I planted arapaho varity blackberries and I believe one navaho, years ago and have never had a decent berry from them. All so sour. I have raspberry bushes growing next to them that are ohh so sweet.
I have waited till they were almost off the vine ripe and no luck. Dull or shiney they are tart and sour.
Are there better varieies or should I stick with my gold and red raspberries and give up on blacks.
I do have some wild blackberries that I took from a friends property in Vermont that are doing ok. They might produce this year. They are sweet as can be when we pick them up North.
