Root rot is one of the most common problems affecting indoor plants. It occurs when roots sit in waterlogged, low-oxygen conditions for too long, causing the roots to weaken, decay, and eventually die. Once roots begin to rot, pathogens such as fungi and bacteria often follow, accelerating the damage.
Healthy roots need both moisture and oxygen to function properly. When soil stays constantly wet, oxygen levels around the roots drop, preventing them from absorbing water and nutrients effectively. Common signs of root rot include yellowing leaves, drooping foliage, soft stems, and a sour smell from the soil.
The best way to prevent root rot is through good plant care and proper soil structure. Always use pots with drainage holes so excess water can escape. Choose a potting mix that remains light and airy, allowing oxygen to reach the roots. Adding materials that improve drainage, such as perlite, can help create a healthier root environment.
Most importantly, only water when the plant’s root zone has dried enough, rather than watering on a fixed schedule.
