How to Jerusalem Artichoke

Jerusalem Artichokes are nothing like their cousin the Globe Artichoke.

Jerusalem Artichokes are a tuber, or root crop, and tastes somewhat like potatoes with a nutty flavor. The plants grow six to eight feet tall with sunflower like blooms. They are very uncommon in the home garden. Their lack of popularity stems more from lack of awareness than flavor.


  • There are few varieties of Jerusalem Artichokes.

Planting Artichokes:

Jerusalem Artichokes like soft soil, rich with plenty of compost and good drainage.

Plant Artichoke and grow them just like potatoes. Sow "eyes" three to four inches deep. Separate 18 inches in the rows, and space rows three feet apart.

Grow and care for Jerusalem Artichokes like potatoes. Mound dirt up around the base of the plant and make sure tubers are covered.

Application of fertilizer and mulch will be rewarded by healthier plants, and a larger harvest.

Insects and Pests:

Slugs and snails like the leaves and stems. Root maggots can sometimes infest the tubers, but not often.

Disease: Blights and fungus can affect plants, especially in wet, humid weather.

Harvesting Artichokes:

Harvest  Artichokes late in the season for individual meals, being careful not to disturb the root system any more than necessary. After the first frost in your area, dig out the remaining roots.


Jerusalem Artichokes are very susceptible to frost. But you can be growing artichoke right up to the first frost.

If frost is in the weather forecast, cover up artichoke plants to extend the growing season.
