Planting Tips

Timing: Plant in early spring when soil temperatures consistently exceed 50°F.
Spacing: Space tubers 12–18 inches apart to allow for proper expansion.
Mulching: Apply organic mulch to conserve moisture, suppress weeds, and stabilize soil temperature.

Watering and Maintenance

Watering: Provide deep, consistent watering; drip irrigation is highly effective.
Fertilization: Use balanced, slow-release fertilizers or side-dress with compost every few weeks.
Pest Management: Monitor for aphids and fungal diseases; treat with organic insecticides like neem oil if needed.
Harvesting: Jerusalem artichokes are typically ready to harvest when the foliage dies back in late autumn; dig carefully to avoid damaging tubers.

Troubleshooting Common Challenges

Soil Compaction: Regularly aerate the soil with a garden fork to ensure proper root and tuber development.
Excess Moisture: Improve drainage by using raised beds or adding sand if the soil stays too wet.
Pest Issues: Although generally pest-resistant, early detection and organic treatments can prevent aphid infestations.
