How to Grow Sunchokes: A Nutritious Root Vegetable
How to Grow Sunchokes?
To grow sunchokes, start by planting 2 to 6-inch deep tubers in loose, well-drained soil with a pH of 5.8 to 6.2.
Space the tubers 12 to 18 inches apart with rows 36 inches apart.
Provide regular water, especially during the growing season, but they can survive drought once established.
They prefer full sun and soil rich in organic matter.
To contain the spread, install at least 24-inch deep barriers in the soil.
Harvest the tubers 120 to 150 days after planting, when the leaves die back.
Cut off flower stalks to encourage tuber development.
Harvested tubers are sweeter after a light frost.
Store them in the refrigerator for up to 10 days or in a cold moist place for 2 to 5 months.

Did You Know?
1. Sunchokes, also known as Jerusalem artichokes, are not actually artichokes nor are they native to Jerusalem. They are a type of sunflower native to North America.
2. The name ‘Jerusalem’ is thought to be a corruption of the Italian word “girasole,” meaning “sunflower,” referring to the sunchoke’s close resemblance to the flower.
3. Sunchokes were a dietary staple for Native American tribes, particularly the Cherokee, who used them both as a food source and for medicinal purposes.
4. When grown for their tubers, sunchokes can reach heights of up to 10 feet (3 meters) and can produce an impressive 25-75 pounds (11-34 kilograms) of tubers per plant.
5. While sunchokes can be a great addition to your garden, they are considered an invasive species in certain regions due to their aggressive spreading habits. It’s important to monitor their growth and control them if necessary to prevent them from taking over other plants.

Growing Conditions For Sunchokes: Soil, Sunlight, And pH Requirements
To successfully grow sunchokes, it is important to provide them with the right growing conditions. These plants thrive in full sun, so choose a location in your garden that receives at least 6-8 hours of direct sunlight each day. Sunchokes also have specific soil preferences, requiring loose, well-drained soil with a pH ranging from 5.8 to 6.2. It is important to ensure that the soil has warmed to around 50°F (10°C) before planting the tubers, as they prefer warmer soil for optimal germination and growth.
Planting Sunchokes: Tubers Depth, Spacing, And Container Options
When planting sunchokes, here are some important considerations:
- Choose high-quality tubers: You can obtain these from reputable online sources or fellow gardeners.
- Plant the tubers at the right depth: Dig a hole 2 to 6 inches deep in the soil and place the tuber inside.
- Space them properly: Ensure that the tubers are placed 12 to 18 inches apart from each other.
- Plant in rows: If possible, plant the sunchokes in rows that are 36 inches apart.
- Containers as an alternative: In case you have limited space or poor soil conditions, sunchokes can also be grown in larger containers. These containers should be able to accommodate the height and spread of the plants.
Remember these key points to successfully plant sunchokes.
Watering And Feeding Sunchokes: Care And Maintenance Tips
Sunchokes require a regular supply of water, especially during the hot summer months. However, once established, they are relatively drought-tolerant and can survive with less frequent watering.
-
Consistent moisture levels in the soil are essential for sunchokes. Uneven watering can cause the tubers to crack or rot.
-
Sunchokes thrive in soil that is rich in organic matter. Consider adding compost or well-rotted manure to the soil before planting to provide these nutrient-rich additions to the plants.
Harvesting And Storing Sunchokes: Timing And Methods
Patience is key when it comes to harvesting sunchokes, as these tubers require approximately 110 to 150 days to reach harvest. The best time to harvest is when the leaves start to die back, which typically occurs 120 to 150 days after planting. To harvest, gently lift the tubers with a spading fork, being careful to avoid damaging them. For sweeter-tasting tubers, consider harvesting them after a light frost. After harvesting, sunchokes can be stored in the refrigerator for 7 to 10 days. If you need longer-term storage, they can be kept in a cold, moist place for 2 to 5 months. Alternatively, they can be frozen or left in the ground with a layer of mulch to protect them over the winter months.
Fun Facts About Sunchokes: History, Varieties, And Interesting Tidbits
Sunchokes have a fascinating history and offer some interesting tidbits for gardening enthusiasts. They are native to North America and were initially cultivated by Native American tribes. The name “Jerusalem artichoke” is believed to have originated from a mispronunciation of the Italian word “girasole,” which means sunflower, due to the plant’s resemblance to sunflowers.
The recommended variety to grow is ‘Stampede.’ However, there are various other varieties available, each with its own unique characteristics. It’s worth noting that Frieda Caplan coined the term “sunchoke” in the 1960s to give Jerusalem artichokes a catchier name for selling to the masses.
Finally, it is worth mentioning that sunchokes contain high levels of inulin, a type of carbohydrate that may cause gas in some individuals. Cooking the tubers can help alleviate this issue.
Growing sunchokes can be a rewarding experience for both gardeners and food enthusiasts alike. With their perennial nature, ease of cultivation, and versatile culinary uses, these root vegetables deserve a place in your garden and kitchen. Provided with the right growing conditions and proper care, sunchokes can offer a bountiful harvest of delicious tubers year after year.

Are sunchokes hard to grow?
Sunchokes, also known as Jerusalem artichokes, are surprisingly easy to grow. They possess a sunflower-like bloom that not only adds aesthetic appeal but also signals a plentiful harvest. Unlike many crops, these plants require minimal intervention, as they do not need trellising or pruning. With their low maintenance requirements and stunning blooms, sunchokes make for a hassle-free addition to any garden.
Where is the best place to plant sunchokes?
The best place to plant sunchokes would be along a sunny fence in a well-drained section of the garden. This strategic placement not only allows the sunchokes to receive ample sunlight but also provides a privacy screen and adds a touch of beauty with their flowers. Additionally, being able to harvest the edible tubers in late fall or early spring gives a valuable food source when other options may be limited.
How many sunchokes can you get from one plant?
One plant of sunchokes can yield an impressive bounty. With their sturdy stems serving as a versatile living screen, it would be wise not to overplant. Five plants should suffice, as each tuber has the potential to produce up to twenty sunchokes. Plant them at a depth of 4-6 inches and keep them 12-18 inches apart for optimal growth.
How do you grow sunchokes from seed?
To grow sunchokes from seed, begin by planting Jerusalem artichoke seeds approximately 3 inches apart and at a depth of 3 inches. However, if you opt for tubers instead of seeds, ensure they are spaced further apart, at least 1 foot. Tubers should be planted slightly deeper than seeds, around 4-6 inches below the soil surface. Following these simple guidelines will set you on the path to successfully cultivating sunchokes from seed and witnessing their growth.
