• Spacing: Space tubers 12–18 inches apart to allow ample room for tuber expansion.
• Mulching: Apply organic mulch to conserve moisture, suppress weeds, and stabilize soil temperatures.

Watering and Maintenance

• Watering: Provide deep, consistent watering; drip irrigation is highly effective.
• Fertilization: Use a balanced, slow-release fertilizer or side-dress with compost every few weeks.
• Pest Management: Monitor for aphids and fungal diseases; treat with organic insecticides like neem oil if necessary.
• Harvesting: Harvest when the foliage dies back in late autumn, digging carefully to avoid damaging tubers.

Troubleshooting Common Challenges

• Soil Compaction: Regularly aerate the soil with a garden fork or tiller to ensure proper root development.
• Excess Moisture: If overwatering occurs, improve drainage by using raised beds or adding sand.
• Pest Issues: Although sunchokes are generally pest-resistant, early detection and organic treatments can prevent infestations.
