How does root rot typically develop?

Root rot typically develops from high moisture levels in the soil, which is often a result of excessive watering. When the soil remains saturated for extended periods, it creates an environment conducive to the growth of pathogens such as fungi and bacteria that cause root rot. These pathogens thrive in wet conditions, and they begin to break down the root tissues, leading to rot.

A well-drained soil is essential for healthy root development, as it allows for proper oxygen exchange and prevents the roots from sitting in waterlogged conditions. While factors such as excessive sunlight, low soil temperatures, and nutrient deficiencies can affect plant health, they do not directly cause the conditions that lead to the onset of root rot like high moisture levels do.
