Pepper in Zone 8a & 8b
Capsicum annuum
When to plant pepper in zone 8b
Zones 8a and 8b share the same average frost dates in our data, so this page covers both.
Method: Start indoors: Start indoors from seed, then transplant outside. Pepper needs a head start most zones can't give it by direct-sowing alone.
| Start indoors | Jan 28–Feb 4 |
|---|---|
| Direct sow / transplant outside | Apr 8–Apr 15 |
| Estimated harvest | Jun 22–Jun 29 (~75 days after transplanting) |
Spacing: 1 per square foot (square-foot-gardening spacing). Mature height: 1.5-3 ft.

Peppers are close cousins to tomatoes in care, but slower to get going and less forgiving of a cold snap. They stall out below about 55°F, where tomatoes just slow down. That's why our planting calendar generally has peppers starting indoors even earlier than tomatoes.
How pepper fits zone 8's season
Zone 8b's frost-free window runs about 230 days, from March 25 to November 10. Pepper needs about 75 days from transplant to first harvest.
Good companions
- Basil: Reputed to repel aphids and improve pepper growth nearby, but a controlled garden trial testing this same claim on a related crop found no pest-reduction benefit from basil, and actually found higher pest counts on the basil-companioned plants — treat this pairing as unproven, not as a working pest deterrent.
- Onion: Reputed to deter many common pepper pests, though this specific pairing hasn't been tested the way onion/carrot pest-masking has — treat it as garden tradition.
