Blueberries are sensitive and require acidic soil. When you get that right they can pay for themselves, although they tend to be cheaper by weight than raspberries store-bought here (ymmv).

Blackberries are a scourge and I wouldn’t recommend anyone to grow them, especially in a variety garden. They spread rapidly, suffocate anything they touch, have thorns everywhere, and they are nigh impossible to get rid of. It’s great to have on the edge of your garden - if you hate your neighbor.

If raspberries were dog, blackberries would be rabid wolfs. I don’t even care if the fruit was golden.

Not all languages say “Pterodactyl” with a silent P.
