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

Yes I have plenty, can you e-mail your address, I'll send them to you by mail.

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

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?

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

I've been growing these for some years now and am a huge fan. Absolutely LOVE them. So do my chickens, turkeys, horses, sheep, cattle and dogs. All except dogs will eat tops and tubers. Dogs only eat the tubers. Cats don't much care for any part of them tho. Cooking tips: I like them best roasted. Cut into 1" x 1" (2cm x 2cm) or so, put on a cookie sheet, drizzle with olive or coconut oil, salt, pepper maybe a little basil or rosemary. Roast at 350F (180C) for 25 - 40 min. They come out about the same consistency as roasted garlic - almost like a paste. Use on a nice cracker with a small slice of cream cheese. Side with a glass of a nice, oaky Chardonnay, a good movie and a sexy friend. I'm done. Night, night. Growing tips: don't do anything to them except give them water and some good manure. If you want to get fancy, cut off the flowers and put them in a vase in the kitchen. (Stripping the flowers puts more energy into the tuber production.) Ungrowing tips: If you want to get rid of them, mow them off once a week and don't water. Turn out pigs or chickens. They will dig up every living morsel and consume it. CAUTION! Do NOT use a rototiller on them. It cuts the tubers into microslices and only encourages them to propagate. Enjoy your sunchokes. They are a gift from the gods.
