French Dwarf Marigolds are low-maintenance and thrive in full sun with well-drained soil.End of Life Cycle: As annuals, marigolds will complete their life cycle within one growing season, typically from spring through fall. Once they have produced seeds, they die and do not return the following year.While marigolds may bloom throughout the year in warm climates, they are annuals and the plants will die back in winter in cool climates and after they have finished flowering in other areas.When growing marigolds, check soil weekly: When the top inch is dry, it’s time to water.

What not to plant with French marigolds?

Avoid planting near beans, as marigolds can inhibit their growth.French Marigolds are highly effective at deterring a variety of garden pests due to their strong scent.

What are common French marigold problems?
French marigolds thrive in full sun, needing 6 to 8 hours of sunlight daily to flourish. Another issue could be a nutrient deficiency. A lack of phosphorus and potassium can significantly affect bloom production. Lastly, overwatering can lead to root rot, which severely impacts plant health and flowering. Low soil pH and bacterial infections can cause the leaves to brown. Brown spots can be caused by bacterial leaf spot, or an excessive amount of iron. Marigolds do not grow well in soils that have low pH, and this can lead to iron toxicity. A soil test can help determine if you have a low soil pH.
