How Do You Grow Sunchokes?

Sunchokes are related to sunflowers and horticulturalists have for many years tried to reproduce the latter’s spectacular results using the former. Sunchokes grow in moist, acidic soil at low altitudes. They need the cooler conditions of temperate zones and sunny exposure throughout the day to flourish. If you live in an area with sunchoke-friendly growing conditions, you can start harvesting them from your garden as soon as they appear. Sunchokes are members of the nightshade family and caution is advised against consuming too many of them as they can be poisonous. You should also avoid planting sunchoke seeds or berries near any livestock or pets. Sunchokes are perennial shrubs that produce fruits year after year. They grow best in moist, poorly drained soil with a slightly acidic pH level, though they will still do well under average growing conditions if they don’t get too much shade and drainage is improved.

How do you grow sunchokes?

Sunchokes are easy to grow from seeds, but if you’re not in an area with a sunchoke patch, you’ll need to start them from cuttings. You can sow them directly in the ground once the weather starts warming up, though they will grow best in cooler temperatures. You can also start sunchokes from seed indoors in late winter or early spring and transplant them outside once they’ve grown at least a few inches tall. Keep the soil moist and don’t let it dry out. Sunchokes grow best in a soil pH of 6.5 to 7.5. You can adjust the soil with a bit of sulfur if you want to alter the pH. To increase the soil’s alkaline (basic) content, mix in a bit of soil that has been enriched with organic matter.

Harvesting sunchoke root

Sunchokes can be eaten raw or cooked, but the young, tender root is best when it’s young and small. You can harvest the roots just as the first beans are coming on, once the stem is about 12 inches long. The smaller the stem, the more sugars the roots contain. Wait until well after the first frost date in your area and take the roots from the outer edge of the plant. You can eat the entire plant, but any fruits that are on the plant are too fibrous and woody to eat.

How to dry sunchoke root

Sunchokes can be dried either by air-drying or in a dehydrator. In the latter case, dry the sunchoke root at 105°F for at least 12 hours or until it measures at least 80% of the original weight. You can also dry sunchokes in a slow oven or by placing them on a screen in a shady area to finish. The most important thing is to ensure that the sunchoke is completely dry before storing it. The root will stay pliable and fresh for almost two years if stored properly.

Storage tips for sunchoke roots

- Store in an airtight container with a hard lid. - Keep sunchoke roots in a cool, dry place. They’ll stay fresh for about two years if stored this way.

Cook with sunchoke root

Sunchokes can be eaten raw in salads, desserts, and other raw dishes, but they are much more widely appreciated for their roasted roots. You can roast the roots either on an oven tray or directly on a grill. The roasted sunchoke root is dark brown and slightly sweet. It can be served as an accompaniment to soups, stews, and other roasted dishes, or it can be mashed and used as a potato substitute in casseroles.


Sunflowers are beautiful plants that produce nutritious seeds. Sunchokes are similar to sunflowers with one exception: they are native to temperate climates, not tropical areas. Growing sunchokes is similar to growing sunflowers, and they produce nutritious roots that are similar in taste to yam. You can grow sunchokes in temperate zones and they grow best in soils with a slightly acidic pH and cooler temperatures. To grow sunchokes, you need to plant seeds and provide them with moisture and slightly acidic soil. You can harvest the sunchoke roots when they are small and tender, and you can dry the roots to extend their shelf life. Sunchokes are a nutritious plant that can be grown for a long time.
