One crop that tends to pique interest is the Jerusalem artichoke. These quirky tubers, sometimes called sunchokes, are not only delicious but also quite easy to grow in containers. Let me guide you through the process of growing Jerusalem artichokes in pots and grow bags, perfect for those of us in the UK.
Quick Answer
To grow Jerusalem artichokes in containers, choose a pot or grow bag at least 60 cm deep, plant tubers 15 cm deep in spring, and water regularly. Harvest in late autumn.
Choosing the Right Container
When it comes to growing Jerusalem artichokes in containers, size does matter. These plants can grow quite tall, so opt for a container or grow bag that is at least 60 cm deep and wide. This will give the tubers plenty of room to develop underground.
- Use containers with good drainage holes.
- Consider grow bags for easy handling and storage.
- Ensure the container is stable to support tall plants.
Planting Jerusalem Artichokes
When to Plant
In the Midlands, the best time to plant Jerusalem artichokes is in early spring, around March or April, once the risk of frost has passed. This timing allows the tubers to establish before the growing season kicks in.
How to Plant
Fill your container with a good-quality, well-draining compost. Plant the tubers about 15 cm deep and space them at least 30 cm apart if you're using a large container. Cover them with soil, water in well, and place the container in a sunny spot.
Caring for Your Plants
Jerusalem artichokes are pretty low maintenance, but there's a few things to keep in mind:
- Water regularly, especially during dry spells, to keep the soil moist.
- Feed with a balanced liquid fertiliser every few weeks to encourage growth.
- Stake the plants if they start to get top-heavy.
Harvesting Jerusalem Artichokes
You can start harvesting your Jerusalem artichokes in late autumn, around October or November. The first frost can improve their flavour, so don't rush to dig them up. Use a garden fork to carefully lift the tubers from the soil.
