2. Planting Jerusalem Artichokes in February

2.1 Where to Plant

Choose a sunny or partially shaded location with well-drained soil.
Jerusalem artichokes are vigorous growers and can spread, so consider planting them in a dedicated bed or containers to control their growth.

2.2 Preparing the Soil

Dig over the soil to remove weeds and break up any clumps.
Enrich the soil with compost or well-rotted manure to improve fertility.
Ensure the soil is free-draining to prevent waterlogging.

2.3 Planting Process

Dig planting holes 4–6 inches deep and space them 12–18 inches apart in rows.
Place one tuber in each hole with the pointed end facing upwards.
Cover the tubers with soil and water lightly to settle the soil.

3. Caring for Jerusalem Artichokes

3.1 Watering

Water regularly during dry spells, especially when the plants are actively growing.
Avoid overwatering, as this can lead to waterlogged soil and rotting tubers.

3.2 Feeding

Apply a balanced fertilizer or compost around the plants in mid-season to promote healthy growth.

3.3 Mulching

Add a layer of mulch around the base of the plants to suppress weeds, retain moisture, and regulate soil temperature.

3.4 Supporting Plants

As Jerusalem artichokes can grow over 6 feet tall, they may require staking or support to prevent them from toppling in strong winds.

4. Common Pests and Diseases

4.1 Pests

Slugs and Snails: Protect young shoots with organic barriers or traps.
Aphids: Spray with insecticidal soap or introduce natural predators like ladybirds.

Jerusalem artichokes are typically ready to harvest 120–150 days after planting, usually in late autumn or winter.
Wait until the plants’ foliage dies back to allow the tubers to mature fully.

5.2 How to Harvest

Use a garden fork to gently loosen the soil around the plants.
Lift the tubers carefully to avoid damaging them.
Harvest only what you need, as tubers store well in the ground throughout winter.
