The fruit on my mulberry tree is all dried up.

Question

Last year it had what was called popcorn disease. This is a huge tree and this year it put out the fruit but it is dried up and never turned color.

Answer 1

The popcorn disease fungus carries over from year to year. It interferes with the ripening of the fruit and it stays greenish. Collect all the infected fruit and dispose of in trash. See below:
