Planting Jerusalem Artichokes (Sunchokes)

I had my first taste of sunchokes as a child living in California - a long time ago, Since then, I didn't see sunchokes or Jerusalem artichokes as I knew them, until a couple of years ago when we were shopping in a large Korean grocery market. I looked at my husband, Eric and excitedly showed him the package of three or four tubers on a Styrofoam tray wrapped in cellophane, fully expecting him to reciprocate my enthusiasm but instantly seeing his doubt. After I briefly explained my experience, he agreed that we should at least try them, so we brought them home. 

That was the beginning of the explosion of sunchokes all over our property! I planted the three or four tubers along our driveway envisioning three or four flower plants gracing our yard with tubers for harvesting in the fall. Instead what happened was that I almost forgot about them as our yard became a massive construction site as we lifted our home 8 feet higher for flood protection.

The following spring, I noticed new little plants springing up where I planted them but also several on the other side of the driveway. I let them grow and enjoyed the tall plants and bright yellow flowers after the fall equinox. When the frost killed them back to the ground, I pulled up some of the dried stems and found several tubers under each plant, which I was thrilled to try my hand at cooking. We tried roasting them simply in the oven, boiling them with mashed potatoes, adding them to soups, and really enjoyed our new crop - although they never seemed as good as when I was a child eating them for the first time.

A year later, our yard exploded with sunchokes popping up everywhere. I will mention that we love growing all sorts of plants and are in the process of turning our lawns into food forests so we were not concerned about the invasiveness of this plant since it was not just a food source but also a beautiful flower. However, you can keep them under control by simply mowing the young plant, or planting the tubers in large planters and cutting the blooms before they go to seed.

So just how do you plant sunchokes?

Since sunchokes are often harvested in the late fall, you can plant right away, or store them as you do other flower bulbs, in a slightly damp material like sawdust or sand in an unheated garage in the dark. Either way, you want them to stay dormant until spring.

1. Prepare a hole about 6 inches deep in rich soil with plenty of organic matter and in full sun
2. Set the tuber in the hole and cover with soil, firming the soil until the hole is filled.
3. Water the area lightly if the soil is not damp.
4. Wait for the tuber to grow!

That is really how easy they are. You can plant them in the late fall, or the  middle of winter if you can get a fork in the ground or early in the spring. They are very hardy and don't seem to have many pests, besides maybe some aphids in the early summer.
