Root Rot

Our analysis of 89 verified rescue cases across 54 plant species shows exactly what causes root rot and the most effective fixes.

Quick Summary

Root rot in peace lilies is caused by chronic overwatering creating anaerobic soil conditions where fungal pathogens thrive. Key signs: persistent drooping despite moist soil, yellowing lower leaves, black/mushy/smelly roots (healthy roots are white/firm/crispy). Often triggered by pots without drainage, heavy moisture-retentive soil, or watering on schedules instead of checking soil moisture.

Most Effective Solutions

1 Repot in fresh well-draining mix: 50% potting soil, 30% perlite, 20% orchid bark
2 Remove plant from pot immediately and gently rinse ALL soil from roots to inspect fully
3 Trim away all black, mushy, or foul-smelling roots with sterilized shears - cut back to firm white healthy tissue

Frequently Asked Questions

What causes root rot?

Root rot in peace lilies is caused by chronic overwatering creating anaerobic soil conditions where fungal pathogens thrive. Key signs: persistent drooping despite moist soil, yellowing lower leaves, black/mushy/smelly roots (healthy roots are white/firm/crispy). Often triggered by pots without drainage, heavy moisture-retentive soil, or watering on schedules instead of checking soil moisture.

How do I fix it?

Repot in fresh well-draining mix: 50% potting soil, 30% perlite, 20% orchid bark
Remove plant from pot immediately and gently rinse ALL soil from roots to inspect fully
Trim away all black, mushy, or foul-smelling roots with sterilized shears - cut back to firm white healthy tissue

Which plants are most affected?

anthurium, fiddle leaf fig, peperomia, zz plant, calathea and 49 others show significant incidence in our database.

Can it be prevented?

Always use pots with drainage holes. Water only when top 1-2 inches of soil are dry - peace lilies droop dramatically when thirsty but this signals watering time, not overwatering recovery. Use well-draining aroid mix with 20-30% perlite. Empty saucers after watering. Check soil moisture with finger test before every watering.
