Allotments 4 All

I have some stands of wonderful looking raspberry canes with wonderful looking fruit on them.

However, they taste manky.

Other stands have all sorts of cane diseases(they are coming out this year)but still manage to produce luvverly raspberries.

What's going on?

Even the chickens rejected the perfect-looking ones!

Dunno? I only grow Autumn Bliss and they haven't ever let me down..  :-\
