P = Plant tubers

  • Easy to grow. Plant tubers about 5cm (1.5") deep.. Best planted at soil temperatures between 46°F and 59°F. (Show °C/cm)
  • Space plants: 12 - 18 inches apart
  • Harvest in 15-20 weeks.
  • Compatible with (can grow beside): Tomatoes, cucumbers
  • Jerusalem Artichoke/Sunchoke
  • Artichoke harvest

These are the edible root of a sunflower. Plant the tubers deep enough to cover with soil. They are quite drought-tolerant, but keep well-watered to grow larger tubers. They grow through the summer to 1.5m-tall sunflowers with a smallish flower. Dig up the tubers when the flowers die down in autumn.

Get a couple of tubers from the supermarket or fruit shop. Two years after planting you will probably have enough to give away. Perennial, if you don't manage to harvest all the tubers they will regrow year after year.

Culinary hints - cooking and eating Jerusalem Artichokes

Scrape clean or peel (add a tsp of lemon or vinegar to the water to stop the tubers browning). Steam, boil, or use in artichoke soup (make with artichokes and some stock). Caution - because they contain 'resistent starch' Jerusalem Artichokes are a great promoter of flatulence in some individuals.

Bunnings sells an 8-pack (Bloomin' Bulbs range) that is available in most stores. (I checked availability for Mackay recently and noticed that a bunch of stores all the way up the coast stocked them as well.) If they don't have any, it might be worth checking Mitre 10. I recall the store in Sarina having some and suspect that it might be something that the chain stocks on a regular basis. Best wishes in finding some bulbs near where you live!

I am ready to harvest my Jerusalem do I leave them in the ground to harvest them again in September or do I pick them now to be planted then?

So if I've just been given tubers (good gardener but never grown them before), they need to be stored like other tubers (spuds/kumaras) over winter? I have a couple of areas on the north side of a stucco house that definitely doesn't get frost - has anyone planted now and managed to overwinter them in the ground ok?

Mike, you can leave the tubers in the ground in warmer areas of NZ, we have done that in Northland. In fact it is difficult to find all the tubers, so they will probably shoot up in the Spring even if you have light frosts.

how do you keep artichokes for the following year for replanting >?

I just leave a few tubers in the ground. They regrow in the spring so long as they get a bit of water. Frost doesn't stop them.

I've just dug up my tubers, in early April - a bit prematurely it appears, as I believe spring is the best time to plant them, August to October. How should I now store them so they won't rot or dry out till then? Or should I just replant them now??
