My first year JAs are well over 2 meters with no sign of flowers, have I given them too much water or does this mean a huge first crop?

I think you need to read the notes here. You eat the root in the ground - nothing to do with the flower I feel. Probably too much nitrogen and watering to have 2m plants.

Thanks Mike, yes I know to eat the tubers [luv them, my Father always had them in the vege garden-many years ago] think from your answer I may have watered too much. Was hoping as they had grown so tall that the tubers would be more, but...... I have read somewhere since posting my query, that if one stops them flowering a bigger crop is produced?
