What are Leaf Spot Diseases?
An assortment of leaf spot diseases strikes native and ornamental vegetation. They damage plants by interfering with photosynthesis. Fortunately, most leaf spot diseases affect a fraction of any plant’s total leaf area, creating only a minor threat to its health.
Fungi cause the majority of leaf spot infections, though bacteria and other pathogens also produce cause them. The pathogens are spread by wind or precipitation, which give them a scattered appearance on leaf surfaces. Moreover, many such infections are host-specific and affect trees and shrubs within the same family.
How to Identify Leaf Spot Diseases
Leaf spot diseases manifest in a wide range of shapes, colors, and sizes. Thus, spots are about the only common signs among them. Leaf spots may be jagged or round, raised or sunken, and with colors ranging from yellow to red-orange, beige, brown, or black.
Plants may exhibit various-sized leaf spots, though those with smaller spots exhibit a younger infection while larger spots indicate an older one. Oftentimes, the disease first appears on inner, lower branches due to their ample shade and humidity.
Management of Leaf Spot Diseases
Although leaf spot diseases tend to cause little harm, they should be addressed if moderate to full leaf loss occurs in an infected tree for 2–4 years straight. Otherwise, the plant will experience reduced growth and greater vulnerability to pests and other diseases. Fortunately, many leaf spot diseases possess similar biology and thus can be managed through identical methods. Mitigation starts with simple routine maintenance.
First, do not overcrowd plants. Allow for sufficient space and trim regularly to ensure proper light penetration and air circulation. Also, water plants at the base and ensure the leaves are dry. Finally, rake fallen leaves before snowfall to avoid reinfection during the next growing season. With diligent maintenance, you can reduce the occurrence of leaf spot diseases. When more than routine maintenance is needed, however, contact an expert arborist to determine if tree removal is necessary.
