Slow crops, long memories, and why winter decides your harvest
Onions and chives don’t reward urgency. They reward time. They grow slowly, think carefully, and never forgive a late start. While other gardeners are still thumbing seed catalogs in March, experienced growers already have pencil-thin onion seedlings standing at attention and chives quietly thickening their roots.
If you want real bulbs and usable clumps—not thin green apologies—winter protection is where the work begins.
Why Onions and Chives Are Started Early
These are not heat-driven crops. They are governed by day length and duration, not enthusiasm.
-
Onions need weeks of leafy growth before day length triggers bulbing
-
Chives take time to establish strong perennial clumps
-
Both grow slowly at first and cannot make up lost time
A late start means:
-
Small onion bulbs
-
Weak chive plants the first year
-
A season spent waiting instead of harvesting
Winter protection gives them the one thing they demand: an early, steady beginning.
Onion Seeds: Winter Starts Are the Rule, Not the Exception
Starting onions from seed is the old way—and still the best way—if you want control over varieties and bulb size.
How to Start Onion Seeds Under Protection
Temperature
-
Germination: 65–75°F
-
Once sprouted, cooler temperatures are better
-
Onions prefer cool air and bright light
Light
-
Strong light immediately after emergence
-
Grow lights or a bright windowsill work well
-
Leggy onions stay weak forever
Soil & Sowing
-
Fine seed-starting mix
-
Sow shallow (about ¼ inch deep)
-
Keep evenly moist, never soggy
Onion seedlings should resemble green threads standing upright—not flopping over in despair.
Chive Seeds: More Forgiving, Still Better Early
Chives are hardy perennials, but starting them under protection gives you usable plants much sooner.
How to Start Chive Seeds Under Protection
Temperature
-
Germination range: 60–70°F
-
No heat mat required
Light
-
Bright but cool conditions
-
Windowsills often outperform grow rooms
Soil & Sowing
-
Sow shallow, lightly covered
-
Thin or transplant carefully
-
Chives tolerate handling better than onions
Chives started early build roots quietly and reward patience later.
Where Winter Protection Works Best
Indoors
-
Most reliable for both onions and chives
-
Allows early starts without weather risk
-
Ideal for cold and moderate zones
Greenhouses
-
Excellent if temperatures stay above freezing
-
Vent on sunny days—onions hate heat spikes
Cold Frames
-
Best for late winter sowing
-
Ideal for hardening off young plants
-
Not warm enough for earliest starts in cold zones
Protection is about stability, not warmth.
When to Start Onion and Chive Seeds by USDA Climate Zone
Using the USDA Plant Hardiness Zones, timing looks like this:
Zones 3–4 (Very Cold)
-
Start onions indoors: late February to March
-
Start chives indoors: February to March
-
Transplant outdoors: April to May
Zones 5–6 (Cold Winters)
-
Start onions indoors: January to February
-
Start chives indoors: February
-
Transplant outdoors: March to April
Zones 7–8 (Moderate Winters)
-
Start onions indoors or greenhouse: December to January
-
Start chives: January
-
Transplant outdoors: February to March
Zones 9–10 (Mild Winters)
-
Onions and chives are cool-season crops
-
Start seeds: October to December
-
Transplant outdoors: winter to early spring
Zone 11 (Tropical)
-
Grow during the coolest months
-
Start seeds: late fall
-
Avoid heat entirely
Onions follow daylight. Chives follow patience.
Transplanting: Firm, Not Fussy
-
Transplant onions while still pencil-thin
-
Trim tops if needed—this strengthens roots
-
Space properly; crowding ruins bulbs
Chives can be planted in small clumps and allowed to expand naturally.
Start Now, or Accept Smaller Results Later
Onions and chives don’t reward procrastination. Their success is decided quietly, months before harvest, while winter still holds the line.
Order your onion and chive seeds now, start them under winter protection, and give these slow, honest crops the time they require. Big bulbs and thick clumps are never accidents—they’re the result of starting early and knowing better.
