Benefit
- Tomato & marigoldPair
Tomatoes · French marigold (Tagetes patula)
Traditional companion: strong scent may mask tomato host cues for some pests; root exudates are debated—treat as a helpful row edge, not a pesticide.
- Calendula near vegetablesPair
Calendula · Mixed veg bed
Long-blooming calendula supports generalist pollinators; some predatory insects visit composite flowers—pair with good habitat, not sprays.
