Why are my blueberry leaves turning black?

Is Epsom salt good for berries?

Why are my blueberries small and shriveled?
Anthracnose fruit rot Fruit Infections may occur from bloom to fruit ripening. This fungus causes the berries to “leak” and have a shrunken appearance, especially near the blossom end of the fruit. The blossom end of blueberries will shrivel first, following anthracnose infection.
Why did my blueberry leaves fall off?
Defoliation of blueberry plants may be a sign of fungal infection. For example, phytophthora root rot, caused by Phytophthora cinnamomi, is most severe during spring and fall and causes leaf symptoms that include chlorosis, reddening and defoliation.
