(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 1.5m-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.

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?

Where can i buy a few tubers of jerusalem artichoces, some for eating and some for planting in the northern freestate.

Hi Henk, Livingseeds carry them. Their site shows it as out of stock for most of the year and usually show available stock in early winter.

Popped mine in poor soil about 3 inches deep in Nov (I read they don't like rich, amended soil). Haven't seen anything yet. Maybe sunchokes in zone 10b is a problem?

The planting guide here says they won't grow in your zone.

I have had a scratch and they are producing tubers, so they don't have to flower.

This is my first attempt at growing Jerusalem artichokes. I'm in a temperate zone and planted them in November. Only one plant has produced one flower! Will this be a problem?
