How Do I Make by Blackberries Sweeter?

Question

My blackberries are quite large and juicy but do not have the sweetness that the raspberries do. They grow in the same soil and are fairly close together. Any ideas would be helpful.

Answer 1

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.
