When to plant shallot
- Direct sow: ~-4 weeks after last frost.
Companion plants for shallot
Plant with: Carrot, Beet, Lettuce.
Avoid near: Bean, Pea.
Common pests & problems
Thrips, rarely serious.
Feeding & fertilizer
N-P-K ratio: Moderate N + high P (5-10-10)
Organic options: Compost + bone meal at planting · Fish emulsion monthly through spring · Stop feeding as bulbs swell
When to feed: Feed through spring leaf growth, then stop once tops start to yellow so bulbs cure hard.
Watch for: Thick, soft necks = too much late nitrogen; bulbs won't store.
N = nitrogen (leaves), P = phosphorus (roots and flowers), K = potassium (fruit and disease resistance). How to read a fertilizer label →
Grower's tip
Plant sets pointed end up, barely covered. Each set multiplies into a cluster of 4-8 bulbs by midsummer.

Soil & water for shallot
Soil & pH
6.0-7.0
Loose, well-drained loam, similar to onion and garlic requirements.
Compost worked in before planting; avoid fresh manure, which can cause soft, poor-storing bulbs.
Watering
1 in / week during bulbing; taper before harvest
Drip; keep foliage dry to prevent purple blotch.
Falling, yellowing tops = pull water and cure.
Knowing when to harvest
- Tops yellow and flop over, similar to onions, usually 90-120 days after planting sets or transplants.
- Each planted set multiplies into a cluster of several bulbs by harvest.
- Cure in a warm, dry, airy spot for 2-3 weeks before storing, same as onions and garlic.
Storing & keeping
Cured bulbs at 40-50°F, 60-70% humidity, in mesh bags with airflow, for 6-10 months, noticeably longer than most onions.
What to expect
Per plant: 1 set multiplies into a cluster of 4-8 bulbs
Per sq ft: 9 sets per sq ft
Troubleshooting shallot
Clusters fail to divide into multiple bulbs
Likely cause: Planted too late or in soil that stayed too wet and cold, delaying multiplication
What to do: Plant in fall (mild climates) or very early spring; ensure sharp drainage.
Bulbs rot in the ground
Likely cause: Waterlogged soil, especially over winter in fall-planted shallots
What to do: Raise beds or improve drainage; shallots are less tolerant of wet feet than garlic.
Varieties worth growing
French Red (Frileuse)
Classic mild, wine-red shallot with strong storage life.
French Grey (Griselle)
Considered by many cooks the finest-flavored shallot; smaller yield but intense taste.
Ambition
Reliable hybrid producing uniform, round bulbs for home gardens.
Growing shallot in containers
10-12 in deep container; plant sets 6 in apart to give clusters room to divide.
Nutrition
Allicin, quercetin, prebiotic fiber.
Common questions
Can I plant a shallot from the grocery store?
Yes, if it is firm and untreated, though named seed stock from a supplier gives more predictable yield and disease-free starts.
Why do shallots store longer than onions?
Shallots generally have a lower moisture content and tighter skin, which slows the sprouting and rot that limits most onion storage.
