Chives in Zone 8a & 8b
Allium schoenoprasum
Yes, chives grow in zones 8a and 8b. Start seeds indoors Jan 28–Feb 4 and plant out Mar 11–Mar 18.
When to plant chives in zone 8b
Zones 8a and 8b share the same average frost dates, so this page covers both.
Method: Either: Start indoors for an earlier harvest, or direct-sow outside for less fuss. Either works.
| Start indoors | Jan 28–Feb 4 |
|---|---|
| Direct sow / transplant outside | Mar 11–Mar 18 |
| Estimated harvest | May 10–May 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 fit zone 8's season
Zone 8b's frost-free window runs about 230 days, from March 25 to November 10. Chives need about 60 days from sowing to first harvest.
