Same family (Solanaceae): they share diseases and pests, so a blight or wilt outbreak hits both. Culturally they grow fine together β€” the risk is disease, not competition.

Why

Layout: Fine side by side in a healthy garden, but don't rotate one into the other's spot, and separate them if you've had disease problems.

  • A real, documented or strongly plausible reason to keep these apart or plant with care β€” shared disease, allelopathy, competition, or resource mismatch.
  • Companion planting tweaks the odds β€” spacing, rotation, and airflow still matter more than any pairing.

When this doesn't apply

  • Small gardens with no disease history can often get away with it β€” the rating protects against the bad year, not the average one.
