Garden Soil

Soil Type

Water: French marigold thrives in warm climates and requires consistent moisture. It is moderately drought-tolerant but flourishes with steady humidity. Weekly watering supports growth, while rainwater during the growing season enhances its blooms for this annual flowering plant often cultivated outdoors.

Fertilize: French marigold thrives in various conditions and usually needs no extra fertilizer unless the soil is poor. To extend its blooming, topdress with Compositae fertilizer in the evenings, and dilute this special fertilizer 15 days before blooms, storing nutrients for enhanced flowering.

Pruning: French marigold thrives with vibrant blooms and pest-repelling qualities. Light pruning promotes lush growth, while regular deadheading and a thorough spring trim enhance airflow, aesthetics, and health. These practices stimulate new blooms and prevent diseases, ensuring continuous flowering.

Propagation: French marigold propagates best through sowing in well-draining, aerated soil. Lightly cover seeds for germination, requiring some light. Maintain moisture without waterlogging for healthy seedlings. Once true leaves appear, transplant with adequate spacing for air circulation.
