Growth Stages

Dormant/Storage

Variable, 1-6 months storage

Shallot sets are stored bulbs or cloves in dormancy, appearing papery and dry with no visible growth.

Store sets in cool (50-60°F), dry conditions before planting. Choose firm, disease-free sets. Chill vernalizing varieties at 40-45°F for 8-12 weeks before spring planting if needed.

Sprouting & Root Development

3-4 weeks

Green shoots emerge 2-3 weeks after planting; fine white roots develop from the base of the clove.

Ensure consistent soil moisture. Mulch lightly to retain moisture and regulate soil temperature. Monitor for fungal issues in cool, wet conditions.

Vegetative Growth

6-8 weeks

Multiple green shoots grow from each planted clove, forming a bushy tuft of upright foliage. New bulblets begin forming at the base underground.

Maintain even moisture and full sun exposure. Apply balanced fertilizer (0-0-0 or 10-10-10) every 3-4 weeks. Remove any flower stalks if they appear. Thin weeds regularly.

Bulbing & Maturation

3-4 weeks

Foliage yellows and topples as bulb clusters enlarge underground. The plant redirects energy to bulb swelling rather than leaf growth.

Reduce watering gradually as foliage dies back. Stop fertilizing. Maintain weed control. Gently lift soil to expose shoulders of bulbs for air circulation if desired.

Harvest & Curing

2-4 weeks curing

Foliage completely browns and dries. Bulbs have papery skin and feel firm. Lifted bulbs show connected clusters of bulblets.

Pull or dig bulbs when 50-75% of tops are completely brown. Cure in warm (70-75°F), well-ventilated location for 2-4 weeks before storage. Trim roots and tops once fully dry.

Harvest Tips

Harvest when 50-75% of foliage has dried and turned brown, typically in late June through July depending on planting date. Gently dig bulbs to avoid bruising. Cure in a warm (70-75°F), airy location for 2-4 weeks before storing. When fully cured, trim dried roots and foliage 1 inch above the bulb. Store in cool (45-55°F), dry, dark conditions in mesh bags or braids for up to 6-8 months.

Fun Facts

🌱 Shallot Gray is a French heirloom variety prized by French chefs since the 18th century, where it's considered essential for authentic French cuisine and fine dining applications.
