Shallots

Allium cepa var. aggregatum

Family: Amaryllidaceae

Shallots are the gourmet cook's secret weapon, offering a milder, more complex flavor than onions with hints of garlic. Each planted bulb multiplies into a cluster. Essential in French cuisine and surprisingly easy to grow.

Days to Harvest

90-200 days

Sun Needs

Full Sun (6+ hours)

Water Needs

moderate

Germination Temp

55°F optimal

Seed Starting

Start Indoors

0 weeks before last frost

Germination

14-21 days

Seed Depth

Plant bulbs 1 inch deep

Light to Germinate

No

đź’ˇ Tip: Plant sets (small bulbs) in fall (cold climates) or late winter (mild climates). Can also grow from seed started indoors very early. Each bulb multiplies into 6-12 shallots.

History & Nutrition

History

The shallot's name derives from Ashkelon, an ancient Philistine port city in Israel where Crusaders first encountered this refined allium and brought it back to Europe. However, shallots likely originated much farther east, in Central or Southeast Asia, traveling westward along ancient trade routes. What distinguishes shallots botanically is their growth habit: unlike onions that form single bulbs, shallots multiply into clusters of smaller, elongated bulbs—a characteristic that made them self-perpetuating and valuable in traditional agriculture. French cuisine elevated the shallot to an essential ingredient, and classical French cooking technique relies heavily on its unique flavor profile—more delicate than onion, with subtle garlic notes and a sweetness that develops beautifully when cooked. The famous "reduction au vin rouge" (red wine reduction) depends on shallots, as do countless mother sauces and preparations that form the foundation of French gastronomy. The "French Gray" (Griselle) shallot, considered the true gourmet variety, can only be grown from bulbs rather than seed, maintaining its heirloom character through generations. Southeast Asian cuisines also prize shallots, particularly Thai and Vietnamese cooking where fried shallots provide crucial texture and flavor. In American cooking, shallots long remained a specialty ingredient found only in gourmet shops, but increased culinary sophistication has made them a mainstream supermarket item and a favorite of home cooks seeking refined flavors.

Climate & Temperature

Optimal Growing Temp

55°F - 75°F

Shallots prefer cool to moderate temperatures (55-75°F) for best bulb development. They tolerate light freezes and can be fall-planted in many areas for larger bulbs.

Survival Range

15°F - 90°F

Can survive these temperatures

hardy
cool Season

Frost Note: Hardy to 15°F or lower once established. Fall-planted shallots overwinter successfully in zones 5-9. Spring-planted shallots are ready before summer heat.

Best USDA Zones

Zone 5Zone 6Zone 7Zone 8Zone 9

Humidity

40-60%

Moderate humidity preferred. High humidity can cause fungal issues. Good air circulation is important.

Plant Size & Growth

Height

12-18 inches

Spread

8-12 inches (clump of multiplied bulbs)

Growth Habit

upright

biennialRoot Depth: Shallow roots, 6-8 inches. The multiplied bulb cluster sits partially above soil line at maturity.
Growth Stages

Germination

N/A for sets; 10-14 days for seeds

Sets sprout within 2-3 weeks of planting. Seeds germinate in 10-14 days in cool soil.

Seedling Stage

Duration: 3-4 weeks

True leaves: Single grass-like leaf emerges first, followed by additional leaves from the center.

Transplant ready: Sets are ready to plant as-is. Seedlings transplant when 6 inches tall.

Vegetative Growth

Duration: 8-12 weeks

Each planted set multiplies into a cluster of 6-12 bulbs. Leaves grow from each developing bulb in the cluster.

Harvest Maturity

Timing: 90-120 days from planting sets, longer from seed

  • Leaves yellow and fall over
  • Necks soften and dry
  • Bulbs have papery outer skins
  • Clusters separate easily
Expected Yield

Per Plant

6-12 shallots per planted set (multiplier effect)

Per Square Foot

12-24 shallots per square foot

Harvest Frequency

Single harvest when mature; cure for storage

Factors Affecting Yield

  • •Fall-planted shallots produce larger bulbs than spring-planted
  • •Each set multiplies into a cluster of 6-12 bulbs
  • •Proper curing essential for long storage
  • •French gray types are prized for flavor but store shorter
Watering Guide

Seedling Stage

Keep moderately moist, not wet

Established Plants

Deep watering every 5-7 days, 1 inch per week

During Fruiting

Reduce watering as leaves begin to yellow and fall

Preferred Method

Water at soil level to keep leaves dry. Drip irrigation or soaker hoses ideal. Good drainage essential.

⚠️ Critical Watering Periods

  • • Bulb development phase
  • • Must dry down before harvest

Pro Tips

  • Consistent moisture during bulb formation
  • Stop watering when leaves begin to yellow
  • Too much water causes storage problems
  • Drought stress reduces bulb size but intensifies flavor
Fertilizing Guide
light feederRecommended: Low nitrogen, higher phosphorus and potassium (5-10-10)

Feeding Schedule

At planting

Compost or balanced fertilizer

Once at planting

Midseason

Light application of balanced fertilizer

Once, 4-6 weeks before harvest

Organic Options

CompostBone mealWood ash (for potassium)

Apply compost at planting. Avoid heavy nitrogen which promotes leaf growth over bulbs.

Container Growing
âś“ Suitable for containers

Minimum Size

8 inches wide, 8 inches deep for 3-4 sets

Recommended Size

12 inches wide, 10 inches deep

Depth Required

8-10 inches for adequate root and bulb development

Best Varieties for Containers

Dutch YellowFrench GrayAmbition (from seed)

Container Tips

  • Plant sets pointed end up, just covered with soil
  • Provide good drainage—shallots rot in soggy soil
  • Space sets 4-6 inches apart
  • Excellent crop for containers due to shallow roots
  • Container shallots may produce slightly smaller bulbs

Pruning Guide
Pruning Optional

Why Prune

Remove flower stalks if they appearClean up yellowing leaves at harvest

When

Remove flower stalks immediately. Otherwise, minimal pruning needed.

How Often

As needed—check for flower stalks periodically

Technique

Cut off any flower stalks at their base to redirect energy to bulb development.

Remove

  • âś— Flower stalks
  • âś— Damaged leaves

Keep

  • âś“ All healthy green leaves until natural yellowing
