Boxwood blight is a fungal disease that affects boxwood plants, causing significant damage to their foliage. The disease is caused by the pathogens Cylindrocladium pseudonaviculatum and Cylindrocladium buxicola, which thrive in warm, humid conditions. Infected plants may show symptoms such as dark spots on leaves, leaf drop, and overall decline in health. This blight can spread rapidly, especially in dense plantings, making early detection crucial. To manage boxwood blight, gardeners should practice good sanitation, remove infected plants, and avoid overhead watering. Preventive measures, such as using resistant varieties, can also help protect boxwoods from this disease.
