2. Getting Started
To get started with growing Jerusalem artichokes, it is important to choose a suitable location with full sun and well-draining soil. Jerusalem artichokes thrive in alkaline soil that is not too rich, so it’s important to prepare the soil by removing weeds and adding compost. Plant the tubers 10-15cm deep and 30cm apart, with rows spaced 1.5m apart. If you’re growing in a pot, use fertile, peat-free compost and ensure the pot is large enough to accommodate the plants.
Key Steps to Getting Started:
– Choose a sunny location with well-draining soil
– Prepare the soil by removing weeds and adding compost
– Plant the tubers 10-15cm deep and 30cm apart
– Space rows 1.5m apart
– If growing in a pot, use fertile, peat-free compost
By following these steps, you can ensure that your Jerusalem artichokes have the best possible start and are set up for a successful growing season.
3. Care and Maintenance
Watering
Jerusalem artichokes require regular watering, especially during dry spells. It is important to keep the soil consistently moist but not waterlogged. Water the plants at the base to avoid wetting the foliage, which can lead to disease.
Earthing Up
Similar to potatoes, earthing up the soil around Jerusalem artichoke plants can help increase the harvest. This involves drawing up soil around the stems to provide stability and encourage the growth of additional tubers.
Pruning
While Jerusalem artichokes do not require extensive pruning, cutting back the stems to within a few centimeters of soil level once they die back in autumn can help facilitate the harvesting process. It is also important to remove any dead or diseased foliage to maintain plant health.
4. Harvesting and Storage
Once the stems of the Jerusalem artichokes have died back in the autumn, it is time to harvest the tubers. Cut back the stems to within a few centimeters of soil level and carefully lift the tubers as needed throughout the winter. It is important to leave some tubers in the ground to grow the following year and continue the cycle.
Harvesting Tips:
– Use a garden fork to gently loosen the soil around the tubers before lifting them.
– Be careful not to damage the tubers during the harvesting process.
– Store any harvested tubers in a cool, dark place to prevent them from sprouting prematurely.
Storage:
The tubers can be kept in the ground, especially in areas where the soil does not freeze. In colder regions, it is advisable to spread a thick surface mulch of straw or wood chip over the area where the tubers are planted. Alternatively, the tubers can be lifted and stored in boxes filled with damp sand in a cool outbuilding. If storing in the fridge, place the tubers in sealed plastic bags and they can keep for up to a fortnight.
Following these harvesting and storage tips will ensure that you have a fresh supply of Jerusalem artichokes for culinary use throughout the winter months.
5. Troubleshooting and Additional Tips
Pest and Disease Control
Jerusalem artichokes are generally resistant to pests and diseases, but they can occasionally be affected by slugs, snails, and aphids. To control these pests, you can use organic methods such as handpicking, introducing natural predators, or using insecticidal soap. Keep an eye out for any signs of disease, such as powdery mildew or rust, and promptly remove and dispose of any affected plants to prevent the spread.
Optimal Harvesting Time
To ensure the best flavor and texture, it’s important to harvest Jerusalem artichokes at the right time. Wait until the stems have died back in autumn before harvesting. The tubers can be left in the ground and harvested as needed throughout the winter. However, if you plan to store them, it’s best to harvest them before the ground freezes. Tubers that are left in the ground should be harvested before they start sprouting in the spring.
Storage and Preservation
Jerusalem artichokes can be stored for several months if properly preserved. After harvesting, brush off any excess soil and allow the tubers to dry for a few hours. Store them in a cool, dark, and well-ventilated place to prevent sprouting. If you prefer, you can also store them in the refrigerator in sealed plastic bags for up to two weeks. Check the tubers regularly for any signs of spoilage and remove any that are soft or moldy.
In conclusion, growing Jerusalem artichokes in your garden can be a rewarding and low-maintenance addition. Their versatile culinary uses and ability to thrive in various climates make them a great option for home gardeners looking to expand their harvest. With proper care and attention, you can enjoy a bountiful supply of these delicious tubers right from your backyard.
