They’re delicious, accessible throughout winter, really simple to grow, entirely undemanding, very low-maintenance, and great for novices.

They also have a lower calorie count. There is only one disadvantage, which I will discuss.

Sunchokes and Jerusalem artichokes are simple to grow and look lovely in your yard while also providing nourishment for your home.

However, they can take over an area in some climes, so put plants in an out-of-the-way corner rather than the middle of your flower bed.

You’ll be able to harvest them for many years if you plant them correctly.

Growing Sunchokes In Your House Garden

This plant’s edible portion is the underground roots, known as a tuber, comparable to potatoes and sweet potatoes. These tubers of the Sunchoke are long and bumpy, resembling a hybrid between such potatoes and a ginger root.

They carry no starch before harvesting and only start to develop starch as they are stored for a lengthy period.

To develop stems after winter, it needs to be chilled for an extended period below 40 ° Fahrenheit. In zone 9 and 10, this can be produced yearly from tubers, although the stalks would be shorter and less robust.

Make A New Sunchoke Bed

Choose a location in the yard that receives sufficient sunlight while not shading other growth regions. These plants grow tall and make an excellent screen, border planting, or windbreak.

When they approach their maximum height, plants may have to be grouped to avoid falling over in the wind.

Dig the soil thoroughly and mix with an inch or two of well-composted manure to create a fresh sunchoke bed. Put the tubers in lines 4 to 6 inches thick and 8 to 12 inches apart.

Rows should be spaced 18 to 24 inches apart, enabling a wedding between them. Plant the tubers on 8 to 12-inch centers in a grid pattern over the raised bed if growing in a garden bed to allow for spread. 

The plants can refill in the empty places with fresh tubers in subsequent years, giving you enough tubers to harvest yet preserving some tubers in the soil for the future.

The tubers are sown in the same way that tubers are. Each tuber’s portion should contain one or more “eyes” from which shoots will develop. Plant the tuber 4 to 6 inches deep, “eye” up. Jerusalem artichoke will colonize an area where it is planted.

Planting in rows inside your vegetable garden is frequently not the most excellent option because the plants can extend up to two feet each way. Rather, find a bed where the tubers can expand and develop easily.

How To Harvest Sunchoke Tubers

Sunchokes should be harvested after a first-killing frost, whenever the blossoms have faded away. Frost adds flavor to the tubers.

Gently dig all-around tubers with your hands or a spading fork to soften the dirt and retrieve them for harvesting. You’ll want to be careful not to harm the tuber with the knife, just like you would while harvesting potatoes.

Expect the roots to have grown at least one foot from the stem. Sunchokes will live beneath the snow in zone 3 and higher during the wintertime.

Lift young tubers out of the soil and plant the following season as early as the ground can be worked, around the time you sow your spring pea crop, in zone 2 or locations with no snow accumulation.

Cover with 2 feet of straw or weed-free hay instead, and then remove the mulch in the spring when the ground thaws in the area.


When To Harvest Sunchokes. Sunchoke tubers will just be available for harvest 120 to 150 days after they are planted. Remove flower stalks as soon as they appear to favor tuber production rather than seed production.

That once blooms emerge, plants can be “lodged” by stepping on the stems at soil height and bending them towards the side, channeling vitality to the tubers.
