root rot on Prayer Plant
Quick answer
If your Prayer Plant has root rot, the most likely cause is: Phytotoxicity and root hair damage caused by repeated applications of hydrogen peroxide (H2O2). While effective as a one-time drench for fungus gnat larvae, Maranta's delicate rhizomes and mycorrhizal-dependent root systems are easily burned by prolonged oxidative stress, leading to systemic wilting ('throwing a fit') that mimics the very rot the user is trying to cure.
Start here:
- 1. Immediately stop all hydrogen peroxide treatments.
- 2. Flush the soil thoroughly with distilled or filtered water 3 times to remove chemical residues.

How to reverse root rot on Prayer Plant
- 1
Immediately stop all hydrogen peroxide treatments.
- 2
Flush the soil thoroughly with distilled or filtered water 3 times to remove chemical residues.
- 3

- 4
Increase humidity to 80% to support the plant while it regrows damaged root hairs.
Keep root rot off this Prayer Plant
Limit H2O2 soil drenches to a single application; use biological controls like Mosquito Bits (Bti) for ongoing gnat issues; monitor soil moisture to prevent larvae-attracting dampness.
