Chives in Zone 6a & 6b
Allium schoenoprasum
When to plant chives in zone 6b
Zones 6a and 6b share the same average frost dates in our data, so this page covers both.
Method: Either: Start indoors for an earlier harvest, or direct-sow outside for less fuss. Chives tolerates either.
| Start indoors | Feb 28–Mar 7 |
|---|---|
| Direct sow / transplant outside | Apr 11–Apr 18 |
| Estimated harvest | Jun 10–Jun 17 (~60 days after planting) |
Spacing: 9 per square foot (square-foot-gardening spacing). Mature height: 1-1.5 ft.
Chives are the easiest allium in the garden, a perennial clump that comes back every spring, tolerates cold well, and asks for almost nothing once it's established.
How chives fits zone 6's season
Zone 6b's frost-free window runs about 173 days, from April 25 to October 15. Chives needs about 60 days from sowing to first harvest.
