Symptoms of root rot in peace lily


Leaves start Wilting

Leaves get wet and don't get enough nutrients from the air, so they wilt. Overwatering is one of the main causes that can lead to wilt. Overwatering suffocates the plant and leads to the failure of the roots and they fail to supply nutrition to the plant.

Whenever you see droopy or wilted leaves, look for root rot.

Leaves turn yellow

In the autumn the leaves turn a yellow color. This is known to be the big reason for overwatering. When you see yellow leaves on your plants, immediately check the roots as they are trying to tell you that something is not right.

Stunted Growth

Root rot is the main reason for Stunted Growth. This usually happens if the roots have been exposed to wet soil, such as in poorly drained areas.

The most important thing for your peace lilies is to make sure that they have enough light and water (according to the need). If the soil is well-drained, your plants will be happier, and they’ll grow to their full potential.

  • No Roots

    My roots were healthy and because I didn’t completely take it apart to remove all the soil to grow in water the roots are turning brown. I’ve pulled them all apart today and lightly brushed all the soiled out and scrubbed off as much of the yucky dark brown growth off it. I have rinsed if not soaked them in diluted hydrogen peroxide…. now I’m waiting….


    There is another 2x bulbs where the bulbs have dwindled to nil roots…
