French Marigold Care Must-Knows
Did we mention how easy they are to grow? French marigolds are often one of the first plants a child will grow—they're that easy! The best soil for growing any type of marigolds is well-drained soil that won't stay wet for long periods. Because they produce so many blooms in a season, they benefit from a regular application of fertilizer.
Marigolds perform best in full sun, which will help the plant grow tall and sturdy and form large, dense blooms and foliage. When planted in part shade the marigold is susceptible to fungal diseases like powdery mildew. Marigolds are also prone to spider mites in the dry heat of the summer, so watch for fine webbing and treat with insecticidal soap as needed.
As a marigold's bloom dies back, pick off the spent blooms. Deadheading will focus the plant's energy on flower production rather than seed production. At the end of the year, if you want to collect seeds for the next spring, leave a few spent blooms and allow them to fully ripen and dry. Note that the seeds will produce plants that are genetically different from the parents, so there may be some variability in flower color and overall plant growth.
Hybridizers are always looking for ways to make this plant do just a little more. Recently, there was a color breakthrough—the first pink marigold, found at online seed retailers. They are also finding ways to make varieties that are more disease-resistant, longer-blooming, and have bigger, tougher blooms.
