(Best months for growing Jerusalem Artichokes in USA - Zone 5a regions)

  • P = Plant tubers
  • Easy to grow. Plant tubers about 5cm (1.5") deep.. Best planted at soil temperatures between 8°C and 15°C. (Show °F/in)
  • Space plants: 30 - 45 cm 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 1.5 m 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.

It took a while but I have learned to love Sunchokes. Undoubtedly the easiest and most prolific vegetable of them all. But what to do with them ? Boil them, roast them, grate them into salads, slice them into stir fry. I use them mainly as a filler. They thicken soups and stews and I mash them up with my spuds. Very economical. they don’t have a long shelf life (which is why they are ridiculously expensive) so I tend to leave them in the ground until I use them. If you have a lot of sunchokes - and you will - you can be brutal when you peel them. But keep the peelings out of the compost or you’ll end up with sunchokes everywhere ! Warning : They can be ‘noisy’. Not recommended for date night or before attending the cinema.

My Jerusalem Artichokes had very few tubers. Almost nothing. The soil is semi-sea sand in a winter rainfall area. The colour of the soil is like sea sand. What can I add specifically for Artichokes?

Buy in some good soil and add compost manures etc.

There's a yellow flowering bush that looks like Jerusalem Artichoke that grows wild around northern rivers- Uki NSW Australia that seems similar but flower looks a bit bigger & grows quite tall & I think the leaves are wider with a different shape, not ovste like the Sunchoke. Does anyone know if these plants that can run rampant are from the same family as the Jerusalem Artichoke?
