French Marigolds are such a great flower for the home gardener.
They offer not only beauty but great companion planting benefits. These flowers are native to Mexico and Central America, but they are commonly known as French Marigolds.
These flowers are different than pot marigolds. There are also African Marigolds which like the French Marigolds are both Tagetes. French Marigolds grow to about 1 foot, whereas African ones grow to about 3 feet.
How to Grow French Marigolds
These flowers are annuals and need to be started from seeds indoors or sown outside after the risk of frost. Start indoors 6-8 weeks before your last spring frost. They start blooming after about 1.5-2 months and continue to flower until frosts. They need 3-6 hours of sun and are excellent inter-planted with other plants. Be sure not to over water them as they’re prone to root problems in soggy soil. You can ‘dead head’ flowers to allow for continuous blooms so the plant doesn’t go to seed.

French Marigolds Repel Bugs
There have been scientific studies that show that Marigolds create their own pesticide against nematodes. If nematodes are really bad in your soil then you can grow French Marigolds as a cover crop leaving the base roots in the soil before winter sets in.
Because they have a strong scent, they often repel many pests.
