Problems With Blackberry Plants
I'm getting a low amount of fruit this year (three year old plants), and the fruit I get is odd looking. About two thirds of the berry drupelets are black, but the rest are an unripe pale color. They're not too sweet either. Help!

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.
