I would just put a few back in the ground. They'll regrow in spring. Very hard to kill.

I keep mine in a plastic bag at the back of the fridge... checking now and again to make sure they don't get wet. They last for months for eating (but I haven't tried replanting those).

My j/a are 3mtrs tall with lovely flowers, and are growing like wildflowers they are absolutely lovely, this is their 2nd season growing. I watered them everyday with plenty water. The tubes are massive. Not eating yet, just want them to grow. I live in Murupara, NZ.

Wow, sounds like the height hasn't lowered your yield, I will await and see what happens with mine :) As I am Tauranga area I am guessing similar climate

Do you still need some j/a, the bottom leaves are slowly going btown

My boysenberry and blackberry plants are 'running rampant' I 'nipped' the ends out but now there is twice as many shoots going everywhere. Should I cut back now to encourage the 'bits' that will fruit next season or wait for autumn

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?
