What Are the Benefits of Harvesting Jerusalem Artichokes?

Harvesting your own Jerusalem artichokes has several benefits. First and foremost, it allows you to control the quality of the tubers you are consuming. By growing and harvesting them yourself, you have complete knowledge of the soil they were grown in and any pesticides or fertilizers used.

Moreover, harvesting Jerusalem artichokes can save you money in the long run. These tubers can be quite pricey at the grocery store, but by growing them yourself and properly storing them, you can enjoy a continuous supply for months to come.

What Will You Need?

To start growing your Jerusalem artichokes, you will need a few essential items:

• Jerusalem artichoke tubers (also known as sunchokes)
• Garden soil or potting mix
• Compost or organic fertilizer
• Digging tool or shovel
• Watering can or hose

Once you have these items, you can begin the process of planting and growing your own Jerusalem artichokes.

10 Easy Steps on How to Harvest Jerusalem Artichokes

Step 1. Wait for the Right Time 

The perfect time to harvest Jerusalem artichokes is after the first frost in late fall or early winter. The frost helps sweeten the tubers, enhancing their flavor. You will notice that the foliage of the plant starts to turn yellow and die back, which is a natural indicator that the crop is ready to be harvested. However, if frost has not yet occurred in your area, you can still harvest once the plant has matured, usually 120 to 150 days after planting. Remember that waiting too long may cause the tubers to become harder to dig if the ground freezes completely.

Step 2. Cut Back the Stalks 

After determining that your crop is ready to be harvested, the next step is to cut back the stalks of the plants. Using a sharp garden tool, such as pruning shears or a machete, carefully trim the stalks down to about an inch or two above the soil level. This process not only makes it easier to access the tubers but also helps prevent any potential damage to the roots during harvesting.

It’s essential to ensure your tools are clean and sharp to avoid introducing diseases or causing unnecessary harm to the plants. Cutting back the foliage also removes excess plant material, which can be composted later to enrich your soil for future planting seasons. Take care to dispose of any diseased or unhealthy plant matter as it can harbor pests or pathogens that may affect future crops.

Step 3. Loosen the Soil 

Once the plants have been trimmed back, the next step is to loosen the soil around the roots. Use a garden fork or a similar tool to gently loosen the soil without damaging the roots or surrounding plants. This process allows for easier removal of the plant and ensures that the soil remains aerated and healthy.

Start by working a small section at a time, being mindful of the depth to avoid cutting into any roots. Properly loosened soil not only facilitates planting or transplanting but also encourages better water absorption and promotes robust root growth for the next planting season.

Step 4. Dig Up the Tubers 

Using a garden fork or spade, carefully dig around the base of the plant to lift the tubers from the soil. Insert the tool at a safe distance from the stem to avoid piercing or damaging the tubers. Gently pry the tubers loose, working your way around them as you lift. Once exposed, shake off excess soil and inspect the tubers for any signs of damage or rot, discarding any that are not healthy. Handle them with care to prevent bruising, as this could impact their quality or storage potential.

Step 5. Separate Tubers from Stems 

Using a sharp, clean pair of garden shears or scissors, carefully cut each tuber free from the main stem. Ensure that each tuber retains a small portion of the stem or “neck,” as this can enhance durability during storage. Avoid pulling or twisting the tubers off, as this can cause unnecessary damage. Place the separated tubers in a clean container or on a soft surface to prevent bruising.

Step 6. Wash and Dry Them 

Gently rinse the tubers under cool, running water to remove any remaining soil or debris. Be careful not to scrub too hard, as this can damage the skin of the tubers. After washing, lay the tubers out on a soft, dry towel or a mesh rack in a well-ventilated area. Allow them to air dry completely, which may take a few hours to a day, depending on the climate. Ensuring the tubers are fully dry will help prevent mold or rot during storage.

Step 7. Harvest Gradually if Needed 

If you are not planning to use all the tubers right away or prefer to keep them in the ground for an extended period, you can harvest them gradually. This approach is particularly useful in regions with mild winters or when you are unsure of your immediate needs. Begin by carefully digging up only the tubers you intend to use, ensuring you minimize disturbance to the surrounding soil and plant structure.

Leaving the remaining tubers in the ground can help maintain their freshness, as long as the soil conditions are not too wet or frozen. Monitor the weather to ensure optimal digging conditions, and always handle the tubers gently to avoid bruising or damage.

Step 8. Store Properly 

Proper storage is crucial to extend the life of your harvested tubers. Begin by brushing off excess soil gently—avoid washing them unless necessary, as moisture can lead to rot. Place the tubers in a cool, dark, and well-ventilated area, ensuring the temperature stays between 40°F and 50°F. Use storage containers such as wooden crates, cardboard boxes, or mesh bags that allow for airflow. Line the containers with materials like newspaper or straw to provide insulation and prevent direct contact between tubers.

Step 9. Replant for Next Season 

When the next growing season approaches, inspect your stored tubers for any signs of damage or decay before replanting. Select healthy, firm tubers with visible eyes or buds for the best results. Prepare the soil by enriching it with organic matter and ensuring proper drainage to promote healthy growth. Plant the tubers at the appropriate depth, usually 4-6 inches deep, with the sprouting eyes facing upward. Space them adequately to avoid overcrowding and allow room for development.

Step 10. Enjoy Your Harvest 

Once your plants have fully matured, it’s time to reap the rewards of your hard work. To harvest, carefully lift the plants from the soil, taking care not to damage the tubers. Brush off any excess soil and allow them to cure in a cool, dry place if needed, which helps enhance their flavor and shelf life. Enjoy your fresh, homegrown produce in various dishes, or store it properly to savor later. The satisfaction of growing and harvesting your food is truly unparalleled, making all the effort worthwhile.

By following these tips, you can successfully grow a variety of root vegetables in your garden.

5 Things You Should Avoid

1. Harvesting Too Early: Avoid digging up Jerusalem artichokes before they have fully matured. Wait until after the first frost, as this helps improve their flavor and ensures they are ready for harvest.
2. Using Improper Tools: Do not use tools that could damage the tubers, like sharp shovels or spades. Instead, opt for a garden fork to gently loosen the soil and reduce the risk of cutting or bruising the tubers.
3. Neglecting to Handle Them Carefully: Rough handling during harvest can result in bruising or breaking the tubers, which can shorten their shelf life. Be sure to handle them gently to maintain their quality.
4. Leaving Tubers Exposed to Sunlight: Avoid letting the harvested Jerusalem artichokes sit in direct sunlight for extended periods. Prolonged exposure can cause them to dry out or develop green and bitter spots.
5. Forgetting to Clean and Store Properly: Skipping the cleaning or storage process can lead to rot or spoilage. Brush off excess soil and store the tubers in a cool, dark place with good ventilation to preserve freshness.

Conclusion

How to harvest jerusalem artichokes successfully requires careful attention to detail and a proper understanding of the process.

By choosing the right time to harvest, handling the tubers gently, and ensuring proper cleaning and storage, you can maximize their freshness and quality. Being mindful of common mistakes, such as leaving tubers exposed to sunlight or failing to store them correctly, will help prevent spoilage and maintain their flavor.
