When to Plant Chives
Planting Window - Seed, division, or transplant
- Start seed indoors (optional)
- 8-10 weeks before last frost
- Transplant, divide, or direct-sow
- ~2 weeks before last frost
| USDA Zone | Typical Window |
|---|---|
| Zone 5 and colder | April; dies back and returns from the roots each spring |
| Zone 6-7 | March-April; growth may only pause over a mild winter |
| Zone 8 and up | Nearly any time outside peak summer heat; often evergreen |
Chives stand apart from the other alliums on this site in one basic way: they're a true perennial, planted once and then coming back on their own for years, rather than an annual crop replanted each season the way onions, garlic, and leeks all are.
Starting From Seed or Division
Seed is one route into chives - indoors, roughly 8-10 weeks ahead of the last frost date - but dividing an existing clump (your own or a nursery-bought one) into smaller sections and transplanting those gets to a usable-sized plant far faster, which is why many gardeners skip the seed-starting step entirely for this particular crop.
Transplanting or Direct Sowing
Chives are genuinely frost-hardy and can go into the garden as seed-started transplants, divisions, or, in mild climates, direct-sown seed - divisions are the fastest route to a clump worth cutting from, while direct-seeding is the slowest of the three and mainly useful where no established plant is available to divide from.
Garlic Chives Are a Different Species Entirely
Garlic chives (Allium tuberosum) are commonly sold alongside common chives (Allium schoenoprasum) but are a genuinely different species - flat rather than round leaves, a garlicky rather than onion-forward flavor, and typically later, white rather than purple flowers. They're grown and planted almost identically, but a gardener expecting the standard onion-flavored chive from a garlic chive plant will be surprised by the flavor difference.
Established Clumps Benefit From Division Every Few Years
Similar to oregano or yarrow, a chive clump left undivided for many years gets congested at the center and less vigorous overall - digging up and splitting an established clump every three to four years, replanting the healthiest outer sections, keeps a planting productive rather than letting it slowly decline in place.
Shearing the Whole Clump Encourages New Growth
Established chive clumps tolerate hard, frequent cutting well - shearing the whole clump down to about two inches above the soil rather than snipping individual stems encourages a flush of tender new growth and is the standard way to keep a planting productive through a long season.

Frequently Asked Questions
Do I need to replant chives every year the way I do with onions?
No - that's the main practical difference between chives and the other common alliums. The clump dies back to the roots each winter and regrows on its own every spring, and an established planting often self-seeds a bit into the surrounding soil too, so one planting can realistically keep a kitchen supplied for a decade or more without ever repurchasing seed or sets.
Is it faster to start chives from seed or from a division of an existing plant?
Division wins on speed by a wide margin - a split-off section of an existing clump is already a mature plant that just needs to settle into new soil and resume growing, while chives grown from seed typically need a full season before there's enough leaf mass for regular cutting.
Do garlic chives spread or self-seed more aggressively than common chives?
Yes, noticeably so - garlic chives self-seed readily and can turn into a spreading, borderline weedy patch if the flower heads are left to go to seed each year, more so than common chives typically do. Deadheading spent flowers before they set seed keeps a garlic chive planting contained to where you actually want it.
