Marigolds Wilting in Connecticut: Too Wet, Too Dry, or Root Rot?

A longtime marigold grower in CT faced sudden failure: plants wilted, dried, leaves soft. Different varieties, different nurseries, same poor results. One container plant missed 2 days water, wilted, didn't recover after replanting in rich soil.

Diagnosis Checklist

• Marigolds prefer dry side: Sunny, well-drained. Hate wet feet.
• Shade creep? Formerly sunny spots may now be shadier.
• Wet summer? Excess rain causes root rot—wilting because rotted roots can't uptake water.
• Repeated drought cycles? Damages root system.
• Slugs? Chew stems at base, causing top wilt.
• Soil pH extremes? Very acid/alkaline weakens plants.

Recovery

If cut back below 3", unlikely to return. Improve drainage, avoid overwatering, check for slugs, test pH. Marigolds thrive on neglect—lean soil, full sun, dry conditions.
