(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 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 1.5 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.

I just harvested the jerusalem artichoke that we planted last spring. The flowers were done but the plant was still alive. I have lots of small tubers and thick root with sprouts. Is all this OK to cook and eat?

Yikes, I thought I could grow Sunchokes in zone 5 and bought a few. What do I do now? Can I still plant them in sunny spot or eat and wait next year? Are they still good if they got soft? I forgot them in the garage for a week. Thanks!

An old timer told me if you wait until after the first frost to harvest the tubers they cause much less flatulence. He said before the first frost they call them fartichokes. : ) Planting for the first time this year and will definitely apply this advice.

I bought 5 tubers from Amazon, they're huge, about 4" wide! Can I cut them to make more plantings? Also, it says to plant in February, how do I store then until then? Don't want them to rot!

Store them in a pot of dry dirt. Cut them a cpl days before planting to allow the cut to scab over. best if you can dip wet cut in wood ash so that insects dont find it attractive.

I live on the Alabama Gulf Coast, and just bought 4lb Jerusalem Artichokes for planting. Can I plant now (October) or if I need to wait until Spring, how should I store them? Should I mulch if I plant now? Thank You

I finally got some Jerusalem Artichokes from a grocery store for $4.99 a pound and cooked them. I like them but primarily because my doctor called them a Superfood for me. But saved 4 to plant is it too late, April to October, right?
