Common Symptoms of Peace lily root rot

When the roots have started to rot, they can be easily spotted. Some of the common symptoms of peace lily root rot are:

The appearance of Black Spots

Black spots on peace lily leaves may not indicate root rot, but rather indicate past suffering or potential root rot. Once bacteria and pathogens damage the plant’s fresh roots, black spots appear on the leaves, surrounded by a yellow hue.

Root rot in peace lily can occur due to various factors, but some common causes include:

Low Light

Peace lilies can survive low light, but it can slow their growth due to reduced photosynthesis and metabolism, causing soil to take longer to dry. Soggy soil damages roots, attracts pests and fungi, and is considered the main cause of root rot.
