Causes and prevention strategies for mold spots on the surface of potted plant soil

The Causes and Control Methods of Fungal Spots on the Surface of Potted Plant SoilCauses of Fungal Spots on the Surface of Potted Plant Soil1. High humidity: Excessive watering for a long time or poor soil drainage can lead to consistently high soil moisture, providing a breeding ground for mold.2. Poor soil aeration: An excessive amount of organic matter in the soil, such as withered leaves and rotten roots, can reduce soil aeration, leading to insufficient oxygen in the soil and favoring mold growth.3. Imbalance in soil pH: Soil that is too acidic or too alkaline can affect the normal growth of plants and also provides conditions for mold to reproduce.4. Improper placement of potted plants: Placing potted plants in dark and humid areas, such as near bathrooms, can easily lead to fungal spots on the soil surface.Control Methods for Fungal Spots on the Surface of Potted Plant Soil1. Ventilation and aeration: Maintain good ventilation around the potted plants, avoid prolonged humidity, and adjust the placement position appropriately to prevent placing potted plants in dark and humid areas.2. Control watering: Reasonably control watering to avoid excessive watering, and check the soil moisture promptly after watering to ensure good soil aeration.3. Appropriate fertilization: Choose fertilizers suitable for potted plant growth and fertilize reasonably. Over-fertilization can lead to an excessive accumulation of organic matter in the soil, reducing soil aeration.4. Soil disinfection: Regularly disinfect the soil to kill the mold in the soil. Soil disinfection can be performed using disinfectants such as potassium permanganate and carbendazim.5. Replace soil: When the soil has poor aeration or an imbalanced pH, it can be appropriate to replace the soil, choosing specialized potted plant soil with good aeration and suitable pH.6. Pay attention to plant placement: Avoid placing potted plants of different types together to prevent them from affecting each other's growth.Although the problem of fungal spots on the surface of potted plant soil is common, it can be effectively prevented and resolved through reasonable maintenance methods.
