What are common fungi that affect gardens?
Fungal infections in gardens can manifest in various ways, with some of the most common culprits being powdery mildew, root rot, and rust. Powdery mildew typically appears as white, powdery spots on leaves and thrives in humid conditions. Root rot, often caused by soil-borne fungi, can lead to wilting and yellowing of plants, as it attacks the roots and prevents uptake of nutrients and water. Rust is another problematic fungal infection that appears as orange or brown spots on plant leaves and can severely harm plant health.
These fungi can be detrimental not just to the aesthetics of your garden but also to plant health and productivity. When left unchecked, they can spread rapidly, affecting multiple plants and even entire crops. Recognizing these fungi early is essential for effective control and mitigation.
