Peace Lily Root Rot Rescue: Fungicide Treatment Over Water Rooting

Saving a Sentimental Spathiphyllum from Advanced Rot

A peace lily with recurring root rot after repotting has a poor prognosis for water rooting—the rot will likely accelerate in standing water.

Recommended Approach

1. Obtain systemic fungicide labeled for ornamental plants
2. Treat remaining healthy root tissue per label
3. Repot in fresh, sterile, well-draining mix
4. Water sparingly—allow top inch to dry between waterings
5. Bright, indirect light; warm temperatures

Why Not Water Rooting?

Water propagation works for healthy cuttings but fails with active rot pathogens. The fungus will colonize the water and destroy remaining tissue.

Sentimental Value

As a memorial plant, consider taking a healthy leaf cutting (if any remain) for tissue culture or as backup. Focus primary effort on saving the original.
