Planting and Caring for Marigolds
Proper planting and care are essential for marigold success. Consider these factors:
When to Plant
Marigolds thrive in warm weather. Plant them after the last frost, typically in late spring or early summer.
Soil Requirements
Marigolds prefer well-drained soil with a slightly acidic to neutral pH (6.0-7.0). Amending heavy clay soil with compost or other organic matter will improve drainage;
Sunlight Needs
Marigolds require at least six hours of direct sunlight per day to produce abundant blooms. Choose a sunny location in your garden.
Watering and Fertilizing
Water marigolds regularly, especially during dry spells. Avoid overwatering, as this can lead to root rot. Fertilize lightly with a balanced fertilizer every few weeks to promote healthy growth and flowering. The following table outlines a good fertilization schedule.
| Stage | Fertilizer Type | Frequency |
|---|---|---|
| Planting | Slow-release granular fertilizer | Once at planting |
| Growth | Balanced liquid fertilizer (10-10-10) | Every 2-3 weeks |
| Flowering | Fertilizer high in phosphorus | As needed |

- Spider Mites: Tiny pests that can cause yellowing of leaves. Treat with insecticidal soap.
