Does anyone know why most of my soft fruit are bitter? I have logan berries and 2 types of blackberries which were recommended for sweet fruit but all are bitter. Is there anything I shld be feeding them with to improve the sweetness and flavour. Very disappointing.

Are the plants old? Also under watering could cause this and lastly perhaps you have picked them too soon?

Are they growing in full sun? They need this in order to ripen properly and produce good sweet fruit.
