Yoshino cherry trees losing leaves. I have three Yoshino cherrys that have been in the ground about 7 years and are about 8 feet high.
Many leaves are yellowing and falling off. Whats there looks healthy but many branches are going bare. We have been having a rather dry spring and I'm wondering if these mature trees need watering.
Affected leaves often turn yellow and drop prematurely. Cherry leaf spot occurs on both sour and sweet cherries in Iowa.
Mild wet weather in spring creates a favorable environment for cherry leaf spot. The cherry leaf spot fungus survives the winter on dead leaves on the ground.

The Yoshino cherry tree is native to Japan, China and Korea. Cherry leaf spot is caused by Coccomyces hiemalis. Spots on the leaves, 1 to 3 mm in size, become yellow progressing to brown, and heavily affected leaves turn yellow and fall.
Trees can be completely bare by midsummer if the infection is severe. The fungus survives in fallen leaves, so leaf removal can help prevent infection.
