How Many Chive Plants per Square Foot?
4 chive plants per square foot, in a 2 by 2 grid, 6 inches apart. Unlike most square foot crops, that number is not 4 seedlings you replant every spring. Chives are a hardy perennial that grows in clumps, so 4 per square means 4 starter clumps, and it is the same 4 clumps widening in place for years, not a fresh planting.
The spacing pattern
| Per square foot | 4 clumps, in a 2 by 2 grid |
|---|---|
| Inches apart | 6 inches, clump to clump |
| 4 x 4 bed (16 squares) | up to 64 chive clumps |
| 4 x 8 bed (32 squares) | up to 128 chive clumps |
| 3 x 6 bed (18 squares) | up to 72 chive clumps |
That is the count on my square foot gardening chart, and the Plan My Garden planner spaces chives the same way, 4 plants to each 1 x 1 foot cell. Treat that as a starting count, not a permanent one: 4 clumps to a square the day you plant, and the same 4 clumps a few years later, just bigger.
A perennial clump, not a fresh planting every year
University of Wisconsin-Madison Extension describes chives as a hardy herbaceous perennial that grows in dense clumps of slender bulbs, each bulb sending up hollow leaves 8 to 20 inches long, keeping the same root system year after year. Pack 4 into one square at 6 inches apart and they start with plenty of room, but both extensions recommend far more space at maturity: Wisconsin says to space clumps 12 to 20 inches apart when planting divisions, and University of Minnesota Extension puts full-grown spacing at 6 to 12 inches apart. A square foot bed packs them tighter than either recommendation, which is why a chive square fills in and needs dividing.
Both extensions agree on the fix. Wisconsin recommends dividing every 2 to 3 years to prevent overcrowding, with divisions establishing quickly as long as each piece has at least 5 bulblets. Minnesota puts the interval at every 3 to 4 years, spring being the best time, replanted in soil enriched with compost. Either way, the number on the chart stays 4 per square; what changes is the size of each clump, so plan on lifting and splitting that square every few years instead of ever replanting it from scratch.
The square stays full all winter, plan the bed around that
My vegetable frost tolerance chart lists chives among the hardy perennials that stay in the ground over winter, no cover needed. University of Wisconsin-Madison Extension explains what that looks like above ground: in cold climates the foliage is killed back by winter, though the clump survives underground and sends up new leaves the following spring, and its guidance is to remove the old dead growth in late winter before that new growth starts. That is different from an annual square that gets cleared and handed to something else every spring. A chive square holds the same clump through the winter, so when you lay out next year’s beds, leave that square out of what you replant and let the clump come back on its own.
Harvest by the leaf, not the whole clump
University of Wisconsin-Madison Extension says chives can be harvested any time once the leaves are about 6 inches long, with flavor turning more pungent in hot weather. For routine cutting, snip with scissors or a knife and cut the leaves about 2 inches from the base, taking only some leaves in a clump at a time; cut the entire clump back at once and it takes several weeks to regrow, so leave enough behind for it to keep producing. After flowering, Wisconsin also recommends cutting the whole clump back to about 3 inches high to force fresh, tender new growth. University of Minnesota Extension adds one more step: cut the flower stalks off at the soil line once the blooms finish, which keeps the plant from putting energy into seed and keeps it more productive.
The flowers are edible too
University of Minnesota Extension describes small puffs of lavender flowers opening in late May or June that are edible, good in salads and flower arrangements. University of Wisconsin-Madison Extension agrees the flowers are edible and notes they can be dried for arrangements too, though the petal color fades once dried. Left alone, chives also self-seed readily from those same flowers; Wisconsin says deadheading after they fade reduces or eliminates volunteer seedlings around the clump, lining up with Minnesota’s advice to cut the spent flower stalks off at the soil line.
When to plant chives
These are the windows the Plan My Garden planner and my seed starting calendar use, counted from your average last spring frost. Turn the weeks into dates with the seed starting calendar, or enter your zip code on Plan My Garden.
| Start indoors | 12 weeks before to 10 weeks before your last frost |
|---|---|
| Transplant out | 1 week after to 2 weeks after your last frost |
| Direct sow / divisions | No separate week in the planner. University of Minnesota Extension plants rooted clumps in spring once frost danger has passed, matching the transplant window above. |
| Days to maturity | about 90 days on my vegetable days to maturity chart, for a first harvest from seed. A division with roots and bulblets already in place establishes and can be cut much sooner. |
| Frost tolerance | Hardy on my vegetable frost tolerance chart, one of the hardy perennials that overwinters in place without a cover |
Seed
Wood Prairie carries organic Staro chives, 80 days, a packet of about 200 seeds that plants a 10 to 20 foot row, more if you start it as transplants first: organic Staro chives seed. The plants top out around 12 inches with the same lavender flowers described above. Code PMG5 takes 5 percent off.
Quick questions
How many chive plants fit in a 4×8 raised bed?
Up to 128 clumps at 4 per square, 6 inches apart. A 4×4 bed holds up to 64 and a 3×6 bed holds up to 72, but that is a starting count. The same clumps widen over a few years and need dividing, not replanting.
Is 4 chives per square a one-time planting?
Yes, in the sense that you are not resowing it each year. Chives are a hardy perennial clump. University of Wisconsin-Madison Extension says to divide clumps every 2 to 3 years and University of Minnesota Extension says every 3 to 4 years, both to keep the clump from overcrowding its square.
Do you need to replant a chive square every spring?
No. My vegetable frost tolerance chart lists chives as a hardy perennial that stays in the ground over winter. University of Wisconsin-Madison Extension says the foliage dies back in cold climates but the clump survives underground and sends up new leaves in spring, so leave that square out of your replanting plans.
How do you harvest chives so they keep growing?
Cut some of the leaves in a clump at a time, about 2 inches from the base, rather than shearing the whole clump at once. University of Wisconsin-Madison Extension says cutting an entire clump back takes several weeks to regrow, while leaving some leaves behind keeps it producing continuously.
Can you eat chive flowers?
Yes. University of Minnesota Extension and University of Wisconsin-Madison Extension both say the lavender flowers are edible, good in salads, as a garnish, or in arrangements. Cutting the spent flower stalks off at the soil line after they bloom also keeps the plant from self-seeding into the beds around it.
Let the planner place them
Even a perennial square starts with a plan. Plan My Garden is free to start: enter your zip code, draw your beds, pick chives and everything else you want to grow, and it places each plant at square-foot spacing and builds a planting schedule from your frost dates.
