your vine should measure 6 to 10 feet and your first moonflowers should bloom. The first flowers will be small -- 3 to 5 inches across -- but eventually your moonflowers should measure up to 6 inches across. By late June or early July, the plant should be covered with blooms. Moonflowers may take five or six months to bloom after planting, which is why you should plant the seeds in late February or early March. Gather ripe seed pods after they turn brown, beginning in October.
