| Direct sow / transplant outside | Mar 1–Mar 8 |
| Estimated harvest | May 15–May 22 (~75 days after transplanting) |

Sweet cherry peppers are small, round red peppers about 1.5 to 2 inches across. They are the classic pepper for stuffing with cheese or cured meat and packing in oil, and for pickling whole.
How sweet cherry pepper fits zone 9's season
Zone 9b's frost-free window runs about 293 days, from February 15 to December 5. Sweet cherry pepper needs about 75 days from transplant to first harvest.
Heat warning for zone 9b: Zone 9b summer nights commonly exceed 75°F, which stalls pollination and causes blossom drop in Sweet Cherry Pepper at the height of summer (University of Maryland Extension, via UDel Cooperative Extension). Expect a slow patch for fruit set during the hottest stretch even though the plant keeps growing. It typically resumes once nights cool.

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 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.
