Heat warning for zone 10b: Zone 10b 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.
