Tomato & marigold
PairTomatoes with 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.
In the garden
- Use as a low border or scattered spots—not a tight ring that blocks airflow.
- Deadhead for tidy beds; allow a few late flowers if you want pollinator support.
Spacing & timing
Keep marigolds at bed edges or between plants with at least a hand-span gap to tomato stems.
