• Mulching: Apply organic mulch to conserve moisture, suppress weeds, and maintain stable soil temperatures.

Watering and Maintenance

• Water Deeply: Provide consistent, deep watering, preferably with drip irrigation to ensure moisture reaches the roots.
• Fertilization: Use a balanced, slow-release fertilizer or side-dress with compost every few weeks.
• Pest Management: Monitor for aphids and fungal diseases; use organic insecticides like neem oil if needed.
• Harvesting: Jerusalem artichokes are typically ready in late autumn when the foliage dies back. Dig carefully to avoid damaging the tubers.

Troubleshooting Common Challenges

• Soil Compaction: Use a garden fork or tiller to aerate the soil regularly.
• Excess Moisture: If the soil stays too wet, consider raised beds or adding sand to improve drainage.
• Pest Issues: While sunchokes are generally pest-resistant, early detection and organic treatments can prevent infestations.
