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?

I'd also be keen to have some tubers for growing if you still have some available (have fond memories of eating them as a kid from my fathers large garden). Happy to pay postage. Thanks

Ask around nurseries or go on the internet and try and find garden clubs in NZ.

Does anyone have any JAs at this time of the year? I'm looking for up to 15 kilos but any amount ok. Jan 2018

Hi Phillip, I have 15kgs of JAs if you are still looking. Growing beautifully pretty much in the deep south. Will still have then in Jan next year.
