Powdery mildew and apple scab fungus are two of the most common tree diseases that can be found in Northeast Ohio. Symptoms of powdery mildew include pale yellow or olive green spots on the upper surface of the leaves, while apple scab fungus causes dark spots on the lower surface. Cedar rust is another common tree disease in the area, which leaves pale yellow spots on leaves that turn orange over time. Small black fungal bodies can also form inside the spots and exude an orange liquid.
If you notice a dramatic change in the health of your tree, it is likely due to a tree disease or insect infestation. Early detection is key to treating these issues and restoring your tree's health. Underground irrigation can also help improve tree health in drought-prone areas or during times of extreme heat or dry soil conditions. Working with a local professional tree care company is the best way to ensure your trees are healthy and free from disease.
