Frequently Asked Questions


What pest or disease most commonly affects African marigold (Tagetes erecta), and how can I treat it?
A common issue is powdery mildew on Tagetes erecta, showing as a white, powdery coating on leaves during warm, humid spells. Remove and discard the worst leaves, then improve airflow by spacing plants and watering at the soil line instead of overhead. If it’s spreading, treat with a labeled fungicide that’s approved for powdery mildew on ornamental flowers and reapply as directed on the label.
How often should I water Tagetes erecta during its main growing phase?
During the main growing phase, keep the soil evenly moist but not soggy—aim for watering when the top 1 inch of soil feels dry. Water deeply so moisture reaches the root zone, typically about once every 5–7 days in warm weather, then adjust for rainfall and soil type. Consistently wet conditions promote root issues and leaf disease, so avoid frequent light watering.
How do I know when Tagetes erecta (African marigold) ‘Crackerjack’ is ready to harvest?
Harvest it when the flower heads are fully formed and open for the first time, which for Tagetes erecta is typically around 70 days from seed. Choose blooms that show vibrant, firm petals and have good color with no fading centers. For longest vase life, cut early in the morning and snip the stem just above a healthy leaf node to encourage side branching.
