Q.Sour Blackberries
Why are my blackberries sour? The plant itself is beautiful and the blackberries look fabulous, but when you eat them, UGH! They’re sour. I’ve had the plant for about 5 years and it’s the same every year. Not a sweet one yet!

My guess would be that you may simply be picking them too early. Most people tend to pick blackberries when they are a nice glossy, dark color when in fact you should wait for them to dull in color before harvesting.
