What to Do About Root Rot in Peace Lilies? Causes and Remedies Explained
1. Water reasonably
Cause: Whether it is prolonged dryness or prolonged waterlogging, both will damage the roots of the peace lily and cause them to rot.
Solution: Improve the watering method; do not water too much and do not go a long time without watering.

2. Fertilize reasonably
Cause: Applying too much fertilizer, or applying raw fertilizer which burns the roots, can both trigger root rot.
Solution: Improve the fertilizing method, use decomposed fertilizer, and follow the principle of applying light fertilizer frequently.
3. Raise the temperature
Cause: Low temperatures can cause freeze damage to the roots in the soil, which can also cause root rot.
Solution: Increase the temperature appropriately.
4. Severe root rot
If the root rot of the peace lily is relatively severe, it needs to be taken out of the flower pot and the original soil removed. Then use sterilized tools to trim away all the rotten roots, and place it in river sand, plain soil or water to grow new roots. Once new roots have grown, replant it.
