How long do French marigolds last?
French marigolds (Tagetes patula): Classic annuals (4-6 months) African marigolds (Tagetes erecta): Larger, slightly longer-lived (up to 8 months) End of Life Cycle: As annuals, marigolds will complete their life cycle within one growing season, typically from spring through fall.

Flowering attracts pollinators, enhancing garden biodiversity and beauty. Marigolds typically do not multiply on their own like some perennial plants. However, they produce seeds that can self-sow if allowed to drop and germinate in the surrounding soil. Also, marigolds can be propagated by taking cuttings or dividing established plants to create new ones.Marigolds release chemicals into the soil that can disrupt the regular growth of some plants. Scientific studies have shown that these chemicals can inhibit germination of cabbage, brussels sprouts and other brassica crops. Avoid sowing these crops where marigolds have been grown or are currently planted.The ideal soil pH for marigolds is between 6 and 7.
