Jerusalem artichokes are drought-tolerant once established, but regular watering, especially during dry spells, promotes better tuber development and plant vigor.

Aim for consistently moist soil, avoiding waterlogged conditions. Water deeply at the base of the plant to encourage strong root growth and reduce the risk of fungal diseases.

Pruning is primarily for management rather than plant health. Cut back the dead stalks in late autumn or early spring before new growth emerges. This removes habitat for pests and makes harvesting easier.

Some gardeners pinch back the tops in mid-summer to encourage bushier growth and prevent flopping.

Jerusalem artichokes are easily propagated by dividing their tubers.

In early spring, just as new shoots begin to emerge, carefully dig up existing clumps and separate them into pieces, ensuring each piece has at least one 'eye' or bud.

Replant these divisions immediately into well-prepared soil.

Repotting is not applicable to Jerusalem artichokes as they are typically grown directly in the ground and are perennial tubers. If grown in large containers, the tubers can become quite extensive, and division or replanting into a larger container might be necessary every few years to manage overcrowding and rejuvenate growth.
