Companion Planting & Garden Value: Rocoto Pepper

Capsicum pubescens

Spacing: needs about 4 square feet per plant. Mature height: 3-4 ft.

Plant these nearby

• 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. (source)
• 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.

Keep these apart

• Bush Beans: Beans can host bacterial blights that affect peppers.
• Tobacco: Tobacco mosaic virus survives in cured tobacco leaf and spreads by touch, so wash hands after handling tobacco (or smoking) before working with pepper plants. (source)
• Collard Greens: Commonly reported as a poor neighbor for collards.
