The answer to 'garden disease' is that common garden diseases can have a variety of causes, including fungi, bacteria, viruses, and environmental stressors. Symptoms can include discolored, wilting, or dying plants, as well as the presence of lesions, spots, or other visible signs of infection.
Some common garden diseases include powdery mildew, black spot, and fungal root rots. Proper diagnosis is key to effective treatment, which may involve using fungicides, improving soil drainage, or adjusting growing conditions. In many cases, simple preventive measures like proper watering, pruning, and plant spacing can help avoid garden diseases in the first place.
