Coleus Collapse: Overwatering Diagnosis and Recovery Protocol

Coleus leaves turning yellow (green and red both), falling off in handfuls, stems going limp? Classic overwatering. Roots suffocated, can't transport water—plant wilts despite wet soil.

Immediate Action

1. Stop watering completely until soil is bone-dry (rock hard)
2. Then water deeply every few days—only when top 1" is dry
3. No fertilizer for 2+ weeks
4. Do not repot, disturb roots, or "help" further—let it recover

Why This Works

Roots need oxygen. Constant moisture fills pore space, drowning them. Drying out restores air exchange. Surviving roots (40% leaves = living roots) will regenerate.

Prevention

• Water only when top third of soil is dry
• Deep soak, then wait
• Ensure drainage holes work

Reality Check

Severe cases may not recover. But coleus are resilient—if stems stay green, they usually bounce back in 2–3 weeks.
