Blackberry – White Cells (Dry Cell Syndrome)
Q: I have three blackberry plants that have been growing for three years. This year my crop has been great, but I have a problem with the ripe fruit. I have looked online, and the closest photos I find say that I have Dry Cell Syndrome.
How do I prevent this in the future?
A: I think your diagnosis is correct: dry cell syndrome. Upon investigation, it seems that plant experts are using the word “syndrome” because they can’t decide exactly what causes this problem.
