Causes of Root Dieback

Root dieback can be caused by a variety of factors, including:

Overwatering: When the soil is consistently waterlogged, the roots may begin to rot, leading to dieback. This is especially common in plants that are sensitive to moisture, such as ferns and peace lilies.

Poor Drainage: If the potting mix does not drain properly, water can accumulate in the soil, causing the roots to rot.

Root Bound Conditions: When a plant has outgrown its container and needs to be transplanted, the roots can become constricted, leading to dieback.
