Step 1

The Plants are Grown from Tubers

Part of the Sunflower Family

Purchase the Tubers

Jerusalem artichokes are actually members of the sunflower family. They are grown for their edible tubers that have a taste similar to artichokes. The plants are grown from tubers planted in spring. Popular varieties include Fuseau, Red Fuseau, and Stampede.

Step 2

Prepare the Site

Jerusalem artichokes can grow just about anywhere, but they do best in raised beds with good drainage. Because they grow very tall, they should be placed on the north side of the garden. Work a generous amount of compost and soil conditioner into the bed to a depth of 12".

Step 3

Select tubers with two or three buds for planting.

Plant Jerusalem Artichokes Tubers

Plant the Tubers

Select whole tubers or pieces of tubers with two or three prominent buds for planting. In early spring, plant the tubers 4" deep and 24" apart in all directions. Cover with soil and water well. Add mulch to the beds to keep the dirt in place and to hold in moisture.

Step 4

Check beds for weeds and slugs.

Water for Deep Roots

Cultivate the Plants

Jerusalem artichokes need to be watered deeply to force the tubers to grow down and out rather than up toward the surface. Carefully pull any weeds that appear and keep a look out for slugs until the plants get well established.

Step 5

Plant Small Tubers for Next Year

Harvest the Tubers

Harvest the Jerusalem Artichokes

When the foliage begins to change color and die back in the fall, cut the plants down to 12" above the ground. The tubers can be dug up with a pitch fork as necessary, but those left in the ground after the first hard frost will taste sweeter than those pulled before it. Immediately replant the smallest tubers for next year’s crop.
