These knobbly tubers, also known as sunchokes, are a fantastic addition to any vegetable garden. They thrive in the UK climate, particularly here in the Midlands, and harvesting them at the right time is crucial for the best flavour and yield.
Quick Answer
The best time to harvest Jerusalem artichokes in the UK is from late October through to February, depending on your local climate and the growing conditions. Use a garden fork to carefully lift the tubers from the soil.
Understanding the Jerusalem Artichoke
Jerusalem artichokes are a type of sunflower, and their tubers are edible. They’re a hardy plant, ideal for the British climate. They can grow quite tall, so make sure to plant them in a spot where they have plenty of room.
When to Harvest
The key to harvesting Jerusalem artichokes is timing. In the UK, they are typically ready from late autumn to early spring. The foliage will start to die back after the first frost, which is your cue that the tubers underground are mature.
| Month | Activity | Notes |
|---|---|---|
| October | Monitor plants | Foliage begins to die back |
| November - February | Harvesting period | Ideal harvesting time |
How to Harvest
When you're ready to harvest, choose a dry day if possible. Use a garden fork to gently dig around the base of the plant. Be careful with the tubers as they can be quite delicate.
- Use a garden fork instead of a spade to avoid damaging the tubers
- Start digging around the base of the plant, about 30 cm out
- Lift the tubers carefully to keep them intact
Storing Jerusalem Artichokes
After harvesting, you can store Jerusalem artichokes in a cool, dark place. They can last several months if stored properly, making them an excellent winter vegetable.
Alternatively, you can leave them in the ground and dig them up as needed, provided the ground isn’t frozen.
