Leaf Spot Fungal Diseases

Posted by John Fulton -

It seems the leaf spot fungal diseases are present with a vengeance. Anthracnose and apple scab are very noticeable now. If you think your trees have escaped infection, hold a leaf up to the light to make sure. If you see light areas along the edges or between veins, you'll probably have the full-blown symptoms within a week.

As there is no cure, keep the plants watered with an inch a week during dry spells. A little fertilizer also will help. Severe leaf drop early in the season will usually lead to another set of leaves being out in four to six weeks.
