Marigold Red French, a variety of Tagetes patula, is known for its vibrant red-hued blooms.

Here’s a guide on how to grow them:

1. Climate and Soil: Red French marigolds thrive in full sun and well-draining soil. They’re adaptable to various soil types but prefer soil that’s not overly rich or heavy.
2. Planting Time: Sow Red French marigold seeds directly into the garden after the last frost date in your area. You can also start seeds indoors 6-8 weeks before the last frost for an earlier start and transplant seedlings outdoors once they’re established.
3. Seed Starting: Plant the seeds in well-prepared soil, barely covering them with a thin layer of soil. Space the seeds according to the mature size of the plant, typically around 8-10 inches apart.
4. Sunlight: Ensure Red French marigold plants receive full sunlight for most of the day (at least 6 hours of direct sunlight).
5. Watering: Water marigolds regularly, especially during dry periods. Avoid overwatering to prevent issues like root rot. Allow the soil to dry slightly between waterings.
6. Fertilization: Marigolds usually don’t require heavy feeding. Incorporating organic matter like compost into the soil before planting can provide necessary nutrients.
7. Maintenance: Deadhead spent flowers regularly to encourage continuous blooming. Pinching back the stems occasionally can promote a bushier growth habit.
8. Height: Red French marigolds generally grow to a height of about 6 to 12 inches (15 to 30 centimeters).
9. Pest and Disease Control: Marigolds are relatively resistant to pests and diseases. However, monitor for issues like aphids or powdery mildew and treat as needed with appropriate organic or chemical controls.

Red French marigolds are eye-catching and add a bold splash of color to gardens, borders, or containers. They’re easy to grow and provide bright blooms throughout the growing season, making them a popular choice among gardeners.
